Stored | Full Stack/Backend Engineer (C#, TypeScript, Postgres) | Fully Remote (European timezones only) | Full-Time

We're Stored – a digital payments startup redefining how merchants sell and get paid. We recently closed an oversubscribed funding round, driven by several new partnership agreements with some of the world's largest payments businesses.

You’ll be joining a small team where your work will have immediate and visible impact. The majority of the backend has been built by one of our founders, and you'll work closely with them to help take it to the next level.

What we’re looking for:

-Strong experience with C# and back end systems.

-Deep understanding of Postgres, performance tuning, batching, and scaling.

-Proficiency in TypeScript, and capable of owning full features end-to-end.

-Comfortable handling front end logic (we use Svelte, but experience with any modern framework like React or Vue is fine). To be clear, you won't need to design/build UIs, but you should be able to work across the stack.

-Experience with Linux and networking, especially profiling/debugging in high-traffic production environments is desirable but not essential

-Fluent in written and verbal English

-Self-disciplined, motivated, and able to manage concurrent tasks

This is a fully remote role, but we’re based out of London, UK and so only considering candidates in GMT/BST ±3 time zones who are willing to work between the hours of 8am - 6pm GMT/BST.

Please email CVs to tech-hiring[at]joinstored.com

PlantingSpace | Full-time | Remote (EU time zone) with quarterly meet-ups | https://planting.space

We’re building an AI system for analysts and scientists, based on a fundamentally new approach to reasoning and knowledge representation. Our approach differs from LLMs in that we compose algorithms symbolically to represent complex knowledge, and perform probabilistic computations. This enables the AI-driven application of statistical models to different problems, while providing the user with a verifiable reasoning path, and an assessment of the uncertainty in each answer. We are developing applications for analysis and research in domains such as Finance, Strategy Consulting, Engineering, Material Sciences, and more.

We’re currently hiring for:

* Program Synthesis Engineers

* Senior DevOps Engineers

* Senior Product Manager

* Senior UX Designer

Drone startup | Product Engineer (Typescript) | 1 day/week in the office (London, UK) | Citizens of the UNITED KINGDOM only

You'd be working with engineers who previously worked at Google, Amazon, Helsing, Darktrace and an F1 team. We build drones (software and hardware)

We're looking for engineers that straddle real world problems, and use technology as a solution. We prefer personal projects or relevant hobbies, not hard leetcode questions. We value collaboration: pair programming, discussing, teaching and learning from others. We're looking for mission-driven engineers. People who see problems in the world and want to help solve them.

You'd be working with me to build the most intuitive, performant, and modern mission planning and flight monitoring software for drones, and related applications (tools for drone design and manufacturing). For my project, we use React, Tailwind, Node, drizzle-orm, Postgres, SQLite, deck.gl, Python, FastAPI, asyncio, and more. You're allowed (and compensated) to use AI services.

Because we are a small team, you will be noticed and rewarded for performance.

*Please don’t apply if any of these resonate:*

• You prefer narrow ownership—“I only touch the backend or the code I've written”.

• You think it's more about "who you know, not what you know".

• You haven’t actively learned a new tool or hobby in the last year.

If interested, email my temporary email: hn-june25@mail.orth.uk with your CV and some personalised information about why you'd be the right fit.

Tandem Health | Software Engineers | On-site in Stockholm, Sweden | Full time

At Tandem Health we're building a clinician copilot to allow clinicians to focus on care rather than administration. We’re building, launching and iterating quickly, and already have >500 organizations using our product.

Our core product listens in to the patient-clinician encounter to generate medical records, allowing clinicians to save 5-10 minutes per patient.

Some even tell us that their partners notice they're much more relaxed after starting to use our product, and we couldn't be happier :)

We're expanding our Stockholm team with exceptional engineers! We use Python (backend), TypeScript/React (frontend) and C# (Windows app) and our infrastructure runs on Kubernetes in Azure. We're scaling rapidly in terms of # of users and are especially keen to talk to senior backend engineers who have helped startups scale from thousands to millions of users.

Even if we don’t have a role out for your specific skill set, we’d love to talk! Our tech team is small but growing and you’ll have an outsized impact on an important problem.

New Hedge fund | Sr/Staff Frontend Engineer | On-site (NYC)

We are a new discretionary, tech industry focused hedge fund, founded by a portfolio manager with 15+ years of experience at a Tiger Cub. I lead the data/technology team here and previously spent ~6 years in a similar role at a well known Tiger Cub.

We are hiring for a frontend senior/staff engineer for our internal research management web application.

Our tech stack: * Frontend: Typescript, Vue3 * Backend: Cloudflare, Supabase/Postgresql, Typescript *

Obviously, we are not the only ones trying to figure out how to use AI in investing but in a world where there are lots of people trying to build picks & shovels, this is an opportunity to be one of the goldminers at a greenfield, new firm. This role makes sense for people who are interested in finance/investing (although you do not necessarily have to have experience in the industry).

We're in full-time in office in NYC, so that's a requirement for FTE. We are potentially open to exceptional contractors located remotely.

We work very hard, hours are long, and people are very dedicated to the mission. It is not for everyone, but for those interested in competing in financial markets, love startup atmosphere without near-term existential risk, and want to work with super smart colleagues (both technical and investors!), this could be a great fit.

Target salary 180-250K, depending on experience + Bonus/Carry (hedge fund equity equivalent)

Blueberry Pediatrics | Full-stack Senior or Staff Engineer | REMOTE (US only)

American healthcare is seldom affordable, accessible, or high-quality. We are fixing this for pediatrics. Blueberry is the most affordable option amongst our competitors. We practice the highest quality pediatric telemedicine, as evidenced by our exclusive hiring of board-certified pediatricians and the usage of at-home medical kits. And, we’re accessible 24 hours a day.

Our success is shown in the lives we save, the costs we save our insurers, and our exploding B2B and D2C business.

As you can imagine, pulling off affordable high-quality healthcare is a challenge. It requires a lot of engineering ingenuity, a C-suite aligned with positive patient outcomes above short-term profits, and a great product team.

We use Django, Hotwire Turbo (an HTMX-like framework), Pytorch, Sklearn, and Flutter. Experience in these technologies helps, but what’s more important is general full-stack knowledge, curiosity, and a strong work ethic.

Ascertain is a healthcare AI startup backed by Northwell (New York's largest health system) and Deerfield. We're a small team automating the painful admin work that clogs up the U.S. healthcare system — things like prior authorizations, discharge planning, and insurance claims. Our goal is simple: give time back to clinicians so they can focus on patient care, not paperwork.

We've found early product-market fit and are growing the team thoughtfully. We're hiring senior engineers across the stack: backend, frontend, and AI/LLM. We're NYC-based and hybrid (most of us come in ~3 days/week). We're not counting badge swipes — we just want teammates who want to be in the room with us often enough to build trust, have fun, and work on hard problems together!

What we're building:

* A general-purpose automation platform for healthcare ops, powered by LLMs

* A system that reads unstructured documents, fills out payer forms, and explains rejections

* Tools to automate patient discharge planning in hospitals

* A foundation for making AI in healthcare safe, observable, and human-in-the-loop

What we're looking for:

* AI Engineer — experience productionizing LLM apps (agents, RAG, embeddings); solid Python; knows how to build ML systems that ship

* Backend Engineer — strong Python/FastAPI; infra-savvy (K8s, Terraform, Docker); thoughtful about API design and scalability

* Frontend Engineer — React/TypeScript expert who's opinionated about UX and happy to dip into backend when needed

More importantly, we're looking for engineers who like open-ended, ambiguous challenges, and want to work with a tight-knit, high-trust team to solve real-world problems.

Pleas remember that we are looking for NYC local only, no exceptions at this time :(.

VIVA Finance | Atlanta, GA | Back-End Developer

VIVA is a Fintech Startup based in Atlanta, GA with the mission to build a more inclusive financial system. VIVA offers unsecured personal loans to customers who have traditionally been excluded and taken advantage of by the legacy financial institutions. The VIVA difference is to underwrite heavily on employment history and set up repayments through voluntary direct deposit payments from the borrower's paycheck. Our interest rates are less than 1/3 of the rates our customers are able to get from other financing options.

We are a VC backed company and have been in business for 6 years. We have been profitable for the past year and with a new debt facility closing at the end of June, we will be dramatically ramping up origination volume in the second half of the year. We are hiring an additional backend engineer to support the larger transaction volume, as well as to support new products we plan to launch to diversify our revenue stream. You will join our engineering team of 10 and work in a dynamic environment where you are frequently writing net new code to support business objectives.

Our tech stack for the back-end is fully on AWS, using Lambda and ECS for compute and Typescript as the language, but experience with this specific stack is not necessary for talented candidates. Our preference is candidates who can come in office 4 days a week to our new office on the Atlanta Beltline (next to Krog Street Market).

Fullstack Developer – Kotlin + React. You'll ship end-to-end features, build new mini-apps, and contribute to the internal platform that powers them.

Product Designer – Help define a UX model for composable finance—where users can mix and match tools that feel tailored to them.

We use Kotlin (Exposed, Ktor), React + Next.js, AWS (Fargate, Lambda), MySQL, and Mongo. Our stack also supports integrating AI models directly into mini-apps.

If you’re passionate about redefining how people interact with money—and want to help build a platform others can build on too—we’d love to talk.

Reach us at jobs [at] klutchcard.com and include a quick note about what excites you about programmable finance.

We started our first product, Substrate in 2023, a platform for building agentic workflows, and raised an $8M seed round led by Lightspeed [2].

Make an Impact on Climate! Looking for Data Stores and Full-Stack Engineers (Remote, US)

At Insight M, we combine innovative aerospace systems with advanced data science. Unlike traditional aerospace companies, we sell information, not hardware - we operate our sensors cost-effectively at a continental scale to produce novel data streams about pressing global problems.

First on our list: spotting hard-to-monitor emissions of methane, a potent greenhouse gas that accelerates climate change. Since starting continuous survey operations in 2018, Insight M has removed methane emissions equal to over 250 million tonnes of CO2e through our work. To put that in perspective, that’s equivalent to over 60 million cars being removed from the roads or shutting down about one hundred and sixty 350 MW coal-fired power plants for a year. That's like planting 4.2 billion urban trees and letting them grow for 10 years.

We call that a good start.

As a team, we love science and engineering, we love getting our hands dirty with hardware and software, and we love seeing our work make a difference in the real world.

We’ve created a diverse, collaborative, supportive, and fun environment based on integrity and treating people right. So no matter your sex, gender, sexual identity, gender identity, race, age, beliefs, sexual orientation, or disabilities, we welcome you and would like to work with you. :-)

It’s never boring, it’s always challenging, and we’re usually laughing.

A note of encouragement: If you don't meet 100% of the qualifications on our open job descriptions: https://jobs.lever.co/InsightM, you should still seriously consider applying.

Individuals with a disability are encouraged to contact [interview.accommodations@insightm.com] to request assistance with your application and accommodations in advance of your interview.

Timescale - [ Global | Remote First | Multiple Roles: Eng, Product + more ]

Timescale is continuing to grow rapidly, and we’re hiring for many roles involving distributed systems and databases.

Timescale extends PostgreSQL to handle relational data, time-series, events, real-time analytics, and vector search in a single application database. It’s built for data-heavy, mission-critical apps while retaining the familiarity and reliability of Postgres. Ideal for IoT, crypto, finance, SaaS, and more.

Database code all available on github; we don’t have any “enterprise versions”, so all our database code is available for the community for free. Currently, see more than 3 million databases running TimescaleDB a month.

That’s because our commercial focus is on our fully-managed cloud platform, so in addition to folks implementing the core database (C, Rust), we’re also heavily hiring for folks with operational cloud & database experience at scale (Kubernetes with custom k8s operators, Golang, etc), as well as folks interested in providing highly technical support, database release engineering, and building database testing infrastructure (think performance analysis, distributed database correctness testing, etc.) And product folks to support these efforts & all our users!

Lots of fun engineering and product work with an amazing company culture. Check us out: https://www.timescale.com/careers

New Lantern | https://newlantern.ai | Software engineers (infrastructure engineers & backend-leaning product engineers) | Full time in San Francisco, CA (ONSITE)

New Lantern is hiring software engineers to help build an AI copilot [1] for radiologists.

Radiologists are experts at diagnosing disease in medical images, but they spend over half their working hours on tasks that have nothing to do with diagnosis: reading prior reports, transcribing handwritten notes, taking manual measurements, dictating reports, and chasing down follow-ups. New Lantern is building an AI copilot for radiologists to automate this non-diagnostic work, so radiologists can focus on what they do best: caring for patients and interpreting images.

We are starting to find product-market fit and recently raised a $19M Series A from Benchmark [2]. Demand for our product is growing, and we're hiring software engineers in San Francisco to help us scale our product and our team. We work together in person five days a week from our office in Jackson Square.

Engineering is at the heart of New Lantern. Our engineers work directly with our founder/CEO, our staff radiologist, and our end users to build features that radiologists rely on daily. Everyone has real ownership and autonomy, moves quickly, and ships meaningful work frequently. We're a small, sharp team of frontend, full-stack, and backend engineers building a React-based web app backed by Python services, cloud infrastructure, and LLMs.

I'm Steve, New Lantern's Head of Engineering. If you're interested or want to learn more, shoot me a note at (my HN username)@newlantern.ai.

[1] We translate "AI copilot" to "AI radiology resident" when we speak with medical professionals, but the former is the clearest way to communicate what we're building here.

Camber (YC W21) | Senior Software Engineer | NYC | Onsite / Hybrid | camber.health

Camber (fka Juniper) operates at the messy financial infrastructure for US Healthcare. We've built an automated end-to-end insurance billing system for recurring care, starting with Autism clinics.

At Camber, we’ve built an end-to-end billing system. We’ve built something really good, something that clinicians really need and love. We automate and abstract the tedious, manual, repetitive work that goes into the administrative duties of running a clinic, so that clinicians can do what they do best — providing high quality care. It starts with ingesting clinic data, and then create, validates, and submits claims to insurance providers across the country. If claims need corrections or appeals, most of the time we can handle those automatically or our CX and Operations team use our in-house internal tools. We also handle patient invoicing for co-pays, co-insurance, and deductibles.

We are a team of ~40 with strong product market fit — in Q4 last year we’ve had to push out onboarding because engineering can’t build quickly enough, something we’ve scaled out of. You’ll be working with an engineering leadership team from AWS and Stripe to get clinicians back to work delivering care for kids.

Solace Health | Various Roles | Remote (US Only)

The U.S. healthcare system wasn’t built for patients. It’s massive, confusing, exhausting, and designed to wear people down. It denies access, withholds clarity, fails to take patients seriously, and rarely shows them how to fix what’s broken. When care gets delayed or denied, patients are often left with more questions than answers.

At Solace, we’re on a mission to empower patients & improve outcomes. By helping people work with professional health advocates, Solace serves as an integral, personal support layer for health issues in a way that the health system can’t. Using proprietary technology to match patients with experienced advocates, Solace cuts through the red tape of healthcare and helps individuals and families make informed decisions that result in better outcomes.

Solace is a Series B startup founded in 2022 and backed by Inspired Capital, Craft Ventures, Torch Capital, Menlo Ventures and Signalfire. We have a lean, fully-remote U.S. team distributed coast-to-coast.

Adora AI | Senior Backend Engineer | Full-time | Seattle, WA | ONSITE At Adora, we're fixing performance marketing – an industry where brands get stuck with opaque algorithms that optimize for everyone except them.

Members of our team spent years at the big platforms and ad networks, and we know exactly how broken it is. Now we're building something better – a platform that finally puts brands in control with AI that works for them, not against them.

We recently raised our seed round led by Village Global (backed by Reid Hoffman, Jeff Bezos, Mark Zuckerberg). Real customers are already using our product and seeing results. Your work will directly impact how fast we can scale this thing.

What makes this interesting: • Daily work with cutting-edge AI tools, figuring out how to make them actually useful for marketers • Direct line to customers – you'll see your code impact real businesses immediately • Small team where your technical decisions matter and stick around

We're looking for someone who's shipped backend systems at scale and either loves the startup chaos or is ready to dive in. You'll own features end-to-end and have real autonomy over technical direction.

Python/MySQL/AWS/BigQuery is our current stack but we care more about your problem-solving approach.

If you want to work on hard technical problems with immediate business impact instead of yet another CRUD app, let's talk.

Small boutique consulting | Javascript Developer (Vue experience strongly preferred) | Remote (US) (some est meetings) | part-time/flexible/1099 | ~$50/hr

Hi! I work with a small group of developers doing custom software development and consulting for small/medium businesses. This is a great opportunity for people who value flexibility, maybe SAHMs, new parents, etc. who want to get back into the workforce in a very flexible way. Not a great fit for someone between who wants to do something temporary between jobs, supplemental around their existing full time job or who need a stable level of income.

The work is very different by client but not terribly difficult. However, no matter how senior you are there is a pretty low ceiling on what our clients are willing to pay. Our technology stack is anchored in: - JavaScript/Node/Vue - GCP/App Engine/Cloud Functions - Jira/Confluence/Google Workspace

Galaxy (getgalaxy.io) - The Cursor for SQL | NYC, NY | Full time -- Founding Frontend Engineer -- Founding Backend Engineer -- Founding Machine Learning Engineer

We are building the unified data platform, starting with a reimagined SQL editor from the ground up - and moving into sharing, collaboration, access controls, and more.

We just launched the alpha product TODAY to a list of over ~2,000 people on our waitlist

Myself and a handful of super deep data / SW engineers started Galaxy as a passion project to solve 3 key problems:

1. *Queries everywhere* – SQL lives in Slack snippets, BI folders, dusty Git repos, and copy-pasted Notion pages.

2. *Never-ending data requests* – because no one can find (or trust) the right query, engineers and analytics teams still get pinged for “one more pull.”

3. ChatGPT doesn’t have full DB context - non technical users are writing incorrect SQL that lacks context AND technical users are rewriting the same queries over and over again

LOOKING FOR: We're looking for high agency, high velocity individuals and someone who wants to be part of a family. We are building ~the unified data platform~ and want someone who is excited to be part of the story.

APPLY: To apply friend me on LinkedIn or shoot me an email with your profile at hello@getgalaxy.io

FusionAuth | Senior Application Security Engineer | Denver, CO, USA ONSITE 140k-200k

Our mission is to make authentication and authorization simple and secure for every developer building web and mobile applications. We want devs to stop worrying about auth and focus on building something awesome.

There are a lot of companies in the auth space, but we feel like we have something special:

* a unique deployment model (self-host on-prem or in your cloud or run in our cloud)

* A well designed API first approach; one customer compared our app to petrichor

* a relatively mature product (the code base is over eight years old and we've found and fixed a lot of the sharp edges around core login use cases; however there are plenty more features to add)

* founder-led; the CEO is an engineer who still writes code

* a full featured free-as-in-beer version that makes the sales cycle easier; prospects often come in having prototyped an integration already

If you are passionate about technology and want to join a company moving the industry forward, FusionAuth might be a great fit for you. As mentioned, our core software is commercial with a "free as in beer" version. We also open source much of our supporting infrastructure.

Technologies and standards that we use or implement: Modern Java, MySQL, PostgreSQL, Docker, Kubernetes, OAuth, SAML, OIDC.

Avy | Staff Engineer / Startup Polyglot Engineer | San Francisco or Salt Lake City | Onsite (Hybrid) | Full-Time | https://www.avy.ai

We are an early-stage, well-funded startup making humans and computers work together more efficiently. Experienced team from Apple AIML and other great companies.

We will be opening several roles soon, but are previewing this one early: Staff Engineer / Startup Polyglot Engineer.

You'll enjoy this role if:

- You like going 0 to 1 with high ownership: moving features and products from idea on a napkin, to prototype, to engineering UI, to shipped and polished product

- You are innovative, get satisfaction out of learning new things, and thrive in an environment of uncertainty and opportunity

To succeed, you should:

- Have the wisdom to know when to take the fast route vs when to step back and clean up your mess

- Be capable and excel on your own, but be humble and communicate well with others as projects require more collaboration

- Be versed across many programming languages (e.g. from C++/Java/Swift to Go to JavaScript or Python)

- Have worked on many types of projects and software -- have you built servers, written games, shipped native apps, and vibe-coded (kidding) web apps? If so, you're a fit.

- Be versatile and work both high level and low level, on old tech and new. Have you both prompt-engineered an LLM AND tweaked the code that decodes tokens in your own local LLM runner? If so, you're a fit.

All said, we're looking for the stereotypical "startup engineer" who can move between different components, be creative, be flexible, take ownership, and get things done. We have a complex, challenging product, but one that's amazing to work on and that will soon change how people think about working with each other and with AI.

Email us at jobs@avy.ai.

Phrasing.app | CTO | EU Remote

I've spent the last 18 months iterating on Phrasing, a language learning app for polyglots. It's finally reached a stable point, and we're starting to get Daily Active Users. I've been using it every day for over a month now to learn over a dozen languages, and have been blown away at my progress.

However, I've really reached the limit of what one engineer can do alone. I'm looking for someone to help me make it go brrr. Someone who would love to iterate on our in-house sync engine, make our monolithic postgres database purr, and wouldn't be scared of a little machine learning.

The product is built in Elixir on the backend, ClojureScript on the front-end. There are no experience requirements so long as you're committed, capable, and hungry.

I'm really trying to do something different with Phrasing. No investors, no hyper-scaling, no enshittification - just a relentless pursuit of mastery and a delightful product.

If any of this is speaking to you, get in touch at hackers [at] phrasing [dot] app.

Carebit | Full Stack Support Engineer (Ruby on Rails, TypeScript/JS, React, Postgres, Linux) | Fully Remote (European timezones only) | Full-Time - Up To £80k/$100k/year DOE

About Carebit

[Carebit](http://www.carebit.co) is a young, design-led healthcare technology company helping over 1500 private doctors across the UK run their practices more effectively and efficiently with our web and mobile platform, along with hundreds of thousands of their patients. For too long, medical software has been clunky, user-hostile and complicated, and we are changing that. Several customers have independently described us as ’the Apple of practice management software’.

We are a bootstrapped, profitable and remote-first company of 30 people with 6 full stack engineers including the company’s founder, Dominic. Having been remote from day 1, we fully believe in its benefits. We do have a lovely office in London by the river for in-person collaboration when required, but this is not mandatory as we know some like in-person working and some prefer fully remote!

About you

We’re looking for a Senior Support Engineer to work with our Support and Data Migration teams for day to day work troubleshooting and resolving technical customer issues. We’re specifically after someone who is curious, experienced and enjoys investigating and solving technical issues that vary from fixing simple bugs to small tweaks to existing features (e.g. adding a new column to a CSV export) to writing Ruby scripts to execute changes after a data migration to Carebit.

You’ll likely have a strong software development background already. This is a hands-on role where you’ll be regularly shipping fixes and improvements to the core Carebit platform as well.

- Strong experience with Ruby on Rails and React, especially design patterns (we use Rails 7 and Ruby 3.4 with Postgres 17, deployed to AWS ECS) - Bonus points for Linux/sysadmin and Postgres knowledge - Fluent in written and verbal English and an excellent, timely communicator - especially with customers - Self-disciplined, autonomous, motivated, and able to manage concurrent tasks

This is a fully remote role but we operate on London, UK time and so are only considering candidates in GMT/BST ±3 time zones who are willing to work to UK hours (typically 9am-5.30pm)

Please email CVs to hiring[[at]]carebit dot co if you’re interested in learning more!

We recently announced $14.4 million in funding to make blockchains & digital assets useful for the world. Founded by Jump Crypto alumni and core contributors to the Solana protocol and the Firedancer client (https://github.com/firedancer-io/firedancer), we’re tackling fundamental scalability, performance, and usability challenges in distributed ledgers. Our runtime conforms to the RISC-V specification—moving away from domain-specific VMs, DSLs, and bespoke compiler toolchains that limit developer and institutional adoption. Components are developed in C for maximal control over performance and resource usage.

Interesting problems you’ll tackle:

- Building and testing high-performance subsystems in C (cryptographic routines, consensus primitives, networking protocols)

- Designing robust process isolation on modern CPU architectures and tile-based multi-core layouts

- Optimizing memory hierarchies, cache utilization, and low-level I/O for commodity servers

You:

- 5+ years of systems programming in C/C++, Rust, or similar

- Deep expertise in CPU microarchitecture, memory subsystems, and low-level performance tuning

- Strong understanding of distributed systems design and consensus protocols

- Experience with high-performance networking and protocol design in real-time environments

Roboflow | Solutions Architects, Implementation Engineer, Developer Advocate, Full Stack Engineers | Full-time (Remote, SF, NYC) | https://roboflow.com/careers?ref=whoishiring0625

Roboflow is the fastest way to use computer vision in production. We help developers give their software the sense of sight. Our end-to-end platform [1] provides tooling for image collection, annotation, dataset exploration and curation, training, and deployment.

Over 1 million engineers (including engineers from 2/3 Fortune 100 companies) build with Roboflow. We now host the largest collection of open source computer vision datasets and pre-trained models [2]. We are pushing forward the CV ecosystem with open source projects like RF-DETR [3] and Supervision [4]. And we've built one of the most comprehensive resources for software engineers to learn to use computer vision with our popular blog [5] and YouTube channel [6].

We have several openings available but are primarily looking for strong technical generalists who want to help us democratize computer vision and like to wear many hats and have an outsized impact. Our engineering culture is built on a foundation of autonomy & we don't consider an engineer fully ramped until they can "choose their own loss function". At Roboflow, engineers aren't just responsible for building things but also for helping us figure out what we should build next. We're builders & problem solvers; not just coders. (For this reason we also especially love hiring past and future founders.)

We're currently hiring for full-stack engineers to help build our product, field engineers that work directly with our customers to solve their business needs with computer vision, and several technical roles on the sales team.

We raised our Series B round at the end of last year, led by GV. With this round, we will continue building the open source tools, platform, and community so developers and enterprises can deploy computer vision applications to production. [7]

MixRank (YC S11) | Software Engineers | 100% REMOTE (Global) | Full-Time

MixRank processes petabytes of data every month from web crawling. We have hundreds of customers using our data products including Google, Amazon, Facebook, Intel, and Adobe, across industries including Finance, Recruiting, Sales, Marketing, and Security.

We’re a fully-remote company with a global footprint in over 20 countries. We're growing, profitable, employee-owned, no dependence on outside funding. Applicants from all geographies and backgrounds are welcome.

We are looking for passionate individuals for whom programming is not just a job but it’s something they love to do. We're obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team.

Our code base is very friendly to new contributors. You'll have a fully-functional development environment within hours (fully automated) and be pushing commits on your first day. Deployments to production happen multiple times per day and finish in less than 2 minutes. Effectively all of our codebase is written in Python, Rust, SQL, Javascript/TypeScript, and Nix. The core technologies you'll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git.

We operate at a larger scale than typical startups. We operate two datacenters with high performance servers we've built that are capable of dealing with the volumes of data we process. We've implemented our own distributed file system. We do full-scale web crawls. We download and perform static analysis on the entire universe of Android APKs and iOS IPAs that are published. Unlike a typical startup where you'll spend half of your time in meetings, and the other half fixing bugs from Jira tickets— at MixRank you'll get to challenge yourself with difficult technical problems that will help you to grow as an individual.

We're hiring continuously for the positions below— they aren't singular positions that will close once filled. Our philosophy on hiring is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities that are specialized to their interests. Other companies will come up with a long list of specific requirements for a position with the expectation that you'll exactly replace someone from the team, or that you'll be the perfect tetris piece that satisfies the job requirements decided by a committee. MixRank is more pragmatic: we'll first get excited about having a unique individual on the team, then we'll figure out the best way to accommodate their specific talents.

Fullstory | Atlanta or Remote (US or Colombia) | https://www.fullstory.com/

Fullstory provides privacy-preserving session replay and analytics for websites and mobile apps. Our session replays are nothing short of magical - they look almost like a video of the user's screen (with private details redacted) - and the combination with analytics creates eye-opening insights.

We have several engineering roles open. The fullstack roles are going to be working with Go (golang), gRPC, Solr, BigQuery/BigTable, Kubernetes (K8S/GKE), and more on Google Cloud Platform (GCP) for the backend, and then TypeScript & React for the frontend.

USA:

* Senior Software Engineer, Full-stack, Application Experience - $160,000 to $190,000 - https://www.fullstory.com/careers/jobs/1a014b19-d805-4547-9a...

* Senior Software Engineer, iOS - Objective-C, Swift, Rust, and smaller amounts of other languages. This role is part reverse engineering, part systems programming, and part library development. It's about taking things apart, seeing what makes them tick, and figuring out how to get at the bits we need without negatively impacting the app experience (or using any private APIs!) Low-level knowledge of Swift and SwiftUI would be particularly helpful. - $176,000 to $207,500 - https://www.fullstory.com/careers/jobs/ab3f8ecb-ee1f-4431-a0...

Colombia:

...and a few roles in other categories, see https://www.fullstory.com/careers/ for the full list and some general info.

For the US roles, in addition to the listed pay ranges, you can expect regular raises & bonuses, equity, and benefits including: health insurance, 401k matching (Vanguard), annual learning stipend, unlimited PTO, and more. I take about 5 weeks vacation a year, in addition to ~3 weeks worth of company holidays (federal holidays + the week of Christmas to New Years.)

You also get a 5-week sabbatical after 5 years of employment - I just took mine at the end of last year, and it was fantastic.

To apply, please submit your info on the website. If you have questions, feel free to reply here or send me an email. (I'm an engineer on the iOS team, so I don't know as much about the other roles, but I'll do my best to answer questions.)

Max AI | SWE Fullstack, Backend, AI/ML Engineer | Hybrid In-Person/Remote (SF) | Full-time | $145k — $230k | https://www.maxcare.ai

Max AI is building the financial operating system for healthcare—turning the broken, error-prone billing process into a lightning-fast, autonomous experience, much like swiping a credit card. Our ambient AI agents handle medical coding, claim submission, and fund collection the moment a doctor finishes charting—no humans in the loop.

We’re addressing a $350 billion market where billing errors cause delayed treatments, higher healthcare costs, and massive medical debt. By eliminating billing mistakes, we enable faster access to care, reduce administrative burden on doctors, and protect patients from surprise bills.

We're a team of repeat founders and world-class builders:

- PhD/Postdoc AI scientists from MIT and Caltech

- Ex-VP of Engineering at Curative (led engineering for over 25M medical claims billed)

- Founders who’ve scaled products to 40M+ downloads and 150M+ monthly users

- A team of experienced engineers from Discord, Google, Facebook, Airbnb, Brex, and Figma

Traction:

- Launched in 2025

- Projecting $5M ARR in the next 2 months

- $2M in claims processed in the first 30 days (we earn 4–12% per claim)

We're 6 months in and just getting started. If you want to help build the AI infrastructure that will transform healthcare finance, reach out to: colton[@]maxcare[.]ai or apply at https://app.dover.com/apply/Maxcare/3684f186-f343-439a-9500-...
