Sarama | Canine Language Specialist | On-site (San Francisco, CA) | Full Time | Must have a dog | praful@sarama.ai

Company: We’re building smart collars and devices to decode dog communication—using audio, motion, and behavior data. Our goal is to understand what our dogs are trying to say and rethink the worlds of training, healthcare, and companionship as we uncover their language. We've trained models for dog vocalizations and movement patterns, and now we’re integrating behavior and intent.

Role: You’ll work closely with our engineering team to help ground our models in real-world behavior. From structured training sessions to experimental communication techniques (e.g. dog buttons, symbolic vocalization training), your work will directly shape how our devices interpret canine communication. You'll guide the design of training protocols, data collection, and help teach dogs how to speak using structured methods.

You:

+ Experience in dog cognition, vocalization, and training techniques.

+ Familiar with AAC devices or button-based communication systems.

+ Scientific mindset with hands-on experience.

+ Passionate about language and cross-species understanding.

+ Must have a dog (ideally one you’ve trained using vocal cues or buttons)

Apply: Send us an email with a video or write-up of your past work (bonus if it includes your dog using buttons or vocal cues) to hello@sarama.ai with subject: “{Your dog’s name} wants {something they want}.” In the body, tell us what interspecies communication means to you.

If you refer someone to us, tell them to let us know and we'll send you a gift! (we aren't able to give a cash bonus just yet soon though)

Pursuit | Full‑Stack & AI Engineers | Ann Arbor (MI) / Los Angeles (CA) / Remote (US‑only) | Full‑Time

Look at the latest government‑tech headlines and you’ll find our customers. Pursuit (https://pursuit.us) is using AI to fix one of America’s costliest, most overlooked problems: the painful process of selling to 109 000+ state and local agencies. We turn budget PDFs, board‑meeting transcripts, and financial reports into structured insight so the best vendors—not just the best‑connected—win.

About Pursuit Founded after our previous founder's company exited for $200 M; 15 months in with clear product‑market fit.

Trusted by: OpenGov, Flock Safety, Wiz, Granicus, Qualtrics, NeoGov and 50+ other top GovTech/SLED vendors.

Backed by: Jack Altman, Blake Robbins, Bill Gurley, Sam Hinkie, AI Grant, and angels behind OpenAI, Rippling, Airtable, Anduril.

Why We’re Different: Deep signal – we mine every public document others ignore. Compounding data loop – more FOIA data → better models → faster wins. System‑level rethink – we’re not optimizing the old process; we’re rebuilding it. Real traction – Pursuit is the default tool for vendors tired of surprise RFPs and incumbent lock‑in.

What We’re Looking For:

* Engineers who want to die knowing they made the country better.

* People who enjoy weird, high‑scale data problems.

* Builders willing to chip away at a system everyone else gave up on.

Apply at https://pursuit.us/careers or email us directly at careers@pursuit.us (mention “HN Who’s Hiring”).

Phosphor | NYC | Full Time | Founding Engineer (HCI focus) | $175-225k + Equity

Phosphor enables the development of the built world (e.g. from real estate to energy projects) to be managed agentically by building programming languages and observability primitives (like version control) on top of a hypergraph.

Our primary technical bet is that if you capture annotated "diffs" of user information with the appropriate annotation, you can create path-dependence to train AI models in an AlphaGo like context. By doing so, we achieve agentic experiences for markets that have never even had an opportunity to imagine what life would be like with basic observability.

Our product is similar a combination of Linear and Wolfram, with components and objects that enable advanced financial modeling, legal/regulatory analysis, and geospatial analysis of infrastructure development opportunities.

We're in stealth, but recently venture-backed by one of the best deeptech funds in the market. We're hiring for a few roles at the senior/staff levels: 1. HCI Engineer - You're a prosemirror wizard who probably follows Ink & Switch or the UCSB HCI lab on Twitter; front-end/rich-text/typescript focused; lots of architectural/sync engine work 2. Systems/Compiler Engineer - We design and build dev tools for languages we create that compile into various graph representations. These range from financial modeling calcs (which need to go very fast to support a seamless UX), to computable representations of legal agreements. Extra points if you've worked with hypergraphs. This in Rust but we're exploring a few other languages.

Email resume/linkedin/twitter to oliver@phosphor.co if you might fit somewhere in here, or if you've taken a credible attempt at building end-user programming tools.

You either trust the “founding” candidate to be a founding engineer and therefore trust their judgment or you want a regular engineer to continue with whatever jank the founders hacked together and the “founding” title is meaningless.

Lore (https://careers.lore.co) | Software/Machine-Learning/ Data Engineers + More! | Full-time | REMOTE (US)

The company: Modern healthcare excels at treating fallout, but it struggles to address triggers—because it wasn’t built to. Yet intervening at these trigger points isn’t just how we stop rising demand; it’s how we create more health and happiness. We started Lore to build a new kind of care: a continuous, holistic approach that supports people whether they’re flourishing, struggling, or somewhere in between. We call it preemptive care.

The role:

- Small, cross-functional squads that own the full vertical slice of a problem space.

- No product or project managers—you're the one driving decisions and implementing them in a fast-paced, ambiguous environment.

- Working fully remote across the US means you need strong written communication and the ability to work asynchronously. Whether you're deep in technical details or connecting ideas across disciplines, clear communication is essential.

- We value the expertise you bring, but when new information comes along, we also need you to adapt quickly, challenge old assumptions, and embrace new ideas.

- If you thrive in an environment that rewards bold ideas, continuous learning, and active engagement in every aspect of the business and want to help people become more agentic, Lore might be the perfect place for you.

Edlink | Software Engineer (Front/Back/Fullstack) | Onsite (Austin, TX) | Full-time | $150k–$180k + Equity

Edlink is a small, high-performing team building the data infrastructure that powers edtech. Our API helps 60M+ students and educators access the software they need to teach and learn. We solve hard problems — messy school data, ancient SIS platforms, massive scale — and we do it without red tape, meetings about meetings, or fluff.

We’re 23 people, all in on building fast, owning our work, and helping each other grow. We believe in high trust, deep work, strong opinions (held loosely), and building great tools that actually help people. No micromanagement. No bureaucracy. Just a team of sharp, kind engineers shipping great code and pushing each other to improve.

The role: You’ll work across our stack (TypeScript, Node.js, Postgres, Kubernetes, Vue 2/3), building powerful APIs and clean UIs that help integrate thousands of school systems. You’ll also work directly with developer clients who use our API — think Stripe for edtech.

Perks: Equity from day one, unlimited PTO, free downtown parking, paid parental leave, relocation support, and weekly team lunches.

We’re in-person in Austin because we believe startups build better products — and have more fun — when they work side by side.

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.

Phaselaw | San Francisco | Hybrid | Full Time | Founding Product Engineer

We're a Seed-stage legal tech startup working to eliminate manual doc review, the most hated part of every lawyer's early career.

Our founding team is highly experienced (I was CTO of a large analytics company through its successful exit; our CTO was a Staff Data Engineer at Reddit and his two prior companies had successful exits; our COO was the COO of an MIT Media Lab spinoff and head of product at a number of early stage startups). And although it's very much the early days of the business, our product is the best in the world at its particular niche and we already have about 20 paid customers including legal teams at some of the largest companies in the world.

We're looking for someone who is focused on the frontend (NextJS) but can flex across the stack — it would be delightful if you were comfortable dropping into the backend (Python/FastAPI/Postgres/EKS) and even more delightful if you were comfortable making design decisions since we're early enough we don't have a designer on staff. More important than any particular technical skill, we're looking for someone who has a strong product sense and is motivated by customer problems, who has strong accountability, and who is excited to be hire #2 at a rapidly growing company with all of the chaos and opportunities for growth that come with that.

If you're interested or have questions, drop an application here: https://jobs.ashbyhq.com/pear/361caae7-d798-4603-b428-4ca959... or feel free to email me at josh+hn@phase.law

Purplefish | https://purplefish.com/careers | Member of Technical Staff | Full-Time | ONSITE | New York, NY, USA | NextJS, Typescript, Python | $150k-$225k + 0.5%+

Purplefish is transforming the trillion-dollar talent industry with powerful AI agents that will fully automate most hiring processes end-to-end.

We are funded by 8VC, and Adam and I previously worked closely together to launch 145 companies at the venture studio Fractal Software out of a $650 million fund. Before that I was a staff software engineer at Lyft, and Adam was CRO at Wunderkind ($100m+ ARR). We've built a powerful voice agent, and are expanding into other parts of the sourcing-to-onboarding flow. We have customers, revenue is growing, and so is our team.

We're currently a team of 3 engineers in NYC (9 people total). We're working on really cool problems with multimodal AI agents (and some really not cool problems like ATS and HRIS integrations). I'm trying to build the engineering team that I would want to join, which to me means a high emphasis on agency, purpose, technical excellence, collaboration, learning and velocity. Recently A16Z mentioned us in the state of voice AI report: https://a16z.com/ai-voice-agents-2025-update/

We're building on LiveKit's agents framework, Python, and NextJS. We're having a lot of fun and having real positive impact on our customers' businesses.

Unitary Foundation | Full-Stack Web Developer (UI/UX) | Open-source | Full-time | Remote (EU/NA timezones) | https://unitary.foundation/

We're a quantum computing non-profit organization, and we are looking for a web developer.

The job is classical — mostly building web portals — but those portals open into the quantum world.

Quantum computing knowledge is a plus, but not required. The initial project is a platform to understand the trajectory of quantum computing. The focus is on data visualization, so strong skills in that area are preferred. The candidate will work mostly alongside quantum engineers and researchers, so ownership to work independently on the classical side of things is important.

The stack of the main web project is PERN, but the organization maintains other projects in Python.

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.

You'd be a great fit if you have:

- 5+ years of software development experience

- A strong track record in high-scale backend development

- Experience with cloud infrastructure

- Solid front-end skills

- Strong communication skills and a collaborative mindset

We offer competitive salaries, top-tier equipment, great offices, and a team that genuinely values your input.

Attendi | Senior Frontend-Focused Full-Stack Engineer | Amsterdam, ON-SITE hybrid | Full-time (80-100%)

Healthcare professionals have to spend too much time on administrative tasks when they should be spending that time delivering great care. Attendi allows healthcare professionals to report with their voice. This saves them precious time and removes the screen between client and caregiver, allowing more personal and effective care to be given. Burdened by an aging population, the healthcare sector is in desperate need of innovators like Attendi. We feel that we provide an extraordinary work environment: getting paid well to work with smart people on things that actually have a positive impact on society.

Attendi has built a strong user base with its API-first speech-to-text solutions and client SDKs, loved by healthcare professionals via integrations with electronic health record (EHR) vendors. Currently, users interact with our products only within their EHR systems — but why stop there? We want to enable them to benefit from our tools anytime, anywhere.

As a Frontend-Focused Full-Stack Engineer, you’ll play a key role in developing our new (greenfield) products to support this ambition:

Attendi’s first external full-stack app — which we see as the healthcare sector’s notepad. Our aim is to make it the default write-layer for medical data. But it’s far more than a simple notepad: speech-to-text and machine learning will be deeply integrated.

We have a dedicated team with fewer than 25 members, which means no bullshit, moving fast, and getting a generous slice of equity. We're post product-market fit, profitable, and on the cusp of scaling up in the Dutch market.

Check out https://attendi.recruitee.com/o/senior-frontend-focused-full... for more details on the position.

Feel free to send any questions to berend [at] attendi [dot] nl.

FusionAuth | Senior Security Engineer, others | Denver, CO, USA ONSITE (other positions are remote as) | Salaries listed on job req, but for the Security Engineer it is 140k-120k

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.

We are profitable but raised a round in 2023 to accelerate our growth (more on that here: https://fusionauth.io/blog/fusionauth-funding ).

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

Raileasy | Junior Backend Software Engineer | Remote (company based in London) | Permanent/PAYE | Must be UK Based

Ever wanted to work in the UK rail-ticketing retail space?

Raileasy, who own and operate the TrainSplit brand, are hiring for a junior backend software engineer.

Our API powers some of the most established and recognisable brands in the independent rail retail space (particularly where split-ticketing is involved) such as TrainSplit, Realtime Tickets from Realtime Trains, Split My Fare, Railboard and others. We provide both B2C and B2B ticket booking services. We are a remote-first organisation; we have engineers in a variety of locations across the UK, but we make good use of pair programming, video conferencing, asynchronous communication and in-person meet-ups at mutually accessible locations to collaborate.

We’re looking for someone UK-based who will be able to work on our .NET-based services, primarily in C# – but we have a variety of smaller services written in languages like Golang and Rust too. This role would be ideal for someone who has recently graduated from e.g. a CS course, or has taught themselves how to program and now has a decent grasp on the fundamentals. Any internships, placement years and/or open source contributions/repositories (even if it's just a few Advent of Code days) you could show us would reflect well on your application.

An interest in public transport/rail would be a plus, but is by no means a requirement.

For more information about the role and our API’s architecture, please see https://raileasy.co.uk/careers and the full specification at https://raileasy.co.uk/backend-engineer

For questions send us an email to careers AT trainsplit.com. To apply, email a copy of your CV to the same email address.

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.

n8n | Senior AI PM | Remote (Europe timezones) | Full time | niklas@n8n.io

We're looking for an exceptional AI Product Manager to join us at n8n, and in my (biased) opinion this is a once-in-a-lifetime opportunity. n8n is a fair code AI workflow automation for technical teams. It’s not just a place with a great culture, but is also seeing crazy growth right now: - We 5x’d our ARR last year, and are on track for a much higher multiple this year. - Every week, 100k+ new users try out n8n. - We have a fanatic community that absolutely loves the product.

We're right at the center of defining how people will build with AI in the coming years. But to truly lead this very competitive space, we need someone to tackle the massive challenge of define n8n's core AI strategy and execute the roadmap that makes us the undisputed default tool for AI building. That's where you come in.

What we’re looking for (the unicorn) - Great PM skills: You thrive in high-pace, high-uncertainty environments, can prioritize the most important things from a long list and ruthlessely focus on what’s important. You should also be technical and able to empathise with our technical user base. - AI Native: You bring a deep, nuanced understanding of the modern AI landscape, are well connected in the AI space (part of the "inner circle," know the key players/research) and have informed opinions on where the market’s heading - Humble & passionate: You bring a deep passion for product craft and making an impact. You’re humble, authentic, radically transparent but yet have strong convictions and can stand your ground.

Important: We only hire in Europe timezones, so you either need to live here or be willing to relocate.

We know this is a rare combination and a demanding role with incredibly high expectations. You'll be shaping the future of AI development for potentially millions of users.

Maritime shipping software | Full-stack software engineers | UX Designers | Implementation Managers & Customer Success execs | Data analysts | Global REMOTE | UCT-8 to UCT+4

Would you like to help tackle one of the most important sectors for the global economy - maritime shipping? We're hiring for multiple roles: software engineers, data analysts, UI/UX designers, implementation managers.

Nearly every person is affected by stuff shipping on the seas - whether its energy, ore, or wind turbines, but the industry itself is antiquated and archaic, and hampered by paperwork and bureaucracy. Our customers are crying out for better solutions. We're looking for people to help us build those solutions.

If you're the sort of person who is: - intellectually curious about new industries - wanting talking to and getting close to end users - keen to use LLMs and other AI tools

Then please get in touch.

--

For our SWE roles we have budgeted ~ 90k USD.

Our tech stack for new projects is largely typescript/vue/mysql (we have several fans of fp-ts and EffectT with us and are investing in using more functional programming). But like the industry at large we also have significant legacy code in javascript. If you're the sort of person who likes refactoring complex projects to make them more workable, then we also want to hear from you.

--

For our Data Analyst or Implementation Manager roles:

You'll be helping our customers in maritime shipping get the most from our software. Initially, a lot of that work will be in helping our customers get their data in and out of it. Lot's of MySQL, Metabase, AWS Glue, DBT, or other ETL pipelines.

--

For our UI/UX designer roles we have budgeted ~ 40k USD.

You'll be helping us on three different axes: (1) designing the user interface for new features, (2) fleshing out the user journeys and mockups for our roadmap, and (3) helping us craft a consistent and learnable user experience across all our software.

--

We hire remotely and globally with offices in Houston, London, Singapore, and Joinville (Brasil). You should be fluent in English. The current team is >20 people. You should be in a timezone within 3 hours of one of those offices.

Interested? You can contact me directly from my profile. I'm the CTO.

Please, no recruiters or agencies.

ko-br | Chief Commercial Officer (CCO) | Europe/London (preferred) | Equity + Leadership Role

We’re ko-br – a London-based AI robotics startup on a mission to end the "3AM cobot meltdown" in warehouses. Our robots handle real-world chaos (grip slips, conveyor jams, dust storms) through:

* No-code AI that plugs into ABB/KUKA/UR arms

* Self-recovery protocols proven to reduce emergency calls by 85%

* Human-taught systems that turn warehouse teams into robot mentors

Why This Matters

Industrial robots keep failing when faced with mixed SKUs or shifted pallets. We’re fighting this $35B conformity crisis (see manifesto) by building robots that adapt to humans – not the other way around.

We Need You If You’ve…

* Scaled commercial ops in industrial tech/robotics/AI

* Closed 6-7 figure deals within the logistics space

* Built partner ecosystems around OEMs like ABB/KUKA

* Crave building vs. babysitting (this is hands-on founding role)

Founding Team

* Founder: Ex-Amazon/Meta ML engineer, expertise in ML infrastructure, computer vision, distributed systems, and building Internet-scale ML pipelines.

* Team: 40+ years combined expertise in VR, ML, robotics, MLOps, data annotation and cybersecurity

Apply

Railway | Product Eng (full stack), Developer Relations, Infra (Platform) eng, Infra eng - Data Centers| REMOTE (International) | https://jobs.ashbyhq.com/Railway?utm_source=DayMzWzJ0P

Tired of trying to beat kube into shape? Does writing YAML to ship code fill you with utter dread? Dream of a future where deploying software is simple, and you don't need an army of infrastructure engineers to build that perfect janky bash script™ to make life easy?

We're Railway, and we think infrastructure can be better. So far we've built out a platform loved by hundreds of thousands of users who simply tell us "Give me Postgres", "Deploy this repo", and we make it happen

Fair warning! The problems are complex: home-rolled hypervisors, cut-above container orchestration, over/under/whateverlay networks, virtio device drivers, edge proxies, IAM that doesn't suck, kitchen sinks - we need to build it and we're looking for likeminded individuals who think this stuff is fun.

Four open roles (apply below!):

Chorus One | https://chorus.one/careers | Platforms Engineer | REMOTE (Switzerland ± 6 hours)

Chorus One operates validators on many proof-of-stake blockchains (the ones where security is based on a Byzantine fault-tolerant consensus algorithm rather than wasting energy). We are hiring for several roles, but the one I will highlight is what we call Platforms Engineer. Some companies call this Site Reliability Engineering or DevOps.

The main thing we do is take upstream software, build it, run it on our infrastructure, and then monitor it and optimize that setup. Some things that make this interesting are:

    * Building automation that enables us to do this for many networks (70+ currently).
    * Doing this with high uptime, building automation for failover, etc.
    * Working with software that is on the one hand cutting-edge and doing interesting things (consensus algorithms, distributed systems, cryptography), but on the other hand that means it’s immature and often not easy to operate and monitor. Often we have to build custom tools, and dive into the source code of the project. We contribute patches upstream when it makes sense.
    * Some of these projects are exercising the limits of what a machine can do, we have to do some low-level investigation that requires understanding of what the Linux kernel and network hardware are doing to properly identify what’s going on.

A recent example of what I personally find fascinating: last March, Ethereum’s Holesky testnet experienced loss of liveness. This is a real-world, globally distributed system that implements Byzantine fault tolerance, with multiple independent implementations of the protocol. Several of these implementations had a bug in an update, which caused a split in the network. The protocol is designed to handle this situation in theory, but in practice it is triggering previously unexplored failure modes in the implementations, that are hard to test for in synthetic small-scale tests. I think there are very few places where you get to be involved in a planet-scale distributed system exhibiting “interesting” behavior, especially one that is not in control of a single entity. Of course, there is also the less fun part that the testnet was broken, alerts are firing, and it was hard and chaotic to coordinate a fix when the network is not controlled by a single entity. Fortunately it’s a testnet.

We’re looking for platforms engineers and software engineers to help build the automation, but also to dive into the node software of the blockchains we validate and see if there are opportunities for us to outperform the rest of the network; Rust experience is valuable there.

Felt | Growth Product Manager | Oakland, CA | Full Time | https://felt.com

Felt is building a cloud-based geographic information systems (GIS) solution and have hundreds of customers already using it to run their operations, processing terabytes of data. Our team hails from Uber, Google, Meta, CARTO, Mapbox, The New York Times and a few others. If you have used online maps in the past few years, you have used their work. My co-founder and CEO, Sam, is a former YC founder who sold his previous company [1] and I'm an early Uber engineer.

For the first time, we are hiring a product manager that is going to be focused on our growth funnels within our service. This person will own the onboarding journey and help those first-time customers become loyal users. This role comes at a special time where we have launched a brand new version of our SDKs and APIs where customers, especially in large enterprises, can fully integrate Felt into their own tooling [2]

Ideal candidates will have 4+ years of experience focus on growth and onboarding within B2B SaaS and/or PLG companies. They will have a proven track record, own metrics such as time to value, be comfortable owning touchpoints, and designing and running experiments.

As mentioned, this role is the first product role at our fast growing company and will have strong leadership potential. You'll be joining a team that's build groundbreaking tools before, and is on the cusp of doing it again.

We are well-funded with a long runway and a strong revenue funnel already. You can read more about it our first funding here [3], and our announcement here [4]. Our terms are employee-friendly terms such as early exercise, a 10-year exercise window and even a matching 401(k).[5]

If you are interested, please reach out via hello@felt.com and mention HN and the role you are applying to. This role is based in SF Bay Area, in our Oakland office that's right next to the BART station. [6]

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.

Toolhouse | Software Engineer (Fullstack) | Onsite (Austin, TX) | Full-time | $180k + Equity

What if you built a product that helped thousands of engineers build AI features and AI agents? That is what we do at Toolhouse.

We are a high performance team working in the "infra/backend" horizontal space. We are building the infrastructure that powers AI products and agentic workflows.

We're building a team of special people that want to win in Austin.

We are looking for engineers who are excited to do great work. - Engineers who trust their instincts and who also love to discuss ideas and write them down. Humans invented writing, and built the future. - People who enjoy building developer tools that can really help other developers.

No BS attitude. Just engineers shipping code and having a good time doing it.

The role: You’ll work across our stack (TypeScript, Python, Postgres, Docker), building powerful backend and frontend for a population relying on function calling infrastructure, RAG, evals, and tons of data (prompts).

Perks: Equity vesting from day one, unlimited PTO, lunches, a real family outside of your own.

We’re in-person & in Austin. We do not sponsor visas.

We don't want your resume, show us what you shipped on Github - send it via email to our toolhouse.ai inbox: hello@...
