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.
