We are hiring full-stack and applied AI engineers, as well as a UI designer, for in-person roles in NYC.

We are a seed-stage start-up, still in stealth (but already with an acquisition offer!), backed by tier-1 VCs and many of the most prominent experts in legal technology. We are working with several of the best law firms in the world. We have strong customer demand and need people to help us fill it. We are committed to improving access to justice.

We are hiring a small team of extremely talented, motivated, intense, and interesting people to solve the most difficult and important problem in legal tech: high quality answers to legal questions. Expect market-leading compensation, including meaningful equity ownership. Please send your resume to contact[at]ashmere.com.

Aquabyte | USA | Full-Time | Perception Engineer | Platform Engineer | SF HYBRID and REMOTE

Aquabyte is on a mission to revolutionize the ocean sustainability and efficiency of aquaculture. By making fish farming cheaper and more viable than livestock production, we aim to mitigate one of the biggest causes of climate change and help prepare our planet for impending population growth. Aquaculture is the single fastest growing food-production sector in the world, and now is the time to define how technology is used to harvest the ocean for generations to come. Through custom underwater cameras, computer vision, and machine learning we are able to quantify fish weights, detect sea lice infestations, and generate optimal feeding plans in real time. Our product operates at three levels: on-site hardware for image capture, cloud pipelines for data processing, and a user-facing web application. As a result, there are hundreds of moving pieces and no shortage of fascinating challenges across all levels of the stack.

One of our customers has thousands of packaging assets spread across dozens of markets, languages, regulations, and brand standards.

We are automating it. The challenge isn't generating text. The challenge is building systems that can be wrong almost never.

We're looking for:

- Forward Deployed Engineers who enjoy sitting with customers, figuring out what's actually broken, and building solutions faster than a roadmap ever could.

- Applied AI Engineers who obsess over retrieval, evaluation, orchestration, reliability, and all the ways AI systems fail in production.

Small team. Real customers. Revenue. Lots of difficult edge cases.

Anyfin | Full-Stack, Backend (Go), Data Engineer | Stockholm, Sweden | ONSITE 3 days/week | Full-time | Relocation + visa sponsorship

What happens when you get a number wrong?

In most systems, you log an error and move on. At Anyfin, a wrong number is someone's loan application.

We're a profitable Swedish fintech that helps people refinance expensive consumer loans at better rates. Small team, regulated industry, which sounds like a recipe for slow, cautious engineering. It's the opposite. The regulation sets the floor, not the ceiling. Above that floor, we experiment, ship, break, learn, and ship again.

We're building real-time credit decisions using ML models on GKE, Go and Python on the decision layer, TypeScript/Node.js on the API, React on the frontend, BigQuery and dbt for data. Interesting stack, interesting problems, and because we're small, you're close to all of it.

Our co-founder Sven is back leading eng and hiring directly. No recruiter chain, no committee. Short feedback loops. Real ownership. No one to hide behind.

Roles: Senior Backend · Full-Stack · Cloud · Data Engineer
