Product Engineer

Most of our code is written by agents. The job is deciding what to build, decomposing it so agents can execute well, and reviewing what comes back with enough judgment to catch what's subtly wrong.

We care far more about how quickly you can go from idea to working, reviewed, shipped product than about which frameworks you've memorized.

This is a frontend-leaning full-stack role. You'll live in the frontend and own it, but you'll be comfortable following a feature into the API layer, the database, and a migration without waiting for someone else.

A track record of shipping real products that real users depend on, and the war stories to go with it

Fluency driving coding agents on non-trivial existing codebases, not just greenfield demos — plus the judgment to review generated code critically, catching the plausible-but-wrong, the insecure, and the unmaintainable

A clear view on where agents should not be trusted, and why

Visual craft — your interfaces look considered, and you can tell the difference between shipped-and-fine and actually good. Comfortable working from a Figma file or from nothing

Strong product sense: you make UX and technical tradeoffs deliberately, and can explain them to people who don't write code

Excellent debugging instincts, wherever the bug turns out to live

Comfort with the ambiguity and pace of an early-stage lab — loose requirements, shifting priorities, and nobody to tell you what to do next

Experience with React, TypeScript, and Next.js (we use them - we just don't think they're the hard part)

A track record of building developer tools or creative applications

Previous experience building interfaces on top of generative models, and working knowledge of AI/ML concepts

Instrumentation and experimentation experience: analytics, A/B testing, activation funnels

Contributions to open-source projects

Expect to build something live, on your own machine, with whatever tooling you normally use. Using coding agents is encouraged rather than merely tolerated - we want to see how you actually work, not how you perform without your tools. The process is four conversations plus a half-day onsite in Freiburg, and we cover travel. We'll share the full process upfront.

We’re a distributed team with real offices that people actually use. Depending on your role, you’ll either join us in Freiburg or SF at least 2 days a week (or one full week every other week), or work remotely with a monthly in-person week to stay connected. We’ll cover reasonable travel costs to make this possible. We think in-person time matters, and we’ve structured things to make it accessible to all. We’ll discuss what this will look like for the role during our interview process.

Obsessed . We are a frontier research lab. The science has to be right, the understanding deep, the product beautiful.

Low Ego . The work speaks. The best idea wins, no matter who said it. Credit is shared. Nobody is above any task.

Bold. We take the ambitious bet. We ship, we do not wait for conditions to be perfect.

Kind. People over politics. We treat each other with genuine warmth. Agency without empathy creates chaos.

If this sounds like work you’d enjoy, we’d love to hear from you.
