We're four people. You'd be the fifth, working with me, the founder, in SF.

The product is a training coach that adapts to how an athlete's body and life are actually going. You'd work on the coach itself: route planning, goal setting, and the recommendations it makes day to day. Go try the route planner at imperfect.co/routes. That's the shape of the work: the reasoning, the wearable data behind it, the evals that catch it being wrong, and the latency that makes it feel like a conversation.

Python, FastAPI, Postgres. You'll be releasing to prod from the first day.

Coding agents write most of the implementation, so the job is deciding what to build, breaking it into pieces an agent can execute, reviewing the output, and proving in production that it works. You should already use Claude Code, Codex, or Cursor daily, have views on getting production-grade output from them, and be able to tell when one is wrong. You should love coding and love building even more.

0 to 3 years, new grads fine. We want builders, and we read for three things. Smart: you got into a school that was hard to get into for what you studied, and you did well there. Weird paths count: I started at community college. Hard working: you shipped product at a startup, or built something people actually use on your own. Curious: you try new things before they're proven. We want people who are already living in the future, and that comes from personality more than anything on a resume. By month three you're deciding what the coach does next and answering for it in prod.

San Francisco, in person two or three days a week. The rest of the team is in Mexico City. Salary and equity are above. Equity vests monthly over four years with a one-year cliff.

I'm an ultramarathoner who previously started and sold two companies backed by investors like a16z and Stripe. I also built the most used open source project to pull Garmin Health data with over 350k downloads / month on PyPi and used by Stanford Health.
