Applying for something else? Pick the speculative option at the end.

A link rather than an upload, so nothing of yours sits on our servers unnecessarily.

We would rather read four honest sentences than a cover letter.

We reply within one week, either way.

What we look for

  • Five or more years building production software
  • Shipped at least one LLM system that real users depended on
  • Comfortable arguing about evaluation methodology
  • Writes clearly enough that a client can read the design document

Not every line has to be a yes. Apply if most of it sounds like you.

What happens next

  1. 01A 30-minute conversationWith someone you would actually work with. No recruiter screen, no take-home before we have spoken.
  2. 02A paid work sessionFour hours, paid at contractor rate, on a problem close to real work. You keep whatever you build.
  3. 03A deep-dive on your craftNinety minutes on something you have done before. We ask about the decisions and the parts that went wrong.
  4. 04A decision within a weekOffer or not, with written feedback either way. We have never taken longer and do not intend to start.

We pay for the work session at contractor rate. Asking for unpaid labour from someone who already has a job is not a fair trade.
