AI Engineer (Lex)

AIFull-timeRemote£150,000

Make Lex, each side's private assistant, draft, explain and redline contracts well, and prove it with evals.

What you'll do

  • Build how Lex drafts from one sentence, explains every clause in plain language and proposes faithful redlines.
  • Write the evals: is the explanation right, is the redline faithful, does it stay neutral to both sides?
  • Keep Lex private to each side. It drafts and explains; it never sends or signs.

Who you are

  • You've built and measured LLM features in production, not just demos.
  • You'd rather write a good eval than a clever prompt.
  • You know how to make models fast, cheap and reliable at scale.

What we offer

  • Pay stated up front on every role. No negotiation games.
  • Fully remote. Work from wherever you do your best work.
  • Real ownership of a whole part of the product from day one.
  • Work directly with the founder. Short loops, no layers.
  • We build in public, so your work is seen.
