Be the careful eye behind our AI safety research. Prague (on-site) • Part-time We're a deep-tech AI safety stealth startup. We make powerful AI systems safe to deploy, a problem that gets more urgent as AI becomes more capable and autonomous. Backed by leading investors, with IOI/IMO medalists, top-university PhDs, best-paper winners, and advisors holding top prizes in CS and AI, including a Turing Award holder.

It's focused, detail-heavy work, and it suits someone who enjoys getting things exactly right.
