About the Role You'll join a genuine 0→1 team on the ground floor of one of the company's biggest new bets. You will work full-stack on long-horizon agents, ship features that do real audit work, and work alongside practitioners.

We're hiring across all levels and will calibrate during interviews based on scope and demonstrated experience.
