Brex is hiring a product engineer to build the workflows, UI, and data contracts that make its agentic Audit Agent trustworthy and usable for real financial reviewers. Expect deep questions on shipping across the full stack, designing feedback loops for a non-deterministic system, and owning ambiguous product surfaces end-to-end.
