Senior Agent Evaluation Engineer, AI Evaluation Platform

Join Apple Services Engineering to define how we measure whether AI agents actually work. We are seeking a senior engineer who has built agents and knows how to evaluate them rigorously. You will design evaluation suites, build and validate judges, and ship agents on our evaluation platform, so the platform is shaped by real use and not guesswork. You will partner with researchers, product teams, and platform engineers to turn evaluation methodology into tools other teams can adopt. We are looking for builders who move quickly, iterate in the open, and can tell a trustworthy evaluation from a theatrical one.
