About The Position

The Siri Agentic Evaluation team builds software platforms and tools to define, measure, and report Siri quality and effectiveness. The team applies agentic technology to produce rich, comprehensive, and reliable feedback signals throughout the software lifecycle, from coding through qualification of new features for release. The Senior Software Engineer will build platforms and agents that help teams across Apple understand, improve, and ship the next generation of Siri. The work will inform whether Siri features are ready to reach customers. The role includes designing and building a platform for running agentic evaluations of Siri at scale, integrating evaluation signals into CI and release qualification, and building CI automations to exercise Siri across devices and features and judge its behavior. The engineer will partner with ML, product, and quality teams to define and measure Siri quality, lead technical design, and raise engineering standards through code review and mentoring.
