Siri, Eval Architect Engineer

Do you want to define the architecture of the systems that measure Siri's quality across every platform, every locale, and every model update? Apple's Agentic Eval Engineering organization is building the evaluation infrastructure that determines how Siri's quality is measured, trusted, and improved — spanning large-scale automation on real devices, model-in-the-loop simulation, AI-powered auto-evaluators, and closed-loop agentic fix pipelines. We are seeking a senior Eval Systems Architect to own the end-to-end technical vision and system architecture across our entire evaluation stack, ensuring that we build toward a coherent, scalable, and trustworthy system.
