Apple's Performance Modeling and Features team, part of CoreOS Performance, is hiring a full-time, on-site engineer in Cupertino at mid level to work on AI feature performance. The role sits between performance engineering, data science and strategic planning: measuring and optimizing performance, building models that predict it, and using those results to inform architecture decisions, hardware specifications and product planning. The posting asks for performance expertise and data science skills. Distinctive: the team acts as an internal advisor shaping hardware and product roadmaps, not just tuning code.
