Great performance is critical to Apple's product experience, but exceptional performance begins with the decisions we make today about the products of tomorrow. The Performance Modeling and Features team within CoreOS Performance serves as performance optimizers and strategic advisors across Apple's software and hardware organizations, using performance analysis, data-driven insights, and predictive modeling to improve performance, as well as shape architecture decisions, hardware specifications, and product planning. The team is seeking an engineer to focus on AI feature performance and can operate at a unique intersection: using performance expertise, data science, and strategic planning to not just measure and optimize performance, but model it, predict it, and use those insights to shape decisions. If this excites you, we should talk!
In this role, you'll serve as a performance optimizer and advisor with a focus on AI feature usage on our platforms, working with everyone from feature teams architecting new capabilities to hardware teams planning next-generation devices. Your goal will be to ensure Apple ships smooth, snappy, and efficient AI features and the best possible customer experience for the system as a whole. You'll write code for feature optimizations and testing automation, as well as analysis pipelines and simulation tools that enable teams to make informed decisions based on quantitative insights.
