About The Position

The CPU Platform Architecture team exists to push the limits of power-efficient CPU performance. We are a tight-knit group obsessed with squeezing every drop of performance out of every milliwatt, bringing together deep expertise in microarchitecture, ISA definition, performance modeling, power modeling, and workload analysis. We’re looking for a highly motivated and innovative Embedded CPU Architect to join us. In this role, you’ll drive performance and efficiency optimization and explore architectural features for Apple’s embedded CPUs that power critical functions across Apple’s entire product line. As an Embedded CPU Performance Architect, you will help define CPUs that are specifically designed for running embedded applications across iPhone, iPad, Mac, and many other Apple products. Your focus will be to seek out areas for improvement in the unique constraints of varied embedded use cases, and model solutions that balance performance, power efficiency, and area. To do this you will collaborate with experienced CPU designers in micro-architecture and RTL to assess the feasibility of ideas through modeling and refine those ideas to make them implementable. You will also correlate RTL with the CPU performance simulator to ensure that the design meets targets and that the model is accurate. The role requires the analysis of specific workloads across a wide variety of existing and new product categories to identify bottlenecks and opportunities for improvement. We collaborate as a larger CPU architecture and performance team to maintain and improve the simulation and correlation environments to enable data driven decisions and look for ways to boost the productivity of the entire team.

Requirements
