This role is focused on developing and validating architectural models for advanced graphics processing units (GPUs) within Apple's Silicon Technologies group. The team is responsible for ensuring that Apple products can efficiently handle complex tasks through innovative hardware solutions. Engineers will work on pre-silicon functional and performance modeling, contributing to the design of low power GPUs. Collaboration across functional teams is essential to drive best practices in hardware and software solutions.
