Apple GPU Compiler Backend Engineer

In this role you will design implement and productize advanced backend compiler optimizations for Apple Silicon GPUs working across the full lifecycle from prototyping through production shipping. You will collaborate cross-functionally with hardware and software teams to resolve complex compiler and performance challenges driving optimizations to completion. The GPU compiler backend you help build ships in every Apple device with a GPU directly impacting graphics gaming and machine learning workloads across the entire product line.

Our GPU Compiler Backend team is responsible for the design implementation and productization of the compiler that generates optimized code for Apple Silicon GPUs. We build synergies with hardware and software teams from early architecture exploration through production hardening and shipping and serve as the last line of defense for performance and correctness before code reaches are seeking a skilled Compiler Backend Engineer to join our team. This role spans driving compiler optimization projects to completion resolving complex ambiguous production issues escalated by key partners (ProApps Machine Learning and Gaming) and contributing to the exploration of new GPU architecture features. You will work on an LLVM-based compiler backend that generates optimized GPU binaries for graphics and compute workloads across every Apple device with a GPU.
