About the role

What will you do at Apple?

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.
DESCRIPTION
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
customers. We 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.
MINIMUM QUALIFICATIONS
Experience with modern C++ programming BS with 5+ years experience, MS, or PhD
in computer science or related field Strong background in compiler backend
technologies (LLVM preferred) Knowledge of GPU architectures and how they differ
from CPU architectures Demonstrated autonomy and ownership resolving ambiguous,
open-ended technical challenges Excellent written and verbal communication
skills
PREFERRED QUALIFICATIONS
Hands-on experience developing LLVM-based compiler backends Experience with
instruction selection, instruction schedulers, and register allocators for CPU
or GPU compiler backends Experience driving production compiler issues to
resolution in a fast-paced environment
