GPU Compiler Backend Engineer

What you'll do

• Design, implement, and productize backend compiler optimizations for Apple Silicon GPUs.
• Investigate and resolve complex performance and correctness issues for graphics, gaming, and machine learning workloads.
• Build compiler prototypes and run experiments to influence hardware design decisions before silicon production.
• Bring up and validate compiler support for future GPU architectures on simulators and pre-silicon platforms.
• Model and quantify the performance impact of proposed hardware features on representative workloads.
• Develop optimized GPU binaries using an LLVM-based compiler backend.
• Communicate technical trade-offs regarding hardware features to hardware and software stakeholders.

What we're looking for

• Experience with modern C++ programming.
• BS with 3+ years experience, MS, or PhD in computer science or a 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 in resolving ambiguous, open-ended technical challenges.
• Excellent written and verbal communication skills.
• Hands-on experience developing LLVM-based compiler backends (preferred).
• Experience with instruction selection, instruction schedulers, and register allocators for CPU or GPU compiler backends (preferred).
