GPU Compiler Backend Engineer

What you'll do

• Design, implement, and productize backend compiler optimizations for Apple Silicon GPUs.
• Resolve complex performance and correctness issues escalated by graphics, gaming, and machine learning partners.
• Partner with architects to co-design instruction sets and micro-architecture features based on compiler prototypes.
• Validate compiler support for future GPU architectures using simulators and pre-silicon platforms.
• Model and quantify the performance impact of proposed hardware features on representative workloads.
• Develop an LLVM-based compiler backend that generates optimized binaries for graphics and compute tasks.
• Communicate technical trade-offs regarding hardware features to both 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 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).
