Senior backend GPU Compiler Engineer

Role

You will be part of a diverse and distributed team of engineers who maintain and develop our GPU compiler software, supporting a range of graphics and compute APIs while targeting multiple GPU generations with varying ISAs. The GPU compiler is a central part of the drivers that we develop for these APIs. As such, they are critical to achieving optimal runtime performance of graphics/compute workloads on our GPUs, through the production of optimal hardware code with minimal compilation time.

• Maintain and develop our GPU compilers, with a focus on the LLVM based middle-end
• Diagnose and resolve incorrect compilation from customer issues, QA or conformance testing
• Analyse code‑quality/runtime performance and implement optimisations
• Add support for new/future GPU functionality to the compilers
• Add support for new/future API/input language features
• Identify/suggest changes to improve output quality or compilation time
• Provide technical insight and collaborate with others to constantly improve our GPU compilers

Committed to making your customers, stakeholders and colleagues successful, you’re an excellent communicator, listener and collaborator who builds trusted partnerships by delivering what you say when you say. You’re curious, solutions oriented and a world‑class problem solver who constantly seeks opportunities to innovate and achieve the best possible outcome to the highest imaginable standard.

• Advanced C++ programming skills
• Strong knowledge of processes and techniques for compiler backend code‑generation
• Experience with production‑quality compiler development
• Strong compiler theory, especially optimisation
• Ability to analyse generated code down to the ISA level
• Computer architecture knowledge

• Knowledge and experience with graphics/compute APIs such as OpenCL, CUDA, Vulkan, OpenGL or DirectX
• Experience with compilation specifically for GPUs
• LLVM backend development
• An appreciation of multi‑threaded and/or parallel computation and associated complexity
• Knowledge of GPGPU programming
• Knowledge of AI/ML workloads that are amenable to GPU execution
