Our team responsibilities encompass design new language constructions, compiler transformation, and developer tools to the GPU on Apple’s hardware. Metal provides near-direct accesses to the GPU to give developers more control of the HW and enable developer to take advantage of Apple Silicon.\nJoin the compiler team, and you’ll collaborate with engineers across Apple to develop tools and languages to enable developers to create cutting-edge applications for graphics, compute, and machine learning using the GPU. We work closely with our partners in HW technology and GPU driver and framework team to develop feature roadmaps.qui\nThe ideal candidate should have a passion for language design, compilation techniques, GPUs, and understand how to enable developers to maximize their performance on our GPUs.\nDescription\nWe seek a results-oriented, upbeat, and focused individual passionate about learning and developing new technologies.\nThe Apple GPU Compiler Team seeks a compiler engineer to analyze, design, and build new language constructs in the front-end and middle-end optimizations to harness the power of the GPU.\nAs a key member of our team, you will apply your knowledge of compilers to investigate new architectures, design languages, and develop high-quality static and JIT front-end and middle-end optimizations for various applications from games to machine learning to image processing.\nYou will partner with a world-class team in integrating the compilers into the developer platform to maximize the performance of ML, compute, and graphics for Apple products across our platforms.\nMinimum Qualifications\nTechnical BS/MS degree or equivalent experience in Computer Science, Computer Engineering, or equivalent professional experience in compiler development.\nDeep understanding of compiler spanning semantic analysis, type systems, and optimization algorithms.\nStrong foundation of computer architecture, including memory hierarchy and instructions, and other modern processors.\nExcellent skills in software design, problem solving, debugging, and performance analysis.\nPreferred Qualifications\nUnderstand a parallel programming language for GPUs or CPUs like Metal, OpenGL, OpenCL, DirectX, or CUDA.\nFamiliarity of ML and frameworks like PyTorch\nFamiliarity with
