GPU Software Architecture Engineer, Graphics, Games, & ML

Apple Silicon GPU SW architecture team within the Media, Graphics & Compute Technologies group is seeking a senior/principal engineer to lead server-side ML acceleration and multi-node distribution initiatives. You will help define and shape our future GPU compute infrastructure on Private Cloud Compute that enables Apple Intelligence.

In this role, you'll be at the forefront of architecting and building our next-generation distributed ML infrastructure, where you'll tackle the complex challenge of orchestrating massive network models across server clusters to power Apple Intelligence at unprecedented scale. It will involve designing sophisticated parallelization strategies that split models across many GPUs, optimizing every layer of the stack-from low-level memory access patterns to high-level distributed algorithms-to achieve maximum hardware utilization while minimizing latency for real-time user experiences. You'll work at the intersection of cutting-edge ML systems and hardware acceleration, collaborating directly with silicon architects to influence future GPU designs based on your deep understanding of inference workload characteristics, while simultaneously building the production systems that will serve billions of requests daily.\n\nThis is a hands-on technical leadership position where you'll not only architect these systems but also dive deep into performance profiling, implement novel optimization techniques, and solve unprecedented scaling challenges as you help define the future of AI experiences delivered through Apple's secure cloud infrastructure.

10+ years of experience in GPU programming (CUDA, ROCm) and high-performance computing, successfully optimizing large-scale parallel workloads.\n\nStrong experience with inter-node communication technologies (InfiniBand, RDMA, NCCL) in the context of ML training/inference\n\nMust have excellent system programming skills in C/C++\n\nDeep understanding of distributed systems and parallel computing architectures\n\nUnderstand how tensor frameworks (PyTorch, JAX, TensorFlow) are used in distributed training/inference\n\nBachelor's degree in Computer Science, Engineering, Mathematics, or a related technical field

Familiar with model development lifecycle from trained model to large scale production inference deployment\n\nProven track record in ML infrastructure at scale\n\nPython is a plus\n\nPhD in Computer Science, Engineering, Mathematics, or a related technical field
