As part of the team you will help engineer continuous improvements in stability and performance for private cloud compute, as well as help implement entirely new functionality as it emerges from the research community, in collaboration with product teams throughout Apple. We write performant and scalable frameworks (in Swift and C++) to distribute and coordinate ML inference tasks to different hardware acceleration IP blocks on different SoCs. We’re a collection of highly skilled and friendly engineers who value each other’s opinions and experience. We strive for excellence and believe strongly in the quality of our output. We have formed a team of domain experts who specializes in specific core subject areas, and also have broad experience of cloud software services and platforms. You will integrate inference code into a full service stack to ensure that user traffic is served reliably and performantly, and will have a strong focus on developing code that is easy and safe to develop, update and monitor. Experience working as a software engineer on large production systems Experience programming in: Swift, C, C++, iOS/macOS or XCode Practical experience running machine learning models and evaluating them for quality and performance metrics Familiar with Apple ML stack (ANE, CoreML, MPS/Metal), High-level general distributed ML stack (PyTorch-distributed, NCCL) and high throughput inter-chip communication systems.
