## Description

Apple's ML Frameworks (MetalLM) team in GPU, Graphics and Machine Learning works on enabling Apple Intelligence through high-performance, distributed inference of GenAI applications (such as LLMs) on Private Cloud Compute. You will get to work on custom-built server hardware that brings the power and security of Apple silicon to the data center.

Team also works on GPU acceleration of ML Training frameworks such as PyTorch and JAX using Metal runtime and device backend. We are looking for engineers with systems background who are deeply passionate about building scalable, efficient, and production-grade solutions tailored for high-throughput GPU execution., Our team is seeking extraordinary machine learning and GPU programming engineers who are passionate about providing robust compute solutions for accelerating Machine learning libraries on Apple Silicon. Role has the opportunity to influence the design of compute and programming models in next generation GPU architectures. * Responsibilities: Work on cutting-edge ML inference framework project and optimize code for efficient and scalable ML inference using distributed compute strategies such as data, tensor, pipeline and expert parallelism. Develop kernel and compiler level optimizations and perform in-depth analysis to ensure the best possible performance across Server hardware families. Apply advanced model optimization techniques including speculation, quantization, compression, and others to maximize throughput and minimize latency. Collaborate closely with hardware, compiler, and systems teams to align software performance with hardware capabilities. Analyze and improve performance
metrics such as end-to-end latency, TTFT, TBOT, memory footprint, and compute efficiency. Implement features of Metal device backend for ML training acceleration technologies If this sounds of interest, we would love to hear from you!
