ML Framework (MetalLM) Engineer

Apple's ML Frameworks team in GPU, Graphics and Displays org 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. The team provides GPU acceleration for popular Machine learning libraries such as TensorFlow, PyTorch and JAX using Metal runtime and device backend. They optimize compute performance with kernels and computational graphs that are fine-tuned for the unique characteristics of each Metal GPU family.

Responsibilities include:

• Designing and developing compiler-based optimizations for Metal backend in ML frameworks such as torch.compile for PyTorch
• Working on cutting-edge ML inference framework projects and optimizing code for efficient and scalable ML inference using distributed techniques
• Implementing features of Metal device backend for ML training acceleration technologies
• Working with Core teams of PyTorch, JAX or Tensorflow to provide Metal runtime and device backend support
• Tuning GPU-accelerated training across products
• Performing in-depth analysis, compiler and kernel level optimizations to ensure the best possible performance across hardware families

The role offers the opportunity to influence the design of compute and programming models in next-generation GPU architectures. The team is always looking for exceptionally dedicated individuals to grow their outstanding team.

Required Qualifications:

• 3+ years of programming and problem-solving experience with C/C++/ObjC
• Experience with Distributed training or inference techniques
• Knowledge of GPU compute programming models & optimization techniques
• Experience with system-level programming and computer architecture

Preferred Qualifications:

• Contributions to an AI framework such as PyTorch, JAX or Tensorflow
• Experience with graph compilers such as Triton, OpenXLA or LLVM/MLIR
• Good understanding of machine learning fundamentals
