Software Engineer - Systems ML - PyTorch

In this role, you will be a member of the PyTorch Core Systems team. The PyTorch team develops the open source software stack powering AI models and systems. The Systems team optimizes highly performant software to train and serve AI architectures. You will work closely with AI researchers to analyze deep learning models and optimize their performance within PyTorch. You will also partner with researchers to understand modern advances in AI guided software development and apply this directly towards PyTorch code and device optimization.

Examples of projects include: Rewriting core collectives to introduce fault tolerance with RDMA and GPUDirect, allowing training to continue even when nodes fail. Building a custom Python bytecode interpreter so you can capture PyTorch graphs without forcing users to rewrite their Python code. Rewriting PyTorch Distributed from scratch so you can pdb across a training job. Rewriting all of our C++ code so it’s ABI compatible for another 20 years. Fixing performance problems by changing a single register value from 1 to 0. Utilizing AI systems to optimize PyTorch compiler passesSoftware Engineer - Systems ML - PyTorch Responsibilities
