Aaron Orenstein

Software Engineer

Meta, Inc

Aaron has been at Meta for over ten years, the last two and a half on the PyTorch team, where his work focuses on the PyTorch compiler primarily the dispatcher, HOPs, and Tensor Subclasses, though he tends to roam free-range across whatever corner of the codebase needs attention. The role sits at the heart of PyTorch's execution and compiler machinery, keeping the abstractions behind both research and production workloads fast and maintainable.
