Key job responsibilities
You will lead the effort to build distributed training and post-training support into PyTorch and JAX for Trainium accelerators. You will work across PyTorch and Neuron software stack with the Neuron compiler and runtime teams to enable and fine tune large-scale training, post training, and reinforcement learning workloads on the latest Trainium instances. You will own the parallelism strategies these models depend on, spanning data, tensor, pipeline, expert, and context parallelism, and apply reduced-precision formats where they measurably pay off. You will profile end to end to determine whether a workload is bound by compute, memory, collectives, or host overhead, then drive the fix to the layer that owns it, working with compiler, runtime, and collectives engineers to land it. You will translate the performance gaps you characterize into requirements that influence frameworks, and contribute upstream to the open source frameworks our customers train on.
