Amazon Senior Software Development Engineer, AWS Neuron Inference in Cupertino, California


AWS Neuron is the complete software stack for the AWS Inferentia and Trainium cloud-scale machine

learning accelerators and the Trn1 and Inf2 servers that use them. This role is for a software engineer in the Neuron Inference (ML Apps) team for AWS Neuron.

This role is responsible for development, enablement and performance optimization (latency, throughput) of a wide variety of ML model families, including massive scale large language models like Llama3, DBRX, and beyond, as well as Stable Diffusion, Vision Transformers and many more.

The Neuron Inference team works side by side with compiler engineers and runtime engineers to create, build and tune distributed inference solutions with Trn1/Inf2. Experience optimizing inference performance for both latency and throughput on these large models using PyTorch or JAX is a must. Experience with technologies/tools such as vLLM, Hugging Face, multi-modal inference, etc. is highly valued.

Key job responsibilities

This role will help lead the efforts building distributed inference support into Pytorch, Tensorflow using XLA and the Neuron compiler and runtime stacks. This role will help tune these models to ensure highest performance and maximize the efficiency of them running on the AWS Trainium and Inferentia silicon. Strong software development using C++/Python and ML knowledge are both critical to this role.
