Sr. Software Development Engineer, Inference Team - AWS Neuron

About the role

AWS Neuron is the complete software stack for AWS Inferentia and Trainium, AWS purpose-built accelerators for cloud-scale machine learning. This senior software engineering role is part of the Machine Learning Inference Applications team and focuses on delivering high-performance model inference solutions for customer workloads running on Inferentia- and Trainium-powered instances. The engineer will lead the development of core serving technologies within open-source frameworks (such as vLLM and SGLang) to enable customers to serve large-scale inference efficiently on AWS Neuron. The engineer will also drive excellence in inference framework optimization and engineering best practices. The engineer will work closely with model development engineers, performance engineers, compiler engineers, and runtime engineers to ensure end-to-end model performance and deliver production-ready accuracy, scalability, and efficiency across a broad range of models and customer use cases.

Responsibilities

• Lead the customization and optimization of open-source inference frameworks (vLLM, SGLang) on AWS Neuron—including core framework logic such as scheduling and model execution.
• Apply state-of-the-art techniques in kernel development, parallel computation, distributed KV cache, speculative decoding, and systems engineering to deliver best-in-class LLM serving performance.
• Influence the team's technical roadmap by evaluating emerging inference research and translating it into production-ready features.
• Raise the bar through design leadership and mentorship.
• Collaborate closely with model development, compiler, runtime, and performance engineering teams.
