Senior Chip Architect

DESCRIPTION

AWS is the world's most comprehensive cloud platform, powering hundreds of thousands of businesses across 190 countries — from foundational services like Amazon S3 and Amazon EC2 to groundbreaking innovations like Amazon Bedrock. We build the infrastructure that powers AI at scale, including our custom silicon. Annapurna Labs, as part of AWS, is looking for talented chip architects to help develop the next generation of semiconductor platforms that will define the future of cloud computing. You will have the opportunity to work on the technologies behind the world's largest cloud provider, in a dynamic, open, and fast-paced environment.

Annapurna Labs designs custom silicon that powers AWS infrastructure. AWS Trainium delivers high-performance, cost-effective solutions for machine learning training and inference workloads. AWS Nitro provides the network cards that power ML networks, HPC networks, and general-purpose networks across AWS. AWS Graviton is a family of processors designed to deliver the best price performance for cloud workloads running in Amazon Elastic Compute Cloud (Amazon EC2).

We are looking for exceptional senior chip architects to join a world-class team that is reinventing how workloads run at scale.

As a Chip Architect, you will define architecture and micro-architecture across the complete product lifecycle — from initial requirements and early-stage technology exploration through design, implementation, and production deployment. You will explore and analyze architectural options for current and next-generation solutions, including new physical layer (PHY) and interconnect technologies, innovative protocols, and fundamental improvements to our hardware and software stack to make AWS the best place to run ML workloads and establish Annapurna Labs solutions as the industry-leading platform for Training and Inference workloads.

This role requires a top-down understanding of our complete solution stack, including system architecture, software stack, chip architecture, and microarchitecture. You will work in close collaboration with multiple groups — Software, Silicon engineering, System and Platform teams, and cross-functional teams across AWS. Your architectural decisions will influence the design of chips deployed on millions of servers worldwide, powering the future of AI, machine learning, and general-purpose compute. This is an opportunity to have large-scale impact on how the world builds and deploys infrastructure.
