Sr. Mechanical Engineer, Annapurna Labs, Artificial Intelligence Hardware
Amazon · Austin, TX · Posted 94 days ago
Own end-to-end thermal and mechanical architecture for Trainium and Inferentia accelerator platforms, from chip package through liquid-cooled rack infrastructure at AWS scale.
Annapurna Labs (our organization within AWS) designs silicon and software that accelerates innovation. Customers choose us to create cloud solutions that solve challenges that were unimaginable a short time ago—even yesterday. Our custom chips, accelerators, and software stacks enable us to take on technical challenges that have never been seen before, and deliver results that help our customers change the world.
As a member of the Annapurna ML/AI Mechanical Thermal Engineering team, you'll own the end-to-end thermal and mechanical architecture for ML/AI accelerator platforms — from initial concept through production deployment and ongoing fleet operations. You'll design mechanical and cooling solutions for some of the highest power-density silicon in the industry, balancing performance, reliability, cost, and operational efficiency at massive scale.
This is a technically challenging role requiring you to operate in ambiguity and at a fast pace. You'll collaborate across silicon design, electrical engineering, firmware, manufacturing, supply chain, and operations teams to deliver platforms that power AWS ML/AI services at global scale.
Key job responsibilities As a Cloud Hardware Development Engineer (Thermal/Mechanical), you will:
Own the complete thermal and mechanical design for ML/AI accelerator platforms — from rack-level infrastructure down to chip packaging, including mechanical packaging, structural integrity, and interconnect systems
Define thermal and mechanical design requirements, establish design targets, and drive cross-functional alignment that enables parallel development across hardware, firmware, and software teams
Deliver production platforms through the full lifecycle: concept, design, analysis, prototyping, validation, manufacturing ramp, and fleet operations
Thermal & Mechanical Design
Design and optimize cooling solutions (air and liquid) for high-power-density ML/AI accelerators
