Head of Platform Mechanical & Thermal Engineering

About Etched Etched is building hardware for frontier intelligence. We co-design chips, racks, software, and manufacturing to deliver best-in-class throughput and latency across both prefill and decode workloads. Our first products are heavily focused on inference. Backed by hundreds of millions from top-tier investors and staffed by leading engineers, Etched is redefining the infrastructure layer for the fastest growing industry in history. Job Summary Our Platform Team designs the servers and systems that deliver our chips’ full potential. We are seeking a Head of Platform Mechanical & Thermal Engineering to lead all aspects of mechanical architecture, advanced cooling, and CAD infrastructure for next-generation high-power density ASIC systems. This leader will build and scale the mechanical and thermal engineering organization, with a strong focus on liquid cooling technologies and rack-level thermal management. Siemens NX is our standard 3D CAD platform, and you will also drive the deployment of industry-leading CFD and rack simulation tools to ensure performance, manufacturability, and reliability at datacenter scale. Key Responsibilities - Leadership & Team Growth - Build, mentor, and scale a team of mechanical and thermal engineers. - Define hiring plans and technical standards for advanced cooling and mechanical design. - Foster a culture of engineering rigor and cross-disciplinary collaboration. - Mechanical & Thermal Architecture - Own the design of server enclosures, modules, and racks optimized for high-power ASICs. - Drive liquid cooling solutions (cold plates, manifolds, quick-disconnects, CDU integration) as well as air-assisted hybrid cooling where applicable. - Ensure mechanical designs meet standards for manufacturability, serviceability, and reliability under extreme thermal loads. - Tools & Infrastructure - Deploy and optimize Siemens NX for CAD/PLM workflows, with integrated libraries and release processes. - Establish and scale simulation infra
