Thermal Engineer, Rack Level

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 We are seeking a Thermal Engineer, Rack Level to own the thermal design and validation of Etched’s L11 rack system: the liquid-cooled racks that carry our inference hardware into customer datacenters. You will take the rack from design through deployment. That means defining how it is filled, commissioned, and brought online, validating the reference CDU systems it runs on, and serving as the technical voice on facility integration for our go-to-market team and customers.

This role fits someone who has commissioned liquid cooling systems in a real datacenter and knows what goes wrong between the spec sheet and the white space. You will work closely with our tray- and module-level thermal engineers, with the mechanical, electrical, and systems teams, and with CDU and liquid-loop suppliers.
