About the role

We are looking for an experienced Thermal Engineer to own the cooling design of our server solutions, from concept through validation. You will develop air and liquid cooling architectures, model them with CFD, and prove them out in the lab by correlating test data against simulation.

This is a hands-on, cross-functional role. You will work closely with electrical, mechanical, and package engineers to balance thermal performance against power, layout, mechanical, and you will bring a working knowledge of data center architecture and the cooling ecosystem offered by suppliers.
