Thermal Engineer

About the role We're growing the thermal team, so you'll have real scope and a say in how the function is built.   You will own the thermal design that enables our AI accelerators — from the silicon package out to the system-level. You'll take thermal solutions from concept through production: building the models, running the simulations, designing the solution, and then proving it on real hardware. This is a  hands-on role  with a heavy validation component — you'll spend as much time closing the gap between your model and your measurements as building the model in the first place. You'll work directly with vendors on thermal solution development, and with our packaging, mechanical, and electrical teams on the tradeoffs that decide how much power we can put through a part.    What You'll Do Own package-level thermal design and the thermal solution that supports it, from concept through production.   Own thermal validation and verification — build the test plans, run them, and close the loop between measurement and model.   Drive hands-on thermal simulation s in Ansys  Icepak  (or equivalent) and  1D flow network modeling   ( Macroflow  or  equivalent) for  system - level  analysis.   Support  system-level thermal  design  for datacenter  applications and  engage directly with vendors on thermal solution development.   Use and develop AI - assisted tool flows to accelerate thermal modeling, data processing, and signoff timelines.   What We're Looking For 5+ years of thermal  design  experience on  advanced  compute  hardware , with  demonstrated  ownership of a thermal design from concept through production   Exceptional abilities in thermal design and analysis:  strong background in  heat transfer and fluid dynamics fundamentals    Hands-on with Ansys  Icepak  (or equivalent)  for detailed CFD,  and with 1D flow network tools ( Macroflow   or equivalent) for system-level analysis   Demonstrated ability to work closely with packaging, mechanical, electrical, and vendor partners to converge and  validate  thermal solutions   Experience in designing liquid cooled solutions for data center applications   Experience with  TIM selection and characterization   Ability to distill complex thermal data into actionable recommendations for both technical and non-technical stakeholders   Hands-on thermal measurement and characterization experience -- thermal test development, instrumentation, and test-to-model correlation. Experience  establishing  thermal test capability from the ground up is a plus     Compensation Final offers depend on level, location, and skills relevant to the role.
