Thermal Engineer

We'regrowing the thermal team,soyou'llhave real scope and a say in how the function is built.

You will own the thermal design thatenablesour AI accelerators from the silicon package out to thesystem-level.You'lltake thermal solutions from concept through production: building the models, running the simulations, designing the solution, and then proving it on real hardware. This is ahands-on rolewith a heavy validationcomponentyou'llspend as much time closing the gap between your model and your measurements asbuildingthe model in the first place.You'llwork directly with vendors on thermal solution development, and with our packaging, mechanical, and electrical teams on the tradeoffs that decide how much power we canputthrough a part.

• 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 simulations in AnsysIcepak(or equivalent) and1D flow network modeling(Macrofloworequivalent) forsystem-levelanalysis.

• Supportsystem-level thermaldesignfor datacenterapplications andengage directly with vendors on thermal solution development.

• Use and develop AI-assisted tool flows to accelerate thermal modeling, data processing, and signoff timelines.

• 5+ years of thermaldesignexperience onadvancedcomputehardware, withdemonstratedownership of a thermal design from concept through production

• Exceptional abilities in thermal design and analysis:strong background inheat transfer and fluid dynamics fundamentals

• Hands-on with AnsysIcepak(or equivalent)for detailed CFD,and with 1D flow network tools (Macroflowor equivalent) for system-level analysis

• Demonstrated ability to work closely with packaging, mechanical, electrical, and vendor partners to converge andvalidatethermal solutions

• Experience in designing liquid cooled solutions for data center applications

• Experience withTIM 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. Experienceestablishingthermal test capability from the ground up is a plus
