## About the role

You’ll drive the system-wide thermal architecture for our AI-centric consumer devices, from early concepts through detailed architecture and production validation. Balance performance, battery life, cost, and user comfort. Work hands-on across simulation, prototyping, and test to enable informed architecture analysis, proactively highlighting tradeoffs and opportunities. Collaborate closely with industrial design, mechanical, electrical, and software teams to converge holistic thermal solutions.

## What they're looking for

- 8+ years in thermal engineering with multiple shipped battery-powered consumer electronics
- Expert-level experience with thermal simulation tools (Icepak, Fluent, Ansys, or similar) and real world correlation
- Deep experience with thermal module technologies — heat pipes, vapor chambers, TIMs, graphite spreaders — and vendor evaluation at scale
- Experience in system-level power/thermal co-optimization with software or firmware teams
- Proven ability to build custom thermal test setups and drive data-backed architecture decisions during early NPI phases
- Strong cross-functional collaboration skills — translating thermal trade-offs into language that all engineering and design teams can act on
