Product Design Engineer, Thermals
Hybrid (San Jose)full-timePosted 6mo ago
About the role
You’ll drive the system-wide thermal architecture for AI-centric consumer devices, from concept to production validation, balancing performance, battery life, cost, and user comfort while collaborating across industrial, mechanical, electrical, and software teams.
Responsibilities
- Define and own the thermal architecture from early architecture & NPI through production, including foundational system architecture simulation & analysis, material selection, thermal solution design, and cost optimization.
- Translate product use cases and real-world usage profiles into thermal loading scenarios that drive early design iteration
- Conduct detailed thermal analysis at variable fidelity levels as needed - analytic analysis for team directional analysis, coarse analysis for quick iteration of parallel ideas, and detailed analysis for high fidelity studies.
- Design and build custom thermal test infrastructure and measurement methodologies tailored to each product program
- Partner cross-functionally to ensure thermal constraints are integrated into system-level decisions around power budgets, enclosure design, and silicon selection
Qualifications
- 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
