Responsibilities
Define and drive thermal architectures for rack-mounted systems, compute modules, and advanced packages, including air- and liquid-cooled solutions. Establish thermal requirements, budgets, and margins to meet system performance and reliability goals
Develop and execute steady-state and transient thermal simulations at die, package, module, and system levels. Use simulation results to guide design tradeoffs, cooling technology selection, and system integration decisions
Design and evaluate thermal solutions including heat sinks, heat spreaders, cold plates, manifolds, TIMs, and system airflow. Support innovation in liquid cooling approaches for high-power, high-density electronics
Define thermal test strategies and instrumentation plans. Execute thermal characterization, power mapping, and correlation of lab data with simulation results. Drive design iterations based on test outcomes
Partner closely with mechanical, electrical, packaging, and manufacturing engineers to ensure thermal considerations are integrated into system, enclosure, and package designs. Collaborate with external partners (ODMs, OSATs, cooling vendors) as needed
Apply thermal DFM principles early in the design cycle. Participate in FMEA activities, identify thermal risks, and lead mitigation strategies to address reliability, yield, and manufacturability challenges
Develop comprehensive thermal documentation, including requirements, specifications, simulation reports, test plans, and validation summaries. Present findings and recommendations to technical and non-technical stakeholders
Support qualification and reliability testing efforts, including thermal cycling and stress testing, and ensure compliance with relevant industry standards
Qualification
Required
Bachelor's or Master's degree in Mechanical Engineering, Thermal Engineering, or a related field
5+ years of experience in thermal engineering for electronics, with a proven track record of bringing products from concept to high-volume production
Strong knowledge of heat transfer and thermal management for electronics systems, including package- and system-level cooling
Experience with thermal simulation tools such as Icepak, Flotherm, COMSOL, or ANSYS
Familiarity with thermal validation, lab instrumentation, and data analysis
Strong written and verbal communication skills, with the ability to clearly document technical concepts and collaborate across cross-functional teams
Preferred
10+ years of experience in thermal design for high-performance computing, AI, or communication hardware
Experience with advanced packaging and high-power-density modules (e.g., multi-die, chiplet-based systems)
Experience designing and deploying liquid cooling solutions, including cold plates, manifolds, and CDUs
Understanding of thermo-mechanical interactions such as warpage, CTE mismatch, and TIM behavior
Experience collaborating with ODMs, OSATs, and manufacturing partners to solve thermal and integration challenges
Experience with statistical or data analysis tools such as JMP is a plus
