Detailed Description

Performs tasks such as, but not limited to, the following:

  • Lead thermal evaluations for new products, design decisions, and risk mitigation.
  • Guide thermal management in DFx, PCB layout, and heat dissipation design (compliance with ASHRAE, NEBS).
  • Collaborate with cross-functional teams (design, manufacturing, quality, reliability) to solve thermal issues.
  • Drive root cause analysis with CFD simulations; manage failure analysis at manufacturing sites.
  • Lead verification plans for certification programs; review reliability test results.
  • Develop thermal testing standards; guide team in using thermal testing tools (thermocouples, IR cameras, wind tunnels).
  • Support thermal certification of second-source components; review heat dissipation compatibility.
  • Participate in factory readiness and production line thermal setup.
  • Coordinate cross-project resources (equipment, manpower) to avoid conflicts.
  • Conduct training, build knowledge base, and share best practices on thermal debugging.
  • Research next-gen cooling technologies (liquid cooling, AI workload thermal management) and evaluate feasibility.

Knowledge/Skills/Competencies

  • Proficiency in heat transfer principles (conduction, convection, radiation) and fluid dynamics.
  • Skilled in using CFD tools such as ANSYS Icepak and FloTHERM, as well as CAD software such as SolidWorks.
  • In-depth understanding of data center cooling technologies (air cooling/liquid cooling solutions), thermal impact of server PCBs, and heat dissipation challenges of AI/HPC hardware. Ability to interpret and revise industry standards.
  • Strong leadership, strategic thinking, cross-team communication, and knowledge transfer skills.

Physical Demands

  • Duties of this position are performed in a normal office environment.
