About the Role
You will lead thermal strategy for next-generation AI platforms, architecting and validating cooling solutions for dense PCIe cards, multi-chip servers and rack-level environments. You will lead CFD simulation, define validation and reliability strategies, work with suppliers and manufacturing, and drive design reviews while mentoring engineers. Some international travel is expected.
Requirements
- Bachelor's or master's degree in Thermal Engineering, Mechanical Engineering or related field
- 10+ years of thermal design and architecture experience in enterprise servers, HPC or specialized AI hardware
- Experience designing and deploying server-to-rack liquid-cooling systems (CDUs, manifolds, pumps, chillers, heat exchangers, cold plates, quick disconnects)
- Proficiency in Ansys IcePak, FloTHERM or SOLIDWORKS Flow Simulation and 3D CAD, preferably SolidWorks
- Expertise in airflow management and hybrid cooling, and lab validation
- Familiarity with Longwin thermal testing equipment, data loggers, pressure-decay analyzers, flow meters
- Ability to travel internationally up to 10%
- Eligibility to access U.S. export-controlled technology
Responsibilities
- Architect and validate thermal solutions for dense PCIe cards, multi-chip servers and rack-level environments
- Define approaches for integrating liquid cooling with air-cooled and hybrid thermal paths
- Lead CFD simulation at chip, system and rack levels
- Guide design of cold plates, manifolds, TIMs, vapor chambers, heat pipes, pumps and fans
- Define and oversee validation and reliability strategies including thermal cycling, leak detection, pressure-decay and flow testing
- Lead supplier and manufacturing engagements, review designs and tooling, and support critical builds and manufacturing qualification
- Drive thermal design reviews and engineering best practices, and mentor engineers
- Manage thermal component integration and lifecycle data in PLM and produce specifications, test reports and design guidelines
