Senior Thermal Engineer

What You’ll Do

• Design and develop liquid cooling architectures for AI and high-power-density servers.
• Lead CFD thermal-fluid simulation/modeling to optimize flow distribution, pressure drop, and heat transfer.
• Plan and execute lab + rack-level + field thermal performance testing (reliability, leak detection, long-term validation).
• Collaborate with customers/data center operators/suppliers to define requirements and ensure successful integration.
• Evaluate coolant chemistry, material compatibility, and corrosion control strategies.
• Lead FMEA / risk analysis for thermal systems and key components.
• Explore new technologies and sustainability metrics (
  PUE/WUE
  ) to support roadmap and global deployments.
• PhD in Thermal/Mechanical Engineering (or closely related field).
• Strong expertise in heat transfer, fluid dynamics, thermal system design
  .
• Hands-on proficiency with CFD tools (ANSYS Fluent/Icepak/Star-CCM+ or equivalent).
• Hands-on lab experience with thermal testing, instrumentation, and validation.
• Strong technical communication skills; comfortable working cross-functionally and customer-facing.
• Production experience with liquid cooling deployments.
• Familiarity with AI/GPU platforms, high-density racks, hyperscale infrastructure.
• Knowledge of OCP standards /
  ASHRAE liquid cooling guidelines / compliance requirements.
• Experience with sustainability-driven thermal optimization (PUE/WUE, energy efficiency).

• Bay Area on-site role (lab-focused).
