Senior Thermal Engineer in Fremont

Job Description

Join a fast-growing global thermal management company building next
- liquid cooling solutions for AI/HPC & hyperscale data centers
. You will lead thermal design, simulation, and hands‑on validation—turning advanced concepts into production‑ready systems deployed in real data center environments.

• Design and develop liquid cooling architectures for AI and high‑power‑density servers.
• Lead CFD thermal‑fluid 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
  .
• Proven experience developing liquid cooling systems for electronics/servers/data centers.
• 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).
• Location:
  
  47730 Westinghouse Dr Fremont, CA 94539

Build real products that power next- data center infrastructure—your work will go from concept → lab validation → real‑world deployment.
