Senior Thermal Engineer

Job Description

1.Role Summary：

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.

2.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.

3.What We’re Looking For (Required)：

  • 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.

Nice to Have：

  • 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).

4.Work Style:

  • Bay Area on-site role (lab-focused).
  • Location:47730 Westinghouse Dr Fremont, CA 94539

5.Why Envicool?

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