Thermal Performance Engineer

1.Role Summary： Join a fast-growing global thermal management company building next-generation 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).
