Lead Thermal Systems Engineer

We are seeking a highly skilled Thermal Systems Engineer to lead the design, analysis, and validation of advanced cooling systems for high-density data center environments. This role focuses on ensuring system reliability, thermal performance, and compliance with industry standards through rigorous testing and certification processes.

What You Will Do

• Design and optimize thermal systems for high-power-density environments, ensuring robust heat transfer and fluid flow performance.

• Conduct detailed thermal simulations and CFD modeling to validate system behavior under varying operational conditions.

• Develop and execute comprehensive test plans including hydrostatic pressure testing, thermal cycling, vibration, and shock testing in accordance with standards such as ASME, IEC, and ASTM.

• Collaborate with cross-functional teams to ensure mechanical integrity, material compatibility, and corrosion resistance of wetted components.

• Analyze field data and lab results to drive continuous improvement in system reliability and efficiency.

• Support regulatory compliance efforts including safety, EMC, and environmental certifications (e.g., UL, CE, RoHS, REACH).

• Author technical documentation including test protocols, certification reports, and installation guidelines.

• Interface with external testing labs and internal stakeholders to coordinate validation activities and ensure timely delivery of certified systems.

Minimum Qualifications
