Data Center Thermal Engineer: High-Density Liquid Cooling

Support Revolution; San Jose (CA); On-site; USD 133,000 - 150,000; Full time

Job summary

Supermicro is seeking a Data Center Thermal Engineer to support the design, validation, and operation of high-density liquid cooling across AI labs and data centers. You will assist with fluid system integration, CDU monitoring, heat rejection loop testing, and cooling-tower oversight.

This role requires hands-on hardware work in lab and field settings. You will collaborate with senior engineers on system development, testing, and troubleshooting, and contribute to reliability and performance

Qualifications

• B.S. degree in Mechanical Engineering, Thermal Engineering, Chemical Engineering, or a related engineering field.
• 5+ years of hands-on experience in thermal management, liquid cooling, fluid systems, mechanical design, data center infrastructure, or a related field.
• Hands-on experience with mechanical systems, laboratory equipment, thermal/fluid testing, or data center cooling infrastructure.
• Foundational understanding of Direct-to-Chip (D2C) liquid cooling, heat exchangers, heat transfer, and fluid mechanics.
• Familiarity with Coolant Distribution Unit (CDU) operation, pumps, control valves, manifolds, piping systems, and liquid cooling architectures.
• Understanding thermal resistance, heat transfer, flow balancing, and pressure drop concepts.
• Basic knowledge of coolant chemistry and materials compatibility.

Responsibilities

• Assist with the specification, evaluation, installation, and physical assembly of high-density liquid cooling systems, including CDUs, manifolds, and piping.
• Troubleshoot hydraulic, thermal, and mechanical issues and support root-cause analysis.
• Support site commissioning, system energization, functional verification, and performance testing of large-scale liquid cooling installations.
• Develop and maintain runbooks, procedures, and troubleshooting documentation.
• Assist with monitoring and managing fluid chemistry, pressure budgets, and system redundancy.
• Set up, validate, and monitor sensors and instrumentation for data collection and telemetry.
• Lead or coordinate FMEA reviews and assist in containment after leaks or thermal excursions.
• Collaborate with engineers during system development and site expansions.
• Inspect and qualify vendor components like QDCs, heat exchangers, valves, and pumps.
• Analyze flow, temperature, and pressure data to verify performance against design.
