Data Center Thermal Engineer - Liquid-Cooling Specialist

Supermicro; Wayne (CA); On-site; USD 133,000 - 150,000; Full time

Job summary

Supermicro is seeking a Data Center Thermal Engineer to design, validate, and maintain advanced liquid cooling systems across AI labs and data centers. You will assist with CDU monitoring, high-density GPU cooling, and testing, collaborating with hardware, controls, and facility teams.

The role requires 5+ years in thermal management, fluid systems, and data center infrastructure, with hands-on talent in instrumentation and diagnostics. Strong communication and problem-solving are essential.

Qualifications

• BS degree in Mechanical/Thermal engineering or related field.
• 5+ years hands-on experience in thermal management, liquid cooling, or data center infra.
• Hands-on experience with mechanical systems, lab equipment, thermal/fluid testing, or data center cooling infra.
• Foundational understanding of Direct-to-Chip liquid cooling, heat exchangers, heat transfer, and fluid mechanics.
• Knowledge of fluid dynamics, thermodynamics, hydraulic networks, and pressure/flow relationships.
• Familiarity with CDU operation, pumps, valves, manifolds, piping, and liquid cooling architectures.
• Understanding of thermal resistance, heat transfer, flow balancing, and pressure drop.
• Basic knowledge of coolant chemistry and materials compatibility.
• Experience with temperature, pressure, flow measurements and lab instrumentation.
• Ability to interpret system data and perform diagnostic troubleshooting and root-cause analysis.
• Familiarity with BMS/PLC systems and telemetry is a plus.
• Strong technical communication skills and documentation experience.
• Hands-on, analytical, continuous-learning mindset for lab, data center, and field environments.

Responsibilities

• Assist with specification, evaluation, installation and assembly of high-density liquid cooling systems.
• Troubleshoot hydraulic, thermal, and mechanical issues and perform root-cause analysis.
• Support site commissioning, energization, functional verification, and performance testing of large-scale cooling installations.
• Develop and maintain runbooks, procedures and troubleshooting docs for liquid cooling infra.
• Assist with monitoring fluid chemistry, material compatibility, pressure-drop budgets and flow requirements.
• Set up, validate, and monitor sensors and instrumentation and support control-logic for data collection and telemetry.
• Lead or coordinate FMEA reviews and support rapid-response containment for leaks or anomalies.
• Collaborate with senior engineers and deployment teams during system development and site expansions.
• Inspect and assist with qualification/testing of vendor components like QDCs, heat exchangers, valves, pumps, piping and fluids.
• Support system validation by collecting/analyzing flow, pressure, temperature data against design requirements.
• Contribute to continuous improvement for reliability, maintainability, and safety.
