Job Summary
Responsible for maintaining the reliable operation and performance of AI data center cooling infrastructure, with a specific focus on Coolant Distribution Units (CDUs) and secondary cooling loops. The role supports critical cooling operations in a high-density AI/GPU data center environment.
The L2 HVAC scope is limited to CDUs and secondary cooling loops. BDx engineers handle pumps, heat exchangers, manifolds, and facility cooling systems.
Key Responsibilities
Operate, monitor, and maintain CDUs and secondary cooling loops within the AI data center environment.
Troubleshoot cooling-system issues involving temperature, flow, pressure, differential pressure (DP), valves, water quality, and leak detection.
Interpret P&IDs, engineering drawings, and system documentation to support maintenance and troubleshooting.
Monitor cooling performance and respond to alarms, abnormalities, and operational incidents.
Perform preventive maintenance and support corrective maintenance activities.
Follow established SOPs, MOPs, and EOPs when executing operational tasks and system changes.
Support incident management, change management, root cause analysis (RCA), and continuous improvement.
Provide 24×7 shift or on-call support as required.

3–5 years of hands-on experience in mission-critical HVAC or cooling systems, preferably in data centers or other 24×7 critical environments.
Practical exposure to liquid cooling systems, CDUs, and secondary cooling loops.
Experience troubleshooting cooling-system performance, leaks, and water-quality issues.
Nice-to-Have Experience
Experience supporting high-density AI/GPU data center cooling environments.
OEM training or certification in CDU or liquid-cooling systems. Training may also be provided after employment.
Required Skills
CDU & Secondary Cooling Loop Operations: Hands-on knowledge of CDU operations, liquid cooling, secondary cooling loops, and related HVAC components.
Technical Troubleshooting & Diagnostics: Ability to read P&IDs and drawings and troubleshoot temperature, flow, pressure, DP, pump, valve, water-quality, and leak-detection issues.
Critical Facilities Operations: Knowledge of N+1/2N redundancy, SOP/MOP/EOP procedures, preventive maintenance, incident and change management, and RCA.
Preferred Skills
Chiller and cooling tower/dry cooler systems
CRAH/AHU systems and BMS controls
Pumps, heat exchangers, valves, and piping systems
Liquid cooling and data center cooling technologies
CDU OEM systems and technical documentation
Critical environment operations and maintenance
