HVAC Engineer - Data Center

About the role

Responsible for the reliable operation and performance of AI data center cooling infrastructure, with primary focus on Coolant Distribution Units (CDUs) and secondary cooling loops.

Key responsibilities

• Monitor and troubleshoot temperature, flow, pressure, differential pressure, coolant quality, dew-point margin, and leak-detection alarms
• Perform preventive and corrective maintenance for CDU and secondary cooling loop systems
• Analyze system trends and operational data to identify performance degradation and potential cooling issues
• Manage cooling redundancy, failover procedures, and recovery during cooling incidents
• Work closely with other engineers covering pumps, heat exchangers, manifolds, and facility cooling systems
• Coordinate with L1 technicians, IT teams, OEM specialists, and other engineering teams during cooling incidents
• Support incident management, root-cause analysis, and continuous improvement of cooling system reliability
• Follow applicable SOP, MOP, EOP, safety, maintenance, and operational procedures
• Provide 24×7 shift to support and respond to critical cooling incidents when required

About you

• Diploma or Bachelor's Degree in Mechanical Engineering, Building Services Engineering, HVAC Engineering, Facilities Engineering, or equivalent technical qualification
• Minimum 3–5 years of hands-on experience operating and maintaining mission-critical HVAC/cooling systems, preferably in data centers or other 24×7 critical environments
• Experience with liquid cooling systems, CDUs, secondary cooling loops, or high-density data center cooling is highly desirable
• Working knowledge of pumps, valves, piping, heat exchangers, and associated cooling controls
• Ability to interpret P&IDs, mechanical drawings, equipment schematics, and monitoring/BMS alarms and trends
• Experience troubleshooting temperature, flow, pressure, differential pressure, coolant quality, dew-point, and leak-detection issues
• Understanding of cooling-system redundancy, including N+1 and 2N, maintenance, and failover procedures
• Familiarity with SOP, MOP, EOP, preventive maintenance, change management, incident management, and RCA
• English is a must, both written and spoken
• Willing and able to provide 24×7 shift to support and respond to critical facility incidents
