Participate in Change Advisory Board (CAB) reviews and provide technical approval for changes impacting critical mechanical infrastructure. Establish and coordinate maintenance and safety procedures for redundant high-capacity cooling systems and backup power mechanical systems. Monitor and trend mechanical system performance through the BMS, analyze alarms, validate control sequences and setpoints, and drive infrastructure reliability initiatives. Perform root cause analysis (RCA) and drive corrective and preventive actions to closure. Support rotational on-call responsibilities and provide engineering leadership during high-severity incidents. Support Power Usage Effectiveness (PUE) optimization through airflow management, economization, and setpoint optimization. Assist with supplier selection and oversee mechanical supplier and contractor execution. Manage OEM escalations and warranty claims, and support critical spare parts strategies. Collaborate with the Operations and Design teams to develop data center mechanical designs, from project conception to issue for construction (IFC), for new builds and major infrastructure upgrades. Manage mechanical engineering programs including equipment lifecycle and obsolescence planning, cooling capacity planning, and system reliability improvements. Perform site inspections, punch walks, and operational readiness reviews to identify and resolve deficiencies before handover. Participate in Level 3-5 commissioning activities, including integrated systems testing, and validate system performance prior to production service. Ensure Day-1 operating procedures, training requirements, documentation packages, BMS readiness, and turnover deliverables are completed before facility acceptance.
