Facilities Operations Technician III – Mechanical (OP4)

About the role

This position supports the reliability, efficiency, and lifecycle performance of mission-critical mechanical and HVAC systems within hyperscale data centers. It involves applying strong technical knowledge to maintain uptime and long-term system performance.

Responsibilities

• Independently support, inspect, maintain, and troubleshoot mechanical and HVAC systems, including chilled water, DX, airside systems, CRAH/CRAC units, pumps, valves, cooling towers, heat exchangers, and related distribution systems.
• Perform advanced troubleshooting, incident investigations, alarm response, and root cause analysis for mechanical and HVAC equipment or system issues.
• Support and improve mechanical system operation, maintenance procedures, sequences of operation, P&IDs, documentation quality, and operational standards.
• Support capacity planning, retrofits, equipment change-outs, commissioning activities, acceptance testing, and operational handover requirements.
• Partner with site operations teams to improve maintainability, safe execution of work, reliability, efficiency, and lifecycle outcomes for mechanical systems.
• Cook with vendors, service providers, internal engineering teams, and operations stakeholders to support maintenance, repair, testing, and system improvements.
• Use BMS, controls platforms, alarms, trends, and maintenance data to evaluate system performance, identify recurring issues, and recommend corrective actions.
• Review mechanical documentation, maintenance records, drawings, P&IDs, sequences of operation, and vendor materials to support consistent execution across sites.
• Provide field guidance and informal mentoring to less experienced technicians during inspections, maintenance, troubleshooting, and vendor-supported activities.
• Promote safe execution, environmental compliance, refrigerant-handling awareness where applicable, and continuous improvement across mechanical operations.
