Data Center Commissioning Technician

We are seeking a senior-level Data Center Commissioning Technician with deep expertise in UPS systems, critical power infrastructure, and large-scale load testing. This is not a preventative maintenance or parts replacement role. This position requires a commissioning professional who can lead testing events, interface confidently with general contractors and clients, and execute high-risk power transitions in live environments.

The ideal candidate has completed multiple full data center commissioning projects, understands commissioning levels (L2 L5), and has hands-on experience executing MW-scale load bank testing and generator-to-UPS transfers under load.

Key Responsibilities

Lead and execute data center commissioning activities (Levels L2 L5)

Perform and oversee large-scale load bank testing (500kW to 1MW+)

Execute generator-to-UPS transfer testing under live load

Commission and validate parallel redundant UPS systems (N+1, 2N)

Perform static and maintenance bypass transitions without load disruption

Conduct closed-transition generator testing

Validate synchronization (voltage, frequency, phase alignment)

Commission lithium-ion and VRLA battery systems

Perform battery discharge testing and string balancing verification

Identify and troubleshoot DC ground faults and bypass events under load

Integrate UPS systems with BMS / EPMS platforms

Execute commissioning from approved MOPs; redline and update documentation

Ensure compliance with ISO, NFPA, and NEC standards

Enforce safety standards and stop work when unsafe conditions arise

Lead multi-stakeholder commissioning events ( EC, CxA, client)

5+ years of UPS field service experience

3+ years specifically in commissioning

Completion of at least 3 full data center commissioning projects

Experience executing load bank tests above 500kW (1MW+ preferred)

Experience with generator-to-UPS transfers under load

Experience working in live data center environments

Demonstrated ability to lead commissioning events
