Job description

Responsibilities

• Lead pre‑commissioning through Level 5 commissioning for HV, MV, and LV electrical systems, including generators, generator paralleling switchgear, transformers, UPS and battery systems, switchgear, ATS/STS, PDUs, busways, RPPs, grounding, and lighting control, across multiple sites.
• Review and develop the Testing & Verification program with commissioning agents and engineers, confirming every electrical system meets design and operational intent before it goes live.
• Act as the owner's commissioning lead for electrical scope, coordinating general contractors, designers, and vendors across concurrent projects and resolving conflicts before they hit the schedule.
• Run site commissioning end to end: inspections, safety enforcement, progress tracking, and issue resolution from first energization through functional testing.
• Lead the final operational handover, ensuring every electrical system, its test record, and its documentation is ready for live service.

Requirements

• You've personally commissioned HV, MV, and LV electrical systems, generators, switchgear, transformers, UPS, ATS/STS, PDUs, busways, and grounding, at hyperscale or mission‑critical data centers.
• You've run commissioning phases end to end, from factory witness testing and pre‑functional checks through integrated systems testing.
• You've diagnosed and resolved issues during startup under time pressure, and you can trace a fault through a control scheme without waiting for someone else to find it.
• You've coordinated general contractors, designers, and vendors across multiple live projects at once without losing track of open items.
• Test results, punch lists, and commissioning reports are something you maintain as you go, not something you reconstruct after the fact.
• You write clearly enough that a test report or handover package reads as decision‑ready, not just data.
• Bonus: ASHRAE or BCxA commissioning guidelines. NETA test specifications. PLC and EPMS control systems, automatic and semi‑automatic switching schemes. Mechanical systems commissioning exposure.
