Commissioning Site Mechanical Lead, Data Centers

Role Scope

• Lead mechanical commissioning across flushing, cooling, heat rejection, and liquid cooling systems for high performance data centers, spanning Level 1 through Level 5 commissioning phases.
• Drive the Testing & Verification program for mechanical cooling, heat rejection, and data hall thermal systems, working with commissioning agents and engineers from pre-site testing through on-site functional testing.
• Own commissioning documentation across multiple projects and sites, tracking issues, test results, and reports with enough rigor to hold up under an owner audit.
• Run on-site commissioning operations across general contractors, designers, and vendors: inspections, safety enforcement, progress tracking, and issue resolution.
• Close out final operational handover for mechanical systems, confirming every system is ready for service before occupancy.

Requirements

• Minimum of 10 or more years of hands-on commissioning experience.
• Commissioned data center mechanical equipment firsthand: chillers, cooling towers, CRAH/CRAC units, AHUs, CDUs, direct-to-chip liquid cooling, pumps, hydronic piping, and BMS/BAS integration.
• Run hydronic flushing, cleaning, and pressure and hydrostatic testing on process piping.
• Know AABC/NEBB TAB standards well enough to catch a bad test result before it gets signed off.
• Built and executed Testing & Verification programs end to end, from pre-site functional testing through on-site startup, troubleshooting, and support.
• Show up in design and constructability reviews with commissioning and operations in mind, catching issues before they're built into concrete and steel.
• Keep commissioning records, issue logs, and test reports rigorous enough that any of them could stand up to an owner or insurer audit.
• Hold a degree in Mechanical Engineering.

Nice-to-Haves

• ASHRAE or BCxA commissioning guideline experience.
• Controls or electrical systems knowledge.
• Hyperscale or mission-critical data center project experience.
• Managing multiple concurrent project sites.
