Job description

Our client is a national leader in NETA testing, commissioning, and staff augmentation for the mission-critical industry. They are adding a Mechanical Commissioning Manager in Montgomery, AL to own the mechanical commissioning scope on data center projects, from design review through integrated systems testing and turnover.

This is a hands-on leadership role for someone who knows how cooling plants work, how they fail, and how to prove they wont. If you came up through Navy Nuclear as a mechanical rate or hold a Mechanical Engineering degree, and you've already commissioned data centers, this one is worth a conversation.

WHAT YOU'LL DO

• Lead mechanical commissioning across Levels 1-5: factory witness testing, installation verification, pre-functional checks, functional performance testing, and integrated systems testing (IST).
• Review mechanical design documents, submittals, and sequences of operation for commissionability, redundancy, and owner project requirements.
• Build and execute commissioning plans, checklists, and functional test scripts for chilled water plants, chillers, cooling towers, CRAHs/CRACs, air handlers, pumps, heat rejection, and liquid cooling systems.
• Verify BMS/controls sequences, alarms, and failover behavior with controls contractors, and confirm TAB results against design.
• Run commissioning meetings and coordinate daily with the GC, mechanical trades, owner representatives, and the electrical commissioning team.
• Track issues to closure in the commissioning issues log (CxAlloy, BlueRithm, or similar) and hold trades accountable to schedule.
• Lead and mentor mechanical commissioning technicians and agents on site.
• Produce test documentation, commissioning reports, and turnover packages the owner can operate from.
• Set the standard for site safety, including LOTO and energized-equipment procedures.

WHAT YOU BRING

• A strong mechanical background from one of these paths: U.S. Navy Nuclear Propulsion Program in a mechanical rate (e.g., Machinist's Mate - Nuclear), or a Bachelor's degree in Mechanical Engineering.
• Data center commissioning experience. This is required.
• Working knowledge of chilled water systems, HVAC equipment, controls, and TAB in a mission-critical environment.
• Experience writing and running functional test scripts and leading IST events.
• Ability to lead multi-trade teams and hold a jobsite to a schedule.
• Clear written reporting and comfort presenting results to owners and GCs.
• Ability to work on site in Montgomery, AL.

NICE TO HAVE

• Commissioning certification (CxA, CCP, BCxP, or similar), or PE/EIT.
• Hyperscale or colocation project experience.
• Familiarity with ASHRAE Guideline 0 and 1.1 and Uptime Institute tier concepts.
• Working knowledge of electrical commissioning and how it ties to mechanical IST.
• OSHA 30.

SCHEDULE & BENEFITS

• 5-10s schedule (five 10-hour days), with 10 hours of overtime every week.
• Per diem paid 7 days per week.
• 15 days of PTO.
• Full medical benefits.
• Major holidays paid, plus a floating holiday and Veterans Day.
