Commissioning Manager

We’re looking for a seasoned Commissioning Manager (Owner’s Representative) to take a lead role overseeing commissioning on high-stakes, mission-critical data center projects. In this role, you’ll act as the Owner’s trusted authority—guiding the commissioning process from early design through final turnover, ensuring every system performs exactly as intended. #commissioning, #buildingservices, #MissionCritical, #MEP, #OwnersRep, #QAQC 

This is a highly visible, high-impact position where your technical judgment, leadership presence, and decision-making will directly influence project success, operational readiness, and long-term reliability. Enjoy a rare industry advantage, this role offers straight-time overtime pay, so every extra hour you work boosts your earnings. 

Why This Role Stands Out 

• Own the outcome – Serve as the final voice for commissioning process and quality on complex data center builds 

• Work at the cutting edge – Engage with advanced electrical and mechanical systems in mission-critical environments 

• Lead without hierarchy – Influence top-tier contractors, engineers, and commissioning professionals 

• Make a lasting impact – Ensure uptime, resilience, and operational excellence for critical infrastructure 

• High exposure – Interface with senior leadership and shape project delivery strategy  

What You’ll Do 

• Act as the Owner’s commissioning single point of authority, providing independent oversight across design, construction, testing, and turnover 

• Ensure all systems meet Owner Project Requirements (OPR), design intent, and performance standards 

• Review and approve commissioning plans, test scripts, schedules, and documentation before execution 

• Witness commissioning activities from installation through integrated systems testing (L2–L5) 

• Identify risks early, escalate issues, and drive resolution to maintain schedule and quality 

• Represent commissioning interests in project meetings and decision-making forums 

• Confirm readiness for turnover, including documentation, training, and deficiency resolution 

What We’re Looking For 

You’re a confident technical leader who thrives in high-stakes environments. You bring a strong sense of ownership and aren’t afraid to challenge assumptions or push for the right outcome. 

• Independent thinker with strong technical judgment 

• Comfortable influencing contractors, engineers, and commissioning agents 

• Detail-oriented with the ability to see the big picture 

• Driven by quality, uptime, and long-term operational success 

• Strong communicator across both technical teams and executive stakeholders 

Qualifications 

• Bachelor’s degree in Engineering, Construction Management, or related technical field (or equivalent experience) 

• Commissioning certification preferred (ACG CxA, BCxP, CCP) 

• NFPA 70E and OSHA 30 (or ability to obtain) 

• PMP or Uptime Institute certifications are a plus 

• Valid driver’s license  

• Ability to travel up to 75% 

Experience 

• 12+ years in commissioning, construction, or operations within critical infrastructure environments 

• Experience in industries such as data centers, power generation, healthcare, pharmaceuticals, petrochemical, or similar 

• Proven track record overseeing commissioning or high-reliability systems 

• Hands-on exposure to startup, testing, and performance validation 

• Military technical experience or equivalent high-consequence environments welcomed 

Technical Responsibilities 

• Oversee performance of electrical systems and testing (switchgear, UPS, generators, ATS/STS, power distribution) 

• Oversee performance of mechanical systems and testing (chilled water plants, CRAH/CRAC units, building automation systems) 

• Assess functional performance and integrated systems testing for completeness and accuracy 

• Ensure alignment with industry standards such as ASHRAE, NFPA, and Uptime Institute guidelines 

• Review system interactions, failure modes, and operational readiness scenarios 

Management, Supervision, and Guidance 

• Provide functional leadership across the commissioning process without direct reports 

• Monitor the work of commissioning agents, contractors, and startup teams to provide backup and risk analysis for the team 

• Hold all parties accountable for delivering high-quality, compliant results 

• Serve as the escalation point for commissioning-related risks and decisions 

Communication, Teamwork, and Leadership 

• Deliver clear, timely updates on commissioning progress, risks, and outcomes 

• Facilitate alignment among owners, contractors, engineers, and third-party teams 

• Lead discussions that balance technical detail with business priorities 

• Confidently present findings and recommendations to senior leadership 

• Build strong working relationships while maintaining objective oversight 

Why This Role 

This is more than a commissioning role; it’s a chance to shape how mission-critical facilities come to life. You’ll be trusted to make decisions that directly impact system reliability, performance, and long-term success. 

If you’re looking for a role where your expertise is respected, your voice carries weight, and your work truly matters, this is your opportunity to lead from the front.
