Commissioning Manager

As a Commissioning Manager , you will lead and execute the complete commissioning process for gigawatt-scale data center projects. Operating on behalf of the General Contractor, you will bridge the gap between field construction, trade partners, OEM vendors, third-party Commissioning Agents (CxA), and the client's operations team. You will oversee the testing, functional verification, and site acceptance of complex mission-critical mechanical, electrical, and control systems to ensure zero-downtime performance from pre-commissioning through full operational handover. ABOUT THE ROLE Program Leadership: Drive the site commissioning strategy across all phases (Levels 1 through 5), ensuring strict alignment with client specifications, quality controls, and project delivery schedules. Vendor & Subcontractor Management: Direct and manage subcontractors, equipment vendors (OEMs), and trade partners during startup, energization, Pre-Functional Checklists (PFCs), Functional Performance Testing (FPT), and Integrated Systems Testing (IST). Schedule & Sequence Integration: Develop and integrate commissioning milestones into the master construction schedule, optimizing testing workflows to minimize bottlenecks during high-density equipment turnovers. Issue & Risk Resolution: Lead daily commissioning alignment meetings, maintain real-time deficiency logs, and drive rapid root-cause troubleshooting for complex system failures or performance gaps. Safety & Regulatory Compliance: Enforce strict compliance with Lockout/Tagout (LOTO), Permit-to-Work (PTW), NFPA 70E, and energized work procedures throughout testing phases. Turnover & Documentation: Review and validate third-party Cx reports, Method of Procedures (MOPs), Standard Operating Procedures (SOPs), and final turnover packages to transition facilities to the owner. ABOUT THE CANDIDATE Role Experience: Minimum 3+ years of direct management/leadership experience in a Commissioning Manager role. Mission-Critical Track Record: 8+ years of total experience in MEP construction, start-up, or field testing, with significant exposure to hyperscale or large-scale colocation data center builds. Technical Expertise: Advanced understanding of high-voltage power distribution, medium-voltage switchgear, UPS systems, utility substations, generators, chillers, CRAHs/AHUs, BMS/EPMS, and SCADA systems. Testing Execution: Demonstrated hands-on experience managing Level 4 (Functional Performance Testing) and Level 5 (Integrated Systems Testing / Blackout Testing) for multi-megawatt or gigawatt-scale infrastructure. Education: Bachelor's degree in Mechanical/Electrical Engineering, Construction Management, or equivalent field experience. Certifications (Preferred): CCP (Certified Commissioning Professional), CxA (Commissioning Authority), PMP, or OSHA 30. #J-18808-Ljbffr
