This role is ideal for a seasoned professional from a general contracting background who excels at managing multi-disciplinary commissioning teams, complex MEP systems, and high-stakes project delivery across all commissioning levels.
As the Commissioning Manager, you will own the end-to-end commissioning process • from preconstruction strategy through L5 integrated systems testing and final owner acceptance. You'll coordinate across project teams, trade partners, clients, and third-party commissioning agents to ensure all systems perform to the highest standards of reliability, redundancy, and compliance at every commissioning level.
Key Responsibilities - Lead the full L1• L5 commissioning program for multiple large-scale hyperscale data center projects, encompassing mechanical, electrical, plumbing, controls, and specialty systems across every phase of commissioning rigor.
- Develop and implement comprehensive commissioning plans, schedules, and level-gate workflows for all phases • L1 component verification, L2 pre-functional checks, L3 functional performance testing, L4 integrated systems testing (IST), and L5 full facility/IT load testing through final turnover.
- Define level-entry and level-exit criteria for each commissioning phase, ensuring no system advances without meeting documented readiness standards.
- Manage and coordinate multi-disciplinary teams • including project managers, superintendents, subcontractors, and third-party commissioning agents • aligning all stakeholders to commissioning level milestones and critical path gates.
- Oversee risk management and recovery strategies for schedule, system readiness, and critical path impacts at each commissioning level, with particular focus on protecting L4/L5 integrated testing windows.
- Ensure quality assurance, code compliance, redundancy requirements (N, N+1, 2N), and system reliability are validated through structured level-by-level progression.
- Lead client-facing meetings and gate reviews at each commissioning level, providing technical expertise, issue logs, and level-completion reporting to owners and third-party agents.
- Partner with preconstruction teams to develop L1• L5 commissioning strategies during design review, anticipating system sequencing challenges and optimizing testing workflows for hyperscale build schedules.
- Drive continuous improvement by standardizing level-gate documentation, integrating digital commissioning tools, and mentoring project teams on hyperscale commissioning best practices.
- Manage final L5 acceptance and project turnover, including complete commissioning documentation packages, owner training, and lessons learned across all commissioning levels.
Required Skills & Experience - 8• 10+ years of commissioning experience on mission-critical or data center projects with a general contractor, including hands-on delivery of L1 through L5 commissioning scopes.

Preferred Qualifications - Direct experience delivering L1• L5 commissioning programs for hyperscale clients (e.g., AWS, Microsoft, Google, Meta) at gigawatt-scale campus or multi-building facilities.
- Familiarity with hyperscale owner commissioning standards and how they map to internal L1• L5 level structures.
- Proficiency with Primavera P6, Procore, BIM 360, and commissioning management platforms capable of tracking level-gate status across large systems counts.
- Working knowledge of ASHRAE Guideline 0, NEBB, and BCA standards as they apply to structured commissioning level progression.
