Commissioning Manager - Mission Critical

GCON is seeking an experienced Commissioning Manager to oversee the planning, execution, and delivery of full L1–L5 commissioning programs for complex, hyperscale mission-critical projects. 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.
• Demonstrated expertise leading L3 functional testing and L4 integrated systems testing (IST) on hyperscale or enterprise-scale data center facilities.
• Proven experience managing L5 full facility acceptance testing under IT load for Tier III/IV or equivalent hyperscale environments.
• Bachelor's degree in Construction Management, Engineering, or a related technical field.
• Deep knowledge of MEP and critical infrastructure systems commissioning, including level-specific test procedures, deficiency tracking, and resolution workflows.
• Strong leadership skills, with the ability to align cross-functional teams and third-party commissioning agents across concurrent commissioning levels on fast-track schedules.
• Ability to analyze, troubleshoot, and resolve complex system interactions — particularly during L4 IST scenarios — under tight deadlines.
• Excellent client-facing communication skills, with experience presenting level-completion reports and commissioning status to owners and technical stakeholders.

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.
• Experience managing concurrent L3/L4 testing across multiple buildings or power blocks within a single campus program.

The GCON Way

• Work with a forward-thinking, collaborative team that embraces technology and innovation.
• Be part of a leading construction manager building cutting-edge data center facilities.
• Competitive compensation.
• 100% employee medical/dental premium coverage (generous family coverage with 3 plans to tailor to needs).
