Sr. Commissioning Manager

Mission Critical Hyperscaler

Reports to: Sr. Director / Program Director, Mission Critical

Req ID: 12332

Position Summary

The Sr. Commissioning Manager leads the full commissioning program on hyperscale data center construction, from construction turnover through L1–L5 integrated systems testing and client Final Handover (FHO).

Responsibilities include driving the commissioning schedule as a contractual deliverable, managing the Cx risk register, leading L1 through L5 test execution across electrical and mechanical systems, and serving as Barton Malow's primary technical interface with the client's Commissioning Authority (CA).

The Sr. Commissioning Manager leads the Cx schedule integrated into the program's P6 schedule, manages FOD protocols and energization sequencing, drives ROMP milestone readiness, and is accountable for Certificate of Readiness (COR) deliverables at each client milestone gate.

Key Job Responsibilities

• Leads the commissioning staffing plan, Cx schedule, and budget for the full program. Recruits, assigns, and evaluates Cx Engineers and field technicians across multiple simultaneous buildings.
• Develops and maintains the master Commissioning Execution Plan (CEP) per building, integrated with the P6 program schedule. Leads all critical path activities from systems completion through Final Handover (FHO).
• Manages the Cx risk register across the program. Escalates schedule or technical risks to the Program Director and client Commissioning Authority (CA) with mitigation plans and recovery dates.
• Leads and executes L1 through L5 commissioning testing across all electrical and mechanical systems, including generator load bank testing, UPS paralleling, STS/ATS transfer testing, chiller plant sequencing, and BMS/EPMS integration verification, and client-witnessed Integrated Systems Tests (ISTs).
• Manages Pre-Startup Safety Reviews (PSSRs) and client acceptance walks at each ROMP milestone gate. Delivers Certificate of Readiness (COR) packages per client milestone requirements (NEA, H2C, pFHO, FHO).
• Coordinates all CFCI/OFCI equipment commissioning with OEM field service engineers. Manages OEM scheduling, witness testing, and documentation acceptance.
• Leads the building energization sequence plan. Develops step-by-step energization procedures for each distribution tier (utility, MSB, switchgear, UPS, PDU, busduct). Manages FOD inspections at all energization hold points; no energization proceeds without Cx Manager sign-off.
• Manages arc flash boundary controls and PPE requirements for all energization activities. Coordinates with the Owner's Authority Having Jurisdiction (AHJ) for utility interconnection approvals.
• Develops and maintains the Project Specific Commissioning Manual (PSCM), building-level Cx Test Packages, and all punch list documentation within the client-approved Cx management platform (Procore Cx, Cx Alloy, or owner-specified tool).
• Publishes a weekly Cx Schedule Look-Ahead (3-week) aligned to the P6 program schedule. Tracks Cx completion percentages by system and building against ROMP milestones and reports status in client-facing weekly meetings.
• Manages all commissioning records, including accurate red-line/as-built drawings, test reports, OEM startup records, exception logs, and COR packages, all uploaded to the client system of record before milestone gate closure.
• Serves as Barton Malow's primary Cx interface with the hyperscaler client's Commissioning Authority (CA) and Mission Critical Operations team. Leads the weekly Cx workstream status report to the client and participates in client scorecard reviews, responding to CA technical comments within 48 hours.
• Leads systemization using building-specific single-line diagrams, equipment schedules, and BMS/EPMS sequences of operation. Defines system boundaries, assigns system numbers, and manages system turnover packages from construction to Cx.
• Ensures a documented, zero-punch-list-at-gate turnover from construction to commissioning, with gate criteria defined in the PSCM and enforced at L1 system acceptance.
• Leads daily field-level Cx standups and weekly executive Cx meetings. Distributes meeting minutes with named owners, due dates, and RAG status within 24 hours, and manages the open action item log between Barton Malow, subcontractors, OEMs, and the client CA.
• Collaborates with the Project Controls lead to incorporate Cx milestone dates into the program's P6 schedule and GCA contractual milestone tracking, flagging delay risk to critical path ROMP milestones within 48 hours of identification.

Required Knowledge, Education, Experience, Skills, and Abilities

• Bachelor of Science in Electrical Engineering, Mechanical Engineering, or a related discipline; or 10+ years of mission critical commissioning experience with demonstrated hyperscale data center program delivery.
• Minimum of 3 hyperscale data center programs (100MW+ campus or equivalent) as Cx Manager or Sr. Cx Engineer, including at least one Tier III or Tier IV facility through client Final Handover (FHO).
• Expert-level knowledge of mission critical electrical systems: medium voltage distribution, generators, UPS, static transfer switches, PDUs, and busduct. Working knowledge of mechanical systems: chilled water plants, CRAH/CRAC units, cooling towers, and BMS/EPMS.
• Proficiency with commissioning management platforms (Procore Cx, Cx Alloy, or equivalent owner-specified tool). Ability to read and interpret single-line diagrams, P&IDs, sequences of operation, and protection relay settings.
• Familiarity with hyperscaler client commissioning standards and ROMP milestone frameworks, with direct experience navigating client Commissioning Authority review and acceptance processes.
• Current OSHA 30 Safety Training certificate and NFPA 70E Arc Flash Safety certification required. RCDD, CEM, or BICSI Data Center Design certifications preferred. P6 scheduling proficiency preferred.

Work Environment / Job Conditions

• Program-based assignment structure with full-time on-site presence required during active commissioning phases, supporting concurrent commissioning activities across 2+ buildings on a multi-building hyperscale campus.
• Field-dominant during L1–L5 test execution phases and office-based during planning and documentation windows. Appropriate field attire is required for hot and cold environments.
• Candidates must be comfortable working in energized electrical environments and comply with all site-specific PPE and arc flash boundary requirements at all times.
