Job description

About Prime Data Centers

Prime Data Centers develops, acquires, and operates data centers for some of the world's largest enterprises. A private firm owned by a group controlling $6 billion in assets, with a 15-year tenure in technology and real estate development, Prime provides customers with ownership options and dynamic leasing models, defining a true corporate partnership.

About the role

The Commissioning (Cx) Program Engineer, CxE, is the project-level administrator of Prime's global commissioning program across a regional portfolio. The CxE owns the entire commissioning lifecycle for each project in the designated region, from RFP to turnover.

As the is an owner's-representative, the CxE will be executing testing on site, enforcing the standards, govern the commissioning lifecycle, integrate commissioning with construction and design teams, and drive third-party commissioning agents (CxAs) and project teams toward on-time, defect-free turnovers to Operations.

The CxE will be accountable for the management, quality, schedule, and closeout of commissioning processes. This role will also be part of the global commissioning team, coordinating closely with leadership and the other regional CxEs to drive success. Prime is strategically placing Cx management personnel in each of its domestic development hubs: Denver, Phoenix, Chicago, Dallas, and Austin.

What you'll do

• Enforce Prime's commissioning standards, templates, and processes — including commissioning plans, installation and pre-functional checklists, functional performance tests, IST scripts, and issues/closeout logs.
• Coordinate closely with leadership to refine corporate standards and processes.
• Own and oversee the L2–L5 commissioning lifecycle framework for the campus.
• Be an expert on project specifics and requirements, ensuring each project is scoped and executed properly.
• Develop and execute contracts for Cx services from RFP development, budgeting, and scheduling through completion and turnover. Analyze and approve change orders and equipment costs.
• Integrate with Prime’s Quality department to support assurance and consistency.
• Support other CxEs and projects, occasional travel to other campuses and to the Denver Office.
• Establish and track program-level KPIs (schedule adherence, issue resolution rates, turnover quality, etc.) and perform regular reporting to leadership.
• Monitor and support the project through its entire lifecycle from a commissioning perspective: contractor and vendor selection, drawing package development, equipment selection and procurement, etc.
• Provide oversight and technical direction to project teams, contractors, and third-party CxA vendors across multiple simultaneous projects.
• Integrate the commissioning schedule with design, procurement, and construction milestones; identify and mitigate schedule risks before they affect commissioning or turnover.
• Oversee pre-functional and functional testing of MEP systems and lead/govern integrated systems testing (IST), including failure-mode and load-bank scenarios, utility-loss simulations, UPS/generator/ATS switchovers, cooling-plant sequencing, and BMS/EPMS responses, etc.
• Drive issues identification, triage, and resolution to closure; ensure root-cause tracking rather than symptomatic fixes. Contribute to and maintain Lessons Learned documentation, with frequent revisiting and presentations to leadership and other project teams.
• Scope, select, onboard, and manage third-party CxA providers in coordination with leadership; track, review, and approve deliverables, schedules, testing scripts, and reports. Direct and course-correct as necessary to adhere to schedule, budget, and quality expectations.
• Serve as the commissioning point of contact for construction/development teams, design engineers, contractors, equipment vendors, and customers, as applicable.
• Coordinate with the site Operations teams to ensure a clean handover, training, and operational readiness.
• Ensure complete, auditable commissioning documentation and final Cx reports for each project.
• Own closeout and turnover packages; confirm operations training and as-built/record documentation are in place before handover.
• Support commissioning budgeting, forecasting, and cost controls across the program.
• Contribute to strategic planning to build, mentor, and scale the commissioning team as the company grows.

Qualifications

• Working knowledge of the full L0–L5 mission critical commissioning lifecycle.
• Strong command of/subject matter expertise in mission-critical MEP systems — power distribution, UPSs, generators, switchgear/ATSs, chilled-water and air/liquid cooling systems, controls (BMS/EPMS), and fire/life safety, etc.
• Ability to read and interpret construction drawings, specifications, sequences of operations, and contracts.
• Familiarity with applicable standards, codes, and best practices (e.g., ASHRAE, NEC/NFPA, etc.).
• Excellent written and verbal communication; able to lead triage calls, present status to leadership, and hold vendors accountable.
• Comfort executing responsibilities in a professional leadership role while acting as a representative of Prime.
