At least 4 years of direct field experience executing or managing commissioning in a hyperscale data center, mission-critical facility, heavy industrial environment, or similar setting.
Working knowledge of large-scale electrical delivery systems, including UPS, switchgear, and generation, and mechanical cooling systems, including chilled water plants, hydronics, and CRAH/CRAC units.
Experience directing or overseeing onsite Level 3 (Pre-Functional), Level 4 (Functional Performance Testing), and Level 5 (Integrated Systems Testing) activities.
Ability to read, interpret, and field-verify MEP drawing packages, Single-Line Diagrams, and Sequences of Operation.
Experience managing onsite vendors, contractors, or specialized testing firms.
Ability to work onsite daily at the assigned data center location.

Nice To Haves

Previous experience as a dedicated onsite Commissioning Engineer or Resident Engineer for a major data center build or campus expansion.
Industry-recognized commissioning certification such as Certified Commissioning Authority (CxA), Certified Commissioning Professional (CCP), or Building Commissioning Professional (BCxP).
Hands-on experience with commissioning management software such as CxAlloy, Facility Grid, or similar tools for field tracking and issue management.
Practical field experience troubleshooting Building Automation Systems (BAS), Direct Digital Control (DDC), and Electrical Power Monitoring Systems (EPMS).
Strong understanding of field safety standards, including OSHA/NFPA 70E, MOP execution, and hazardous energy control.
Demonstrated ability to identify field coordination clashes, resolve complex physical engineering challenges, and provide continuous-improvement feedback to global engineering teams.
Proficiency with AI tools to enhance daily work, including AI-assisted field report summarization, automated submittal parsing, and punch-list tracking.

Responsibilities

Serve as the primary onsite Apple commissioning representative for an assigned data center campus and drive day-to-day commissioning lifecycle execution (Levels 1–5).
