The Senior Commissioning Superintendent is a senior field leader responsible for driving the full-lifecycle commissioning execution of mechanical, electrical, and controls systems on hyperscale data center projects (100MW+). With deep expertise in mission-critical mechanical infrastructure - including chillers, dry coolers, fan coil units, pumps, and HVAC systems - this role owns the field commissioning program from pre-functional testing through Integrated Systems Testing (IST) and owner acceptance. Operating with the authority and credibility of an experienced owner's-side professional, the Sr. Superintendent serves as the on-site commissioning leader, aligning trade contractors, commissioning agents, engineers, and client representatives around a single, accountable execution plan. This role is critical to delivering fully operational, high-availability facilities on schedule and to the highest quality standard.
