About the role
LotusWorks is seeking an experienced and safety-focused Senior Data Center Commissioning Manager to lead the end-to-end commissioning program for a major data center project in Grafton, Wisconsin. This role will be responsible for planning, executing, documenting, and turning over the commissioning program while ensuring MEP, controls, electrical, and life-safety systems perform in accordance with the Basis of Design (BOD), Owner’s Project Requirements (OPR), and project requirements. The Senior Data Center Commissioning Manager will own the end-to-end commissioning program for the facility — planning, execution, documentation, and turnover — and is the single point of accountability that the MEP, controls, and life-safety systems perform to the Basis of Design and OPR before the operations team accepts them.

•
Coordinate with the BMS/EPMS integrator on point-to-point, trending, alarms, and graphics verification
Quality and documentation
•
Own the Cx issues log through closure; verify corrective work rather than accepting contractor sign-off

•
Verify O&M manuals, as-builts, training, and warranty documentation are complete before turnover
