Responsibilities
- Develop the project‑specific pre‑commissioning and commissioning plan for each container, including scope, milestones, resource plan, and dependencies across civil, electrical, mechanical, and IT workstreams.
- Participate in design reviews to ensure commissioning requirements (valving, test points, bypasses, sensor placement, drain/fill points) are incorporated into the container and rack designs.
- Lead pre‑functional checks and functional performance tests for liquid cooling circuits and air-cooled systems.
- Lead commissioning of control systems including BMS/BAS, DTC loop controls, CDU logic, leak detection, and alarm / interlock strategies for both liquid and air‑cooled domains.
- Plan and execute integrated systems testing (IST) to validate start‑up, normal operation, failover (e.g., pump or fan failures, power events), emergency shutdown, and recovery across power, cooling, and IT subsystems.
- Support IT workload testing, monitoring thermal and power telemetry to identify any infrastructure bottlenecks, derates, or instability under realistic AI workloads.
- Develop and maintain commissioning procedures, scripts, checklists, and test forms tailored to the container architecture, and combined liquid/air environment.
- Maintain detailed commissioning logs, punch lists, and issue registers; drive root‑cause analysis and corrective actions with responsible contractors and vendors.
- Compile and approve final commissioning deliverables including as‑built documentation, calibrated setpoints, test reports, and handover packages for operations, and deliver training for the customer's operations staff.
