Job description

Lead mechanical systems readiness for new capacity and ongoing reliability. Provide commissioning oversight, drive new site onboarding and transition, and execute site inspections/audits to uncover performance, efficiency, and reliability risks across chilled-water plants, CRAH/CRAC, cooling towers, heat-rejection systems, and controls/BMS. Ensure mechanical designs meet operational standards and that documentation and training are complete for Day 1 operations.

Responsibilities

• Commissioning oversight:Validate mechanical system performance and control sequences; track and close defects/punch-list items discovered pre-commissioning and during commissioning.
• Develop and conduct commissioning for infrastructure projects that are executed at operational datacenters.
• Conduct operational procedure validation during post turnover pre customer load deployment phase.
• Support the development of a robust process to standardize mechanical turnover documentation, ensure storage in the designated repository, and verify operator training and readiness.
• Site inspections / audits: Conduct site physicals and infrastructure assessments focused on mechanical reliability, efficiency, and risk; maintain and drive closure of mitigation plans.
• Design-to-operations bridge: Document field changes, communicate operational impacts to the gaining team, and ensure readiness gaps are closed prior to hand-off.
• Cross-functional coordination: Work with Design & Construction, Commissioning, Site Operations, and Reliability Engineering to align standards and continuously improve readiness playbooks.
• Provides continual evaluation of processes and procedures, responsible for suggesting methods to improve operation and efficiency of DC design and equipment.
