• Conduct pre-functional inspections, functional performance testing, integrated systems testing, heat-load testing, scenario testing, and network diagnostic activities.
• Troubleshoot mechanical equipment and system issues, document findings, and coordinate corrective actions with contractors, vendors, controls teams, and other stakeholders.
• Act as the primary commissioning point of contact for mechanical infrastructure, controls, and monitoring systems throughout project delivery.
• Develop detailed SOPs and Methods-of-Procedures and compile project documentation into comprehensive, site-specific Systems Manuals.
• Coordinate multiple commissioning activities, schedules, resources, and stakeholders while maintaining strong project communication and technical quality.
• Support proposals, team planning, budget management, and the preparation of detailed commissioning reports using QA/QC and project platforms such as BIM360, CxAlloy, and Facility Grid.

Requirements

• Minimum 5 years of documented experience in data center and/or mission-critical commissioning, ideally including greenfield projects of 25MW or greater.
• Demonstrated experience with third-party commissioning of controls and automation systems, chillers, cooling towers, CDUs, CRAHs, CRACs, RTUs, and AHUs.
• Strong understanding of mechanical commissioning methodologies, critical infrastructure, system testing, and facility performance validation.
• Experience with high-density liquid cooling systems is highly desirable.
• Strong project management and coordination capabilities, with the ability to manage multiple concurrent commissioning activities and maintain effective stakeholder relationships.
• Excellent written and verbal communication skills and the ability to communicate technical information clearly to diverse audiences.
