Mechanical Commissioning Technician

Responsibilities

• Execute mechanical commissioning activities for chilled-water and condenser-water systems, cooling towers, pumps, heat exchangers, air handlers, computer-room cooling, liquid-cooling equipment, and associated controls in data center environments.
• Perform flush, fill, leak, and pressure tests; verify valve lineups, flow, temperature, and pressure against designs and sequences of operation.
• Complete point-to-point checks with controls technicians and confirm sensors, actuators, interlocks, and alarms respond correctly.
• Troubleshoot mechanical issues during pre-commissioning, commissioning, and startup.
• Develop and execute commissioning test procedures, scripts, and documentation.
• Coordinate startup sequences and integrated system testing with EPC contractors, OEM vendors, and engineers.
• Walk systems against drawings, mark redlines, document punch-list items, and drive deficiency closeout.
• Follow safety protocols, LOTO procedures, and quality standards.
• Maintain as-built documentation, test records, and commissioning reports.
• Support operations and maintenance team training.
• Participate in constructability reviews and provide field feedback.

Requirements

• 3+ years of hands-on mechanical, HVAC, pipefitting, or commissioning experience in data centers, power plants, or large industrial facilities.
• Strong knowledge of chilled-water plants, pumping systems, heat-transfer equipment, and mechanical distribution.
• Experience with commissioning and field test equipment, including pressure gauges, flow meters, temperature instruments, and leak-detection tools.
• Ability to read and interpret P&IDs, mechanical drawings, and equipment submittals.
• OSHA 10/30 or equivalent safety training.
• Willingness to work extended hours, nights, and weekends during critical commissioning windows.
• Ability to travel extensively, remain onsite during peak commissioning phases, work in industrial environments, climb ladders, lift moderate loads, and wear PPE for extended periods.

Nice-to-Haves

• Commissioning experience on hyperscale data center or mission-critical facility projects.
• Experience with liquid-cooling distribution, cooling towers, and primary/secondary pumping.
• Familiarity with building-management or industrial-control sequences.
• EPA Section 608 refrigerant certification.
• Technical degree or trade-school certification in Mechanical Engineering Technology, HVAC, or a related field.
• Proficiency with commissioning management software such as CxPro or Procore.

Compensation and Benefits

• Full-time, onsite role with significant travel to data center sites.
