About the role

Senior hands-on leadership role responsible for buildout, startup, and handover of mechanical systems for SpaceXSI's high-performance data centers, including commissioning, testing, troubleshooting, and turnover of cooling, air handling, and fluid distribution systems.

Responsibilities

  • Lead and execute all mechanical commissioning activities for HVAC systems, chillers, cooling towers, CRAC/CRAH units, pumps, heat exchangers, piping systems, hydronic loops, and associated controls in hyperscale data center environments.
  • Direct functional performance testing, airflow/water flow verification, system balancing, integrated system testing, and system turnover to operations.
  • Oversee troubleshooting and resolution of complex mechanical, controls, and process issues during pre-commissioning, commissioning, and startup phases.
  • Develop, review, and approve detailed commissioning test procedures, scripts, checklists, and documentation in alignment with project specifications, industry standards, and SpaceXSI requirements.
  • Lead coordination with EPC contractors, OEM vendors, design engineers, and SpaceXSI stakeholders for system energization, startup sequences, and integrated system validation.
  • Mentor, supervise, and provide technical direction to Mechanical Commissioning Technicians and other field personnel; conduct performance feedback and support their development.
  • Champion safety by enforcing strict adherence to LOTO, NFPA, OSHA, and SpaceXSI safety protocols; lead daily safety briefings and job hazard analyses.
  • Maintain comprehensive as-built documentation, test records, issue logs, and final commissioning reports; present readiness reports to senior leadership.
  • Support and deliver training programs for operations and maintenance teams on commissioned systems.
  • Participate in constructability reviews, design feedback sessions, and lessons-learned meetings to continuously improve installation quality and future project execution.
  • Manage commissioning schedules, resources, and punch-list resolution to meet aggressive project timelines.

Qualifications

  • 7+ years of progressive hands-on mechanical commissioning experience in data centers, power plants, semiconductor facilities, or other mission-critical industrial environments, with at least 3 years in a lead or supervisory capacity.
  • Deep expertise in data center cooling systems including large-scale chillers, cooling towers, CRAC/CRAH units, precision air handling, chilled water plants, and high-density liquid cooling technologies.
  • Strong working knowledge of commissioning test equipment (manometers, anemometers, ultrasonic flow meters, pressure/temperature calibrators, power analyzers, etc.).
  • Thorough familiarity with relevant codes and standards (ASHRAE, SMACNA, NFPA, ASME, IMC, LEED, Uptime Institute).
  • Proven ability to read, interpret, and redline mechanical drawings, P&IDs, control schematics, and sequence of operations.
  • Demonstrated leadership experience coordinating multi-discipline teams and managing contractors/vendors in fast-paced construction environments.
  • Current OSHA 30 certification (or equivalent) and strong safety leadership track record.
  • Willingness to travel extensively and work extended hours, nights, and weekends during critical commissioning and startup windows.
