Mechanical Commissioning Technician

ABOUT THE ROLE:

We are seeking a highly skilled Mechanical Commissioning Technician to support the buildout and startup of SpaceXAI's high-performance data centers. In this critical hands-on role, you will perform commissioning, testing, and troubleshooting of mechanical systems that provide cooling, air handling, and fluid distribution for our next-generation AI supercomputing infrastructure.

You will work closely with construction, engineering, and operations teams to ensure safe, reliable, and high-quality mechanical systems from initial installation through full system turnover. This is a full-time, onsite role with significant travel to SpaceXAI data center sites.

RESPONSIBILITIES:

• Execute mechanical commissioning activities for HVAC systems, chillers, cooling towers, CRAC/CRAH units, pumps, heat exchangers, piping systems, and associated controls in data center environments.
• Perform functional testing, airflow and water flow verification, system balancing, and integrated system performance validation.
• Troubleshoot and resolve mechanical, controls, and hydronic issues during pre-commissioning, commissioning, and startup phases.
• Develop and execute detailed commissioning test procedures, checklists, and documentation in accordance with project specifications and industry standards.
• Collaborate with EPC contractors, OEM vendors, and SpaceXAI engineers to coordinate system energization, startup sequences, and integrated system testing.
• Ensure strict adherence to safety protocols, LOTO procedures, and quality standards during all commissioning activities.
• Maintain accurate as-built documentation, test records, and commissioning reports.
• Support training of operations and maintenance teams on commissioned mechanical systems.
• Participate in constructability reviews and provide field feedback to improve design and installation quality.

BASIC QUALIFICATIONS:

• 3+ years of hands-on mechanical commissioning or field technician experience in data centers, power plants, or large industrial facilities.
• Strong working knowledge of data center cooling systems including chillers, cooling towers, pumps, CRAC/CRAH units, and precision air handling.
• Experience with commissioning test equipment (manometers, anemometers, flow meters, temperature/pressure calibrators, etc.).
• Familiarity with relevant codes and standards (ASHRAE, SMACNA, NFPA, ASME, IMC).
• Demonstrated ability to read and interpret mechanical drawings, P&IDs, and control schematics.
• Strong safety mindset with current OSHA 10/30 or equivalent training.
• Willingness to work extended hours, nights, and weekends during critical commissioning windows.

PREFERRED SKILLS AND EXPERIENCE:

• Prior commissioning experience on hyperscale data center projects or mission-critical facilities.
• NEBB, AABC, or equivalent certification in testing, adjusting, and balancing (TAB).
• Experience with BMS/BAS controls troubleshooting and integration (BACnet, Modbus, etc.).
• Knowledge of chilled water systems, refrigerant systems, and high-density liquid cooling technologies.
• Proficiency with commissioning management software (e.g., CxPro, Procore, or similar).
• Technical degree or trade school certification in Mechanical Engineering Technology, HVAC, or related field.

ADDITIONAL REQUIREMENTS:

• Ability to travel extensively to SpaceXAI construction sites and remain onsite during peak commissioning phases.
• Capability to work in industrial environments, climb ladders, lift moderate loads, and wear PPE for extended periods.
