Mechanical Commissioning Technician

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

Requirements

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; 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

Nice to have

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
