SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today, SpaceX is actively developing the technologies to make this possible, with the ultimate goal of making life multiplanetary and expanding consciousness to the stars.
SpaceXSI is building Super Intelligence to help humanity understand the universe. Our teams are building the full Super Intelligence stack: from our Colossus supercomputers, to Grok models, to our suite of applications, including Grok Bot, Grok Build, Grok Imagine, Grok Voice, and X. We're creating a powerful flywheel where more compute trains better models, better models power more useful products, and what we learn from people using those products shapes what we build next.
MECHANICAL COMMISSIONING TECHNICIAN
We are seeking a highly skilled Mechanical Commissioning Technician to support the buildout and startup of SpaceXSI'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.
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 SpaceXSI 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 constructibility 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 industrial facilities
- Experience with commissioning test equipment (manometers, anemometers, flow meters, temperature/pressure calibrators, etc.)
- Current OSHA 10/30 certification or equivalent training
PREFERRED SKILLS AND EXPERIENCE:
- Strong working knowledge of data center cooling systems including chillers, cooling towers, pumps, CRAC/CRAH units, and precision air handling
- 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
- 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 SpaceXSI 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
- Willingness to work extended hours, nights, and weekends during critical commissioning windows
- This is a full-time, onsite role with significant travel to SpaceXSI data center sites
