Role summary

SpaceXAI is hiring a Mechanical Commissioning Technician for their high-performance data centers. This hands-on role involves commissioning, testing, and troubleshooting mechanical systems for AI supercomputing infrastructure. Responsibilities include executing tests on chilled water, condenser water, cooling towers, pumps, and liquid-cooling equipment, verifying system performance against design, and collaborating with various teams to ensure system reliability and quality. The role requires 3+ years of relevant experience, strong knowledge of HVAC and mechanical systems, and the ability to read technical drawings. This is a full-time, onsite position with significant travel and requires a strong safety focus.

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

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 cool and support 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 chilled water, condenser water, 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 lineup, flow, temperature, and pressure against design and sequence of operations.
  • Complete point-to-point checks with controls technicians and confirm sensors, actuators, interlocks, and alarms respond correctly.
  • Troubleshoot and resolve mechanical issues during pre-commissioning, commissioning, and startup phases.
  • Develop and execute detailed commissioning test procedures, scripts, and documentation in accordance with project specifications and industry standards.
  • Collaborate with EPC contractors, OEM vendors, and SpaceXAI engineers to coordinate startup sequences and integrated system testing.
  • Walk systems against drawings, mark redlines, write punch-list items, and drive closeout until deficiencies are cleared.
  • 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, HVAC, pipefitting, or commissioning experience in data centers, power plants, or large industrial facilities.
  • Strong working knowledge of chilled-water plants, pumping systems, heat transfer equipment, and related mechanical distribution.
  • Experience with commissioning and field test equipment (pressure gauges, flow meters, temperature instruments, leak-detection tools, etc.).
  • Ability to read and interpret piping and instrumentation diagrams, mechanical drawings, and equipment submittals.
  • 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.
  • 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 (e.g., CxPro, Procore, or similar).

    • 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.

    • SpaceXSI is an equal opportunity employer. For details on data processing, view our Recruitment Privacy Notice.
