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.
