Mechanical Commissioning Technician

Job Overview

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.
