## Description

SpaceXAI is seeking a highly skilled Mechanical Commissioning Technician to support the buildout and startup of its high-performance data centers.

In this critical hands-on role, you will perform commissioning, testing, and troubleshooting of mechanical systems that cool and support SpaceXAI's next-generation AI supercomputing infrastructure.

**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.
