## Description

We are seeking a highly skilled Mechanical Commissioning Technician to support the buildout and startup of xAI's high-performance data centres. 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. This is a full-time, onsite role with significant travel to xAI data centre sites.

**Responsibilities:**

- Execute mechanical commissioning activities for HVAC systems, chillers, cooling towers, CRAC/CRAH units, pumps, heat exchangers, piping systems, and associated controls in data centre 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 xAI 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 constructability 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 centres, power plants, or large industrial facilities.

- Strong working knowledge of data centre cooling systems including chillers, cooling towers, pumps, CRAC/CRAH units, and precision air handling.

- Experience with commissioning test equipment (manometers, anemometers, flow meters, temperature/pressure calibrators, etc.).

- 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 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 centre 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.
