## Description

SpaceXAI is seeking a Mechanical Commissioning Engineer to execute the buildout, startup, and handover of mechanical systems for its high-performance data centers.

You will work closely with construction, engineering, operations, EPC contractors, and OEM vendors to deliver safe, reliable, and high-quality mechanical systems.

## Responsibilities:

- Execute all mechanical commissioning activities for HVAC systems, chillers, cooling towers, CRAC/CRAH units, pumps, heat exchangers, piping systems, hydronic loops, and associated controls in hyperscale data center environments.

- Execute functional performance testing, airflow/water flow verification, system balancing, integrated system testing, and system turnover to operations.

- Troubleshoot and resolve complex mechanical, controls, and process issues during pre-commissioning, commissioning, and startup phases.

- Develop and review detailed commissioning test procedures, scripts, checklists, and documentation in alignment with project specifications, industry standards, and SpaceXAI requirements.

- Coordinate with EPC contractors, OEM vendors, design engineers, and SpaceXAI stakeholders for system energization, startup sequences, and integrated system validation.

- Champion safety by enforcing strict adherence to LOTO, NFPA, OSHA, and SpaceXAI safety protocols; participate in daily safety briefings and job hazard analyses.

- Maintain comprehensive as-built documentation, test records, issue logs, and final commissioning reports.

- Support and deliver training programs for operations and maintenance teams on commissioned systems.

- Participate in constructability reviews, design feedback sessions, and lessons-learned meetings to continuously improve installation quality and future project execution.

- Support commissioning schedules and punch-list resolution to meet aggressive project timelines.

## Basic Qualifications:

- Bachelor’s degree in STEM degree or trade school certification in Mechanical Engineering Technology, HVAC, or a related field

- 1+ years of hands-on mechanical experience in HVAC, commissioning, testing, construction, or a related field (data centers, power plants, semiconductor facilities, commercial buildings, or other industrial environments).

## Preferred Skills and Experience:

- Expertise in mechanical cooling and air-handling systems, including chillers, cooling towers, CRAC/CRAH units, precision air handling, chilled water plants, and/or high-density liquid cooling.

- Working knowledge of commissioning test equipment (manometers, anemometers, ultrasonic flow meters, pressure/temperature calibrators, power analyzers, etc.), or demonstrated aptitude to learn it in the field.

- Familiarity with relevant codes and standards (ASHRAE, SMACNA, NFPA, ASME, IMC, LEED, Uptime Institute).

- Ability to read, interpret, and redline mechanical drawings, P&IDs, control schematics, and sequence of operations.

- Experience coordinating with multi-discipline teams, contractors, and vendors in construction environments.

- Ability to work safely in industrial construction environments and follow LOTO, NFPA, OSHA, and SpaceXAI safety protocols.

- Commissioning (Cx) experience, including functional performance testing, airflow/water flow verification, system balancing, integrated system testing, or system turnover.

- Data center cooling systems and prior work on hyperscale or mission-critical projects (100+ MW scale a plus).

- NEBB, AABC, or equivalent Certification in Testing, Adjusting, and Balancing (TAB).

- Hands-on experience with BMS/BAS controls troubleshooting and integration (BACnet, Modbus, LON, etc.).

- Knowledge of refrigerant systems, direct liquid cooling, and advanced heat rejection technologies.

- Current OSHA 30 certification (or equivalent).

- Proficiency with commissioning management platforms (CxPro, Procore, PlanGrid, or similar).

- Technical degree or trade school certification in Mechanical Engineering Technology, HVAC, or a related field.

- Experience implementing Integrated Systems Testing (IST) and Owner’s Project Requirements (OPR) verification.

## Additional Requirements:

- Willingness to travel extensively and work extended hours, nights, and weekends during critical commissioning and startup windows.

- Ability to travel extensively to SpaceXAI construction sites and remain onsite for extended periods during peak commissioning phases.

- Physical capability to work in industrial environments, climb ladders/stairs, lift moderate loads (up to 50 lbs), and wear full PPE for long durations.

- Valid driver’s license and ability to meet SpaceXAI's driver eligibility requirements.
