Pre Commissioning information

What is a pre commissioning?

A Pre Commissioning job involves preparing systems and equipment for initial startup in industries like oil and gas, power plants, and manufacturing. It includes inspections, testing, flushing, and verifying that all components meet design specifications before full commissioning. This phase ensures safety, reliability, and compliance with engineering standards. Pre Commissioning typically occurs after construction but before full operational testing. It helps identify and resolve potential issues early, reducing risks during final commissioning and startup.

What are some typical challenges faced in a pre commissioning role and how can they be managed?

Pre Commissioning professionals often encounter challenges such as tight project timelines, unforeseen equipment issues, and coordination with multiple stakeholders. Managing these challenges requires strong organizational skills, quick problem-solving, and maintaining clear communication channels among engineering, construction, and client teams. Proactively conducting thorough inspections and adhering to established protocols can help mitigate risks and minimize downtime. Staying adaptable and keeping up with the latest industry standards also enhances efficiency and safety in the role.

What are the key skills and qualifications needed to thrive in the pre commissioning position, and why are they important?

To thrive in a Pre Commissioning role, you need a strong understanding of engineering principles, site safety practices, and equipment testing protocols, typically supported by a degree in engineering or a technical diploma and relevant industry experience. Familiarity with pre-commissioning checklists, pressure testing equipment, flushing systems, and industry standards such as API or ASME codes is important, and certifications like OSHA or CompEx may be required. Excellent problem-solving abilities, attention to detail, and effective communication skills are crucial for coordinating with project teams and addressing issues efficiently. These competencies ensure systems are safely and thoroughly prepared for initial operation, enhancing project success and client satisfaction.

Is pre commissioning a good career?

Pre commissioning is a vital phase in project execution, involving testing and verifying systems before full operation. It offers opportunities in industries like oil and gas, power, and manufacturing, often requiring technical skills, certifications, and attention to detail. The career can be stable and rewarding for those interested in project management and technical troubleshooting.

Job description

SpaceXAI's mission is to create AI systems that can accurately understand the universe and aid humanity in its pursuit of knowledge. Our team is small, highly motivated, and focused on engineering excellence. This organization is for individuals who appreciate challenging themselves and thrive on curiosity. We operate with a flat organizational structure. All employees are expected to be hands-on and to contribute directly to the company's mission. Leadership is given to those who show initiative and consistently deliver excellence. Work ethic and strong prioritization skills are important. All employees are expected to have strong communication skills. They should be able to concisely and accurately share knowledge with their teammates.

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 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 SpaceXAI data center 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 center 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 SpaceXAI 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 centers, power plants, or large industrial facilities.
  • Strong working knowledge of data center 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 center 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.
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.
