Job Description About xAI

xAI'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.

You will oversee mechanical contractors and crews building the advanced mechanical infrastructure for xAI's Data Centers — including large‑scale HVAC and cooling systems, chilled water plants, condenser water systems, process piping, pumps, CRAC/CRAH units, cooling towers, and fire protection systems. If you thrive on hands‑on leadership, complex industrial mechanical construction, and contributing to high‑impact AI infrastructure, join us to help deliver one of the most advanced and efficient data centers in the world.

This is a full‑time, onsite role based in Memphis, Tennessee, with relocation required depending on additional construction locations within the US.

• Oversee and coordinate mechanical installations including chilled water piping, condenser systems, HVAC equipment, cooling towers, pumps, heat exchangers, ductwork, CRAC/CRAH units, and fire suppression systems for xAI Data Centers.
• Manage and schedule mechanical contractors, subcontractors, and on‑site crews to deliver project milestones on time and to xAI's exacting quality and reliability standards.
• Ensure all contractors adhere to mechanical scope, delivering high‑integrity cooling and process systems critical to data center uptime, efficiency, and thermal management.
• Monitor daily progress of mechanical construction, maintaining detailed logs, red‑line drawings, and as‑built documentation for all mechanical infrastructure.
• Develop and enforce aggressive construction schedules while keeping the project on time and within budget.
• Champion and enforce xAI's safety program, building a zero‑incident culture across all teams working around heavy mechanical equipment, pressurized systems, and elevated work.
• Supervise foremen and mechanical crews, fostering teamwork and accountability in a high‑stakes mission‑critical environment.
• Proactively resolve on‑site challenges — material delays, technical conflicts, sequencing issues, and coordination with electrical/civil trades — with a strong focus on mechanical system reliability and code compliance.
• Conduct regular site inspections to verify compliance with local regulations, mechanical codes, safety protocols, and xAI's stringent quality standards.
• Prepare and present clear progress reports, mechanical construction metrics, and risk updates to senior leadership.

• 3+ years managing mechanical construction teams with strong emphasis on large‑scale industrial or mission‑critical mechanical projects.
• 3+ years of direct hands‑on experience in mechanical installations including process piping, HVAC systems, chilled water plants, pumps, and cooling infrastructure — ideally on data centers, industrial processes, or heavy mechanical projects.
• High school diploma or equivalency certificate.

• Postsecondary diploma or degree in construction management, mechanical engineering, or related field.
• Proven track record supervising mechanical construction for data centers, hyperscale facilities, or similar mission‑critical environments.
• Familiarity with Memphis‑area building codes, mechanical regulations (IMC, ASME, NFPA), and industrial permitting.
• Experience with construction management software (Procore, AutoCAD, Bluebeam, MS Project, etc.) on complex infrastructure projects.
• Deep knowledge of mechanical construction critical paths, sequencing, and coordination with electrical/civil trades…
