Today, SpaceX is actively developing the technologies to make this possible, with the ultimate goal of making life multiplanetary and expanding consciousness to the stars.\nSpaceXSI is building Super Intelligence to help humanity understand the universe. Our teams are building the full Super Intelligence stack: from our Colossus supercomputers, to Grok models, to our suite of applications, including Grok Bot, Grok Build, Grok Imagine, Grok Voice, and X. We're creating a powerful flywheel where more compute trains better models, better models power more useful products, and what we learn from people using those products shapes what we build next.\nCONSTRUCTION SUPERINTENDENT, FLUID/MECHANICAL\nMost construction jobs manage someone else’s crew on someone else’s schedule, then end when the project does. This one does not.\nSpaceX builds its own launch sites, factories, test stands, and AI superclusters - and it plans to keep building. The rockets, the chips, and the missions only matter if the ground under them is real. Construction is how that ground gets built, in-house and to a standard the company can actually use. The work does not dry up between jobs. There is a next site, and one after that. You lead the crew that builds them.\nYou own a self-performing team. Foremen run their people day to day. You run the foremen. You are in the dirt, walking the work, setting the bar, and clearing whatever is in the way. When someone is ready for more, you say so. When the standard slips, you deal with it.\nScope includes, but not limited to industrial HVAC, pipefitting, pipe welding, chilled water, cooling towers, chillers, condensers, CRAC and CRAH units, and setting that heavy mechanical equipment. It also includes all plumbing: domestic water, sanitary, drain-waste-vent, and floor drains. It includes all fire protection: sprinkler fitting, suppression, and pre-action. This is the work that moves heat, water, and fire protection through the building.\nThe team goes where the next site is - a pad, a factory, a supercluster, whatever has to exist before the rest of the company can move. Right now that is Memphis, TN / Southaven, MS. Then it is the next one. Per diem comes with the assignment.\nRESPONSIBILITIES:\nDirectly oversee foremen and, through them, a large self-perform fluid/mechanical crew installing industrial HVAC, pipe, chilled water, cooling towers, chillers, condensers, CRAC and CRAH units, plumbing, and fire protection, including pipe welding and setting heavy mechanical equipment\nSet clear expectations for safety, quality, schedule, and conduct, and hold foremen and crews accountable when those expectations are missed\nRemove roadblocks so crews can keep working: materials, access, sequencing, coordination with other trades, and decisions\nRecommend promotions, role changes, and corrective action based on performance\nPlan and run the night-shift assignment, including extended hours, as part of a 24/7 operation\nKeep fluid and mechanical installations on SpaceXSI’s quality and reliability standards, including code compliance and system integrity required for data center cooling and fire protection\nTrack daily progress and maintain logs, red-line drawings, and as-built documentation for mechanical, plumbing, and fire-protection systems\nBuild and hold an aggressive construction schedule, on time and within budget\nChampion SpaceXSI’s safety program and a zero-incident culture around pressure piping, hot work, rigging and setting heavy mechanical equipment, and work at heights\nResolve on-site issues - material delays, technical conflicts, sequencing, and trade coordination - with attention to system integrity and code compliance\nInspect work for compliance with local regulations, mechanical, plumbing, and fire-protection codes, safety protocols, and SpaceXSI quality standards\nReport progress, fluid/mechanical construction metrics, and risks to senior leadership\nRelocate with the mobile team as assignments change, starting in Memphis, TN / Southaven, MS\nBASIC QUALIFICATIONS:\nHigh school diploma or equivalency certificate\n3+ years leading fluid/mechanical construction teams, including supervision of foremen\n3+ years of direct hands-on experience in fluid/mechanical installations, including industrial HVAC, pipefitting, chilled water, plumbing, or fire protection\nPREFERRED SKILLS AND EXPERIENCE:\nExperience leading large self-perform crews on industrial or mission-critical mechanical, piping, or fire-protection projects\nDirect hands-on experience on industrial processes or heavy mechanical projects\nPostsecondary diploma or degree in construction management, mechanical engineering, or a related field\nTrack record on data centers, hyperscale facilities, or similar mission-critical mechanical construction\nFamiliarity with Memphis-area building codes, IMC, IPC, NFPA 13, and industrial permitting\nExperience with Procore, AutoCAD, Bluebeam, MS Project, or similar tools on complex infrastructure work\nStrong grasp of mechanical critical path, sequencing, and coordination with electrical, structural, and civil trades through commissioning\nUnderstanding of data center cooling and fire-protection requirements, including chilled water, cooling towers, CRAC and CRAH units, and systems built for 24/7 operation\nHistory of leading diverse crews to a deadline without giving up collaboration or safety\nWorking knowledge of lockout/tagout, hot work, pressure testing, and a record of building a safety culture on regulated sites\nStrong problem-solving and conflict resolution on technically complex mechanical, plumbing, and fire-protection work\nProficiency with Microsoft Office (Excel, PowerPoint, Word, Teams, Project)\nADDITIONAL REQUIREMENTS:\nSubject to pre-employment drug screening and random drug/alcohol testing, and pre-employment/post-employment background checks\nThis role is part of the mobile construction team and you will be expected to travel to the assigned work project. Current work assignment is based in Memphis, TN / Southaven, MS. Future assignments will require relocation to other U.S. construction sites. Per diem is provided while on assignment\nMust be willing to work any shift, extended hours and/or holidays during assigned work assignment. This includes rotating shifts, nights and/or weekends. If you are assigned night shift, you will receive a shift differential for hours worked during off nominal hours\nMust be willing to work in industrial environments with exposure to noise, heavy equipment, excavations, and energized electrical systems. Must be able to lift 25 lbs or more and perform physically demanding tasks outdoors, indoors, in tight conditions, and/or at heights, with or without reasonable accommodation\nSpaceXSI is an equal opportunity employer.
