SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. 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. SpaceXSI 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. ABOUT THE ROLE: We are seeking an Industrial Pipefitter to support the buildout of SpaceXSI's high-performance data centers. In this hands-on role, you will install large industrial piping systems and keep construction moving on our next-generation AI supercomputing infrastructure. You will work closely with mechanical, welding, structural, electrical, and operations teams to fit, hang, and test pipe from construction through turnover. This is a full-time, onsite role with significant travel to SpaceXSI data center sites. RESPONSIBILITIES: - Install large-bore industrial piping (process, mechanical, utility, and related systems): measure, cut, bevel, fit, hang, and make up joints per drawings and specs. - Perform flange, groove, thread, and welded-joint fit-up; align pipe, set gaps, and prep joints for the welding crew. - Install valves, fittings, hangers, supports, strut, and anchors; hang pipe racks and supports plumb and on grade. - Read isometric, spool, and arrangement drawings; field-route as directed and flag drawing conflicts before install. - Support hydro, pneumatic, and service tests: install blinds and test packs, walk lines, and repair leaks. - Stage, move, and inventory pipe, valves, hangers, insulation, tools, and equipment; keep laydown yards and mechanical rooms orderly. - Assist with equipment set for pumps, cooling towers, air handlers, and related mechanical gear, including bolt-up of suction and discharge piping. - Open and close work areas: protection, debris removal, scrap segregation, and end-of-shift reset so the next crew can start immediately. - Follow LOTO, PPE, and permit rules; do not work on live systems without authorization. - Report damaged material, unsafe conditions, and drawing conflicts immediately. - Support punch-list work and cleanup through system turnover. BASIC QUALIFICATIONS: - 3+ years installing large industrial or commercial piping OR completion of a recognized pipefitter apprenticeship, OR equivalent military experience. PREFERRED SKILLS AND EXPERIENCE: - Experience fitting and installing welded, flanged, grooved, and/or threaded pipe, including hangers and supports. - Willingness to work at heights, outdoors, and on a changing data center construction site. - Ability to use pipefitting hand tools, power tools, bevelers, and material-handling equipment safely. - Strong safety mindset and willingness to follow site procedures, including LOTO and permits. - Willingness to work extended hours, nights, and weekends during critical construction windows. - Prior experience on data center, industrial, or heavy-civil construction sites. - Experience on large-bore welded industrial piping (carbon and/or stainless) and equipment connections (pumps, air handlers, cooling towers, skids). - Ability to read isometric, spool, and P&ID drawings. - UA, NCCER, or equivalent pipefitter credential. - OSHA 10 or equivalent training. - Familiarity with hot-work, hydrotest, and flange-management practices. - High school diploma or equivalency certificate. ADDITIONAL REQUIREMENTS: - Ability to travel extensively to SpaceXSI data center construction sites and remain onsite during peak construction phases. - Capability to work in industrial environments, climb ladders, lift and position moderate loads, stand and walk for a full shift, and wear PPE for extended periods, with or without reasonable accommodation.
