Combo Welder - Memphis

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 Welder to support the buildout of SpaceXSI's high-performance data centers. In this hands-on role, you will fit and weld large industrial piping and structural steel to ASME Section IX and keep construction moving on our next-generation AI supercomputing infrastructure. You will work closely with mechanical, structural, electrical, and operations teams to weld pipe, supports, and structures from construction through turnover. This is a full-time, onsite role with significant travel to SpaceXSI data center sites. RESPONSIBILITIES: Fit, tack, and weld large-bore industrial piping and/or structural steel (pipe racks, platforms, supports, skids, and related assemblies) per drawings and ASME Section IX welding procedure specifications (WPS). Lay out, cut, bevel, grind, and align joints; check fit-up, root opening, and reinforcement before and after the weld. Read isometric, spool, and structural drawings; work to weld maps, heat numbers, and rod-control / continuity requirements where used. Support hanging of strut, supports, hangers, and structural members; assist with equipment set and bolt-up as needed to complete the weld package. Stage, move, and inventory pipe, fittings, structural members, filler metal, and tools; keep laydown yards and work areas orderly. Open and close work areas: protection, fire watch and hot-work permits, debris removal, scrap segregation, and end-of-shift reset so the next crew can start immediately. Follow LOTO, PPE, hot-work, and site rules; do not weld on live or unpurged systems without authorization. Report damaged material, rejected welds, unsafe conditions, and drawing conflicts immediately. Support punch-list, repair, and NDE hold-point work through system turnover. BASIC QUALIFICATIONS: Journey-level industrial construction welding experience: 3+ years welding large industrial piping and/or structural steel, completion of a recognized welding apprenticeship, or equivalent military experience. PREFERRED SKILLS AND EXPERIENCE: Hands-on experience with GTAW (TIG) on stainless steel and/or SMAW (stick) on carbon steel. Qualified to ASME Section IX, or ability to pass a pre-employment weld test to ASME Section IX in the process(es) and position(s) used on site. Willingness to work at heights, outdoors, and on a changing data center construction site. Ability to use welding machines, torches, grinders, and related hand and power tools safely. Strong safety mindset and willingness to follow site procedures, including hot-work permits and LOTO. Prior experience on data center, industrial, or heavy-civil construction sites. Experience welding large-bore process, mechanical, or utility piping and heavy structural members. Current ASME Section IX qualification (e.g. 6G) in GTAW on stainless and/or SMAW on carbon. Proficiency in both TIG-on-stainless and stick-on-carbon; FCAW a plus. AWS D1.1 structural welding qualification or equivalent. OSHA 10 or equivalent training. Ability to read isometric, spool, and structural drawings. 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 (including welding PPE) for extended periods, with or without reasonable accommodation. SpaceXSI is an equal opportunity employer. For details on data processing, view our Recruitment Privacy Notice .
