From the posting

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.

COMBO WELDER

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.
