ABOUT THE ROLE

We are seeking a Certified Weld Inspector to support the buildout of SpaceXSI's high-performance data centers. In this hands-on role, you will inspect welds on industrial piping and structural steel and keep quality moving on our next-generation AI supercomputing infrastructure. You will work closely with welding, mechanical, structural, and operations teams to verify weld quality from construction through turnover. This is a full-time, onsite role with significant travel to SpaceXSI data center sites. This is an hourly position with overtime.

RESPONSIBILITIES

Inspect welds in progress and at completion on large-bore industrial piping and structural steel, and accept or reject them against the applicable code, welding procedure specification (WPS), and drawings. Interpret AWS, ASME, and project specifications against isometric, spool, structural, and arrangement drawings. Monitor GTAW, SMAW, FCAW, and GMAW work and confirm it is performed to the qualified welding procedure. Verify and document welder qualifications before a welder is released to weld on the package. Check joint design and preparation, fit-up, cleanliness, tack quality, preheat, interpass temperature, and interpass and final cleaning. Verify base metal and filler metal against the applicable specifications, including control and handling of welding consumables. Recommend and verify repairs, then visually inspect the completed repair before the joint is released. Oversee nondestructive examination and any required proof or mechanical testing, and confirm fabrication and inspection records are complete. Record inspection results and communicate findings to construction, welding, and engineering. Review contractor welding and inspection practices on site. Follow hot-work, LOTO, PPE, and site rules; report rejected welds, unsafe conditions, and drawing conflicts immediately. Support punch-list and NDE hold points through system turnover.
