Welding Engineer / AWS D1.1 CWI at Fluidstack (Austin, TX)Welding Engineer / AWS D1.1 CWI

We exist to make humanity more free. For most of human history, you farmed or you starved. Technology gave people more time for the things they wanted to do, instead of things they had to do. Powerful AI will be the biggest lever for human choice we've ever built - but only if models are aligned with what humanity actually wants. There are groups building AI who don't share these goals. Whoever deploys frontier compute infrastructure fastest will decide whether AI expands human freedom or shrinks it.

We're singularly focused on delivering 10 to 100s of GWs of compute faster than anyone else, rethinking every layer of the stack. We acquire power, design and build data centers, and operate them - with teams spanning hardware and software. Speed and scale are our key differentiators. Come be a part of building civilization-scale infrastructure for AI.

We hire people who care deeply about this problem space. If that is you, please apply!

• Be a barrel. Full autonomy. Own things end to end, take on scope without being asked, no permission required to operate outside your core role.
• Insane urgency. We drive everything forward as fast as possible.
• Reason from first principles. Challenge every assumption. Zero analogy thinking, no egos, the best idea wins.
• Love of the game. The frontier of AI is the most interesting problem of our time. We put in long hours at high intensity to push the frontier forward.
• Build something that actually matters. If you're going to spend your time, spend it on something that matters to the world.

• Write and qualify welding procedure specifications and procedure qualification records to AWS D1.1 for the structural and pressure-boundary welds in modular data center assemblies.
• Inspect and certify welds across the manufacturing line, signing off on the work an AHJ or auditor will not accept without a qualified inspector.
• Build the weld quality program for a factory producing data center modules at rate, setting the acceptance criteria, NDE requirements, and first-pass-yield targets.
• Qualify welders and welding operators, and stand up the continuity and requalification tracking that keeps the whole line certified.
• Drive down weld defect and rework rates by root-causing failures on the floor and feeding fixes back into procedures and fixturing.

• The below is a starting point. We always make space for exceptional people, so if you don't fit this role exactly, tell us where you would jobs.ashbyhq.com
• You hold a current AWS Certified Welding Inspector (CWI) credential and have signed off on structural or pressure welds to AWS D1.1 or an equivalent code.
• You've written and qualified WPS and PQR documentation for production welding, not just reviewed someone else's.
• You've stood up or run a weld quality program in a manufacturing or fabrication environment producing at rate.
• You've qualified welders and managed the continuity records that keep a line's certifications valid.
• You root-cause weld defects on the floor and close the loop by fixing the procedure, the fixture, or the training, so the same defect doesn't come back.
• You read a weld map and a fabrication drawing and catch the problem before the first arc strikes.
• Bonus: ASME Section IX or B31 piping. NDE certifications (UT, RT, MT, PT). High-volume or modular fabrication. Robotic or automated welding. Data center or mission-critical infrastructure fabrication.
