> Welding Engineer responsible for qualifying WPS/PQR to AWS D1.1, inspecting/certifying welds, building weld quality programs, qualifying welders, and reducing defects for high-rate modular data center manufacturing. Requires current CWI credential and hands-on experience writing procedures and running quality programs in production environments.

## Job Description

## Role Scope
- 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.

## Requirements
- Current AWS Certified Welding Inspector (CWI) credential and have signed off on structural or pressure welds to AWS D1.1 or an equivalent code.
- Written and qualified WPS and PQR documentation for production welding, not just reviewed someone else's.
- Stood up or run a weld quality program in a manufacturing or fabrication environment producing at rate.
- Qualified welders and managed the continuity records that keep a line's certifications valid.
- 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.
- Read a weld map and a fabrication drawing and catch the problem before the first arc strikes.

## Nice-to-Haves
- 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.
