The Fabrication Supervisor – Prototype & Engineering Builds leads the day-to-day execution of prototype, First-of-Kind (FOK), engineering validation, and pre-production builds.

This is a hands-on, shop-floor leadership role supervising welders, fabricators, fitters, assemblers, and other skilled-trades personnel. You will translate build priorities into daily execution, monitor quality and progress, and work closely with Engineering and Quality to resolve issues before they impact the build.

• Lead daily prototype, FOK, validation, and pre-production fabrication activities.
• Assign and coordinate work across welders, fabricators, fitters, assemblers, and other skilled trades.
• Monitor build progress, labor utilization, workmanship, rework, constraints, and schedule risks.
• Provide hands-on leadership, coaching, feedback, and accountability to shop-floor personnel.
• Oversee welding, fitting, fabrication, metalworking, assembly, and related build activities.
• Ensure work is completed to approved drawings, specifications, weld requirements, tolerances, and acceptance criteria.
• Review fit-up, alignment, dimensional condition, weld preparation, distortion, assembly quality, and overall workmanship.
• Ensure teams are working from the latest approved drawings, redlines, BOMs, and authorized instructions.
• Identify fabrication, material, tooling, documentation, quality, and design issues early and engage the appropriate Engineering or Quality owner.
• Stop and escalate work when requirements are unclear, conflicting, incomplete, or impractical rather than allowing undocumented workarounds.
• Enforce safety requirements including PPE, hot work, LOTO, machine guarding, lifting, material handling, and housekeeping.
• Partner with Design Engineering, Welding Engineering, Manufacturing Engineering, and Quality to improve manufacturability, fit, tooling, assembly sequence, and production readiness.
• Support 5S, visual management, tool control, and continuous improvement within the engineering-build environment.

• High school diploma or equivalent.
• 7+ years of progressive experience in welding, fabrication, metalworking, industrial assembly, prototype fabrication, or a related manufacturing environment.
• 3+ years of lead, foreman, or supervisory experience overseeing welders, fabricators, fitters, assemblers, or other skilled-trades personnel.
• Strong practical knowledge of welding and metal-fabrication processes.
• Ability to read and interpret engineering and fabrication drawings, dimensions, tolerances, weld symbols, and specifications.
• Experience coordinating labor assignments, shop priorities, and multiple active work fronts.
• Ability to recognize when an issue is related to workmanship versus design, documentation, material, tooling, or engineering.
• Strong commitment to safety, quality, accountability, and disciplined execution.
• Clear communication skills with the ability to communicate priorities, build status, risks, and technical concerns.
• Ability to perform the essential functions of the position with or without reasonable accommodation.

• Trade-school credential, apprenticeship, welding certification, or other relevant technical training.
• Experience supporting prototype, First-of-Kind, engineering validation, or low-volume/pre-production builds.
• Experience with large welded structures, fabricated enclosures, skids, modular equipment, or similar products.
• Experience working closely with Design Engineering, Welding Engineering, Manufacturing Engineering, and Quality.
• Familiarity with weld procedures, dimensional inspection, nonconformance processes, rework controls, and engineering change control.
• Experience with 5S, visual management, continuous improvement, and shop-floor organization.
