GENERAL PURPOSE The Senior Prototype Fabricator will independently build, modify, and coordinate the fabrication of prototypes, models, mock-ups, and development assemblies to support product design, engineering evaluation, testing, and presentation requirements. You’ll work from sketches, engineering drawings, and 3D CAD models to fabricate high-quality prototype components and assemblies while meeting project schedules and development objectives. Serve as a technical expert in prototype fabrication, sheet metal forming, welding, machining, and assembly processes. Collaborate closely with Design and Development teams to determine the most effective fabrication methods and provide feedback regarding manufacturability and prototype feasibility.

ESSENTIAL FUNCTIONS • Independently fabricate prototype parts, assemblies, mock-ups, and test fixtures from engineering drawings, CAD models, sketches, and design concepts.

• Set up and operate fabrication equipment including press brakes, welders, mills, lathes, drill presses, and other model shop equipment.

• Perform sheet metal layout, forming, bending, fitting, cutting, finishing, and assembly operations.

• Perform MIG, TIG, spot welding, and other joining processes as required.

• Determine fabrication sequences, tooling requirements, and manufacturing methods with minimal supervision.

• Design and build fixtures, tooling, jigs, and fabrication aids to support prototype development.

• Collaborate with engineering and design teams to recommend practical fabrication solutions and manufacturability improvements.

• Lead cost estimating exercises for components and large development builds.

• Inspect fabricated parts and assemblies to verify dimensional and functional requirements.

• Troubleshoot prototype issues and implement timely corrective actions.

• Mentor and train apprentice and junior model makers.

• Take strong ownership of projects and provide feedback to customers and engineering teams on fabrication methods, challenges, and improvements.

• Maintain a safe, organized, and efficient work environment.

• Perform additional responsibilities as requested to achieve business objectives.
