• 2+ years of professional experience in welding engineering, joining processes, or welded hardware manufacturing.
• Experience with common fusion welding processes (GTAW, GMAW, PAW, laser, EB).
• Experience developing or supporting welding procedures and welder qualifications.
• Understanding of welding metallurgy, heat-affected zones, distortion, residual stress, and common weld defects.
• Experience interpreting engineering drawings, weld symbols, material specifications, and inspection requirements.
• Familiarity with destructive testing and nondestructive examination methods used to evaluate weld quality.
• Ability to work hands-on with production personnel and independently resolve manufacturing challenges.

Responsibilities

• Develop, qualify, and maintain welding procedures, including WPS, PQR, and welder qualifications.
• Select appropriate welding processes, filler metals, joint designs, shielding methods, and process parameters.
• Provide design-for-welding guidance related to joint accessibility, distortion, residual stress, inspection, and manufacturability.
• Support welded hardware from prototype development through production, inspection, testing, and final acceptance.
• Collaborate with welders, technicians, and suppliers to establish repeatable, high-quality fabrication processes.
• Create manufacturing work instructions, process controls, weld maps, inspection criteria, and technical specifications.
• Develop and execute weld qualification plans, including destructive and nondestructive testing.
• Review weld documentation, inspection results, material certifications, and supplier records for compliance.
• Lead root-cause investigations for weld defects, distortion, cracking, leakage and other nonconformances.
• Develop repair and rework procedures and provide disposition of welding-related nonconformances.
• Interface with design, materials, analysis, manufacturing, quality, and test engineers to ensure assemblies meet requirements.
• Support qualification and oversight of welding suppliers and outside fabrication partners.
• Promote a culture of safety, quality, documentation, and continuous process improvement.
