Key responsibilities:

• Develop BIW concepts using structural castings, steel and aluminum stampings, extrusions, roll forms, composites, and hybrid assemblies.

• Lead casting reviews covering alloy, wall thickness, ribs, draft, parting lines, gating, porosity, distortion, machining, tooling, and datum strategy.

• Identify opportunities for part consolidation, joint reduction, attachment integration, mass reduction, and assembly simplification.

• Review structural sections, load paths, crash management, stiffness, fatigue, durability, and local attachment requirements with CAE teams.

• Develop mixed-material strategies using FDS, resistance/MIG/laser welding, FSW, SPR, bolts, mechanical fasteners, adhesives, and sealers.

• Evaluate joints for material stack, access, loading, fatigue, corrosion, sealing, heat input, distortion, cycle time, equipment, and repairability.

• Define flange, access, edge-distance, adhesive, surface-treatment, sealing, and corrosion requirements; support coupon and subsystem validation.

• Assess suppliers, simulations, tooling, process controls, machining, inspection, quality plans, prototype trials, and casting/joining root causes.

• Bachelor's degree in Mechanical, Materials, Metallurgical, Manufacturing, Welding Engineering, or a related field.

• +3 years of automotive BIW, structural, casting, materials, or joining experience.

• Demonstrated structural casting expertise, preferably aluminum HPDC, plus experience with two additional BIW processes.

• Strong knowledge of mixed-material joining, metallurgy, corrosion, fatigue, dimensional control, GD&T, DFMEA, DVP&R, PFMEA, and joint validation.
