Develop automotive exterior trim part models from early concepts through detailed design maturation. Create and refine A-surfaces and engineering surfaces while preserving design intent and downstream manufacturability. Define part geometry, interfaces, attachment features, locating schemes, and datum structures. Apply GD&T and support tolerance stack-up reviews to achieve fit, function, and assembly targets. Collaborate with DREs, styling, manufacturing, suppliers, quality, and tooling teams to resolve design issues. Apply DFM principles and incorporate feedback from toolmakers and manufacturing engineers. Support design reviews, prototype builds, tool reviews, part inspections, and engineering changes. Maintain accurate models, drawings, and product data in 3DEXPERIENCE (3DX). The position is located in Dearborn, Michigan, or Long Beach, California, and is a six-month contract.
