General Motors

General Motors relies heavily on computer-aided design (CAD), Class-A digital surfacing, and Product Lifecycle Management (PLM) to engineer its next-generation EV platforms (Ultium), autonomous vehicles (Cruise), and traditional truck and SUV lineups. CAD-related roles at GM span core product development and manufacturing teams, including body-in-white (BIW) structural design, electric propulsion and battery pack enclosures, central compute ECU hardware packaging, vehicle interior/exterior studio styling, and assembly plant automation tooling. Working in a CAD or mechanical design engineering role at GM involves using industry-standard tools like Siemens NX, Teamcenter, CATIA, and AutoCAD to execute parametric 3D modeling, perform virtual clearance/packaging studies, and apply strict GD&T across complex vehicle architectures.
