About The Position

At General Motors, our product teams are redefining mobility. Through a human-centered design process, we create vehicles and experiences that are designed not just to be seen, but to be felt. We’re turning today’s impossible into tomorrow’s standard —from breakthrough hardware and battery systems to intuitive design, intelligent software, and next-generation safety and entertainment features. Every day, our products move millions of people as we aim to make driving safer, smarter, and more connected, shaping the future of transportation on a global scale. The Role This role supports the GM Energy and Propulsion Systems Research Lab in advancing propulsion and vehicle efficiency, reducing costs, and driving performance improvements. Warranty improvement and engineering development efficiency are also key areas of focus. As a member of this operations team, we are looking for a highly motivated individual that is technically skilled at developing and executing propulsion testing where tasks are unique and complex. Testing needs encompass the entire propulsion system from battery architecture, electric motor and inverter development, drive unit development, internal combustion engine development, and BEV/HEV/PHEV auxiliary systems. This is up to and including development of proof of concept demonstration vehicles.
