Senior Virtual Hardware Model Engineer

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 advancement of virtual tools has improved the way hardware and software can be optimized in vehicle design. As a Senior Virtual Hardware Model Engineer, you have the unique opportunity to shape GM's future by partnering cross functionally to develop models that unlock our ability to optimize design parameters within hardware components. In this role, you will lead development of select models in collaboration with suppliers, product development engineers, and other systems, software, and virtual teams. What You’ll Do (Responsibilities) Develop high-fidelity component plant models in MATLAB/Simulink that mathematically emulate the electrical, mechanical/physics, and software interfaces of GVHE hardware components. Collaborate cross-functionally (Tech Specialists, DREs, VDDV, SIL, CoSim, suppliers) to understand hardware designs, control strategies, and boundary conditions, and translate them into clear modeling requirements. Implement plant models in a form suitable for use in GM CoSim environments (e.g., FMU export), ensuring correct I/O definitions, signal naming, and execution behavior. Use supplier specifications, design data, and physical test/bench/vehicle results to parameterize, correlate, and continuously improve model fidelity. Support integration of component plant models into larger system and vehicle-level co-simulation environments, working closely with simulation integration and CoSim architecture teams. Leverage plant models as virtual harness/component testers to confirm performance, run what-if studies, and explore fault and edge-case behavior before hardware is available. Document modeling assumptions, limitations, calibration parameters, and validation results to enable reuse and traceability across programs. Lead development and maintenance of model requirements documentation (Appendix C11, C12), with technical leadership in developing component plant model requirements, test needs, and deliverables are clearly specified and up to date. Contribute to standard methods, libraries, and best practices for component plant modeling within GVHE, mentoring peers and helping scale the capability across programs Own system-level modeling strategy across multiple components/domains (e.g., closures, thermal, chassis), including how component plant models roll up into integration/system models. Define and drive standards and best practices for model architecture, naming, fidelity levels, correlation methods, and validation criteria across programs. Lead model correlation and validation strategy: decide which tests/data are needed, set acceptance thresholds, and arbitrate trade-offs between fidelity and runtime. Your Skills and Abilities (Required Qualifications) Bachelor’s degree in Engineering, Math, Physics, Computer Science, or other relevant degree Minimum 5 years of experience in product development, systems engineering, or work related to software/hardware connectivity. Preferred experience in translating physical phenomena into mathematical/Simulink models (electrical, mechanical, and software I/O). Proficiency with Matlab/Simulink or similar software that uses code-based logic for model-based simulation. Track record of delivering complex multi-domain models (coupled electrical–mechanical–software behavior) into SIL/HIL/CoSim workflows. Strong communication and collaboration skills Skilled and proficient with
