Senior Software Engineer - HIL Battery & Propulsion Simulation & Integration

Hybrid: This role is categorized as hybrid. This means the successful candidate is expected to report to Milford, Michigan 3-4 days per week, at minimum [or other frequency dictated by the business if more than 3 days]. Overview General Motors is undergoing a major transformation, both in how we operate and in how we will influence the future of transportation in the EV realm. Our Software Services team is on the forefront of this work, seeking determined, innovative individuals who will help move us forward and achieve our mission. Role The Battery & Propulsion HIL Engineer is responsible for creating hardware‑in‑the‑loop (HIL) environments to enable development, verification, and validation of embedded controllers and calibrations for battery, electrification, engine, and powertrain. This includes designing and maintaining models using dSpace Simulink and Simscape tools, designing the harness, layout, the ECUs, and power for our HIL bench, and delivering finished products on time. What You’ll Do Work closely with software development, calibration, validation, and test‑environment users to translate customer needs into testable system requirements and solutions. Create and maintain simulation models (e.g., plant, sensors and actuators, serial data communication, controller models) to build and enhance HIL/SIL test environments. Design, integrate, and support HIL benches, including harness design, power distribution, integration of key ECMs, and use of ISO SPI, CAN tools, and INCA. Plan, communicate, and coordinate test‑environment strategy and model/hardware rollout to support applications and features requested by the user community. Partner with test‑environment users to investigate, root cause, and resolve issues and unexpected test results during test execution. Lead systems engineering activities, including requirements specification and balancing, functional decomposition, complex design analysis, and software anomaly resolution for current, new, and major programs. Provide, communicate, and champion common best practices within the software community; perform as Subject Matter Expert (SME) for at least one platform or application component. Apply Agile principles, DFSS tools and methodologies, and Lean thinking to continuously improve HIL engineering processes and daily work. Work with sources of models and equipment to ensure common models and other simulation assets are shared and reused across test‑environment domains and architectures. Required Qualifications Master’s degree in engineering (Mechatronics, Electrical, Software or Computer preferred). Bachelor’s degree in engineering (Mechatronics, Electrical, Software or Computer). 4+ years of experience in design of models with real‑time simulation. 4+ years of experience in HIL design, troubleshooting and integration. 2+ years of experience in automotive engineering. 1+ year of experience in applying DFSS tools and methodologies to solve problems. Preferred Qualifications Experience with developing microprocessor‑based, real‑time control algorithms and software in high‑level (Python, C/C++) language. Experience with embedded controls software and the automated software build processes, including gcc compiler, gdb debugger, Eclipse, and ETAS INCA measurement and calibration tools. Experience with commonly used HIL bench tools, such as ETAS INCA, Lauterbach, CAN (CANalyzer or Vehicle Spy), software code generation, Python, etc. Experience as a Controls, Software, or Calibration Engineer. Relocation & Immigration This job may be eligible for relocation benefits. GM DOES NOT PROVIDE IMMIGRATION‑RELATED SPONSORSHIP FOR THIS ROLE. DO NOT APPLY FOR THIS ROLE IF YOU WILL NEED GM IMMIGRATION SPONSORSHIP (e.g., H‑1B, TN, STEM OPT, etc.) NOW OR IN THE FUTURE.
