Software and Controls Engineer – GM Defense

Job Description The Role

GM Defense is moving fast to deliver advanced mobility solutions for government markets. We are seeking a highly capable Software & Controls Engineer to design, develop, and implement custom embedded control algorithms. This position will support both vehicle and non-vehicle applications across our unique portfolio.

Reporting to the EGM of Electrical Systems, Controls, and Software (ESCS) team, you will be hands‑on in writing code and integrating requirements specific to GM Defense platforms. This is a fast‑paced role where you will operate with independence to impact compressed‑timeline programs—such as developing in‑house controls solutions (like custom Vehicle Interface Modules) and optimizing system performance across complex electrical architectures.

• Serve as a key technical contributor for the design, development, and implementation of embedded control systems for our unique customer base.
• Resolve complex technical issues in an ambiguous, fast-moving, start‑up‑style environment.
• Operate with independence and sound judgment to drive results on critical programs.
• Collaborate cross‑functionally to implement custom solutions while balancing GM best practices with strict government specifications.

• Design and test controls using C hand code, MATLAB, & Simulink tools for both vehicle and non‑vehicle applications.
• Work collaboratively with systems integration engineers and technical leads to implement control algorithms for propulsion, chassis, and other complex systems into existing or new supervisory controls.
• Describe and report on algorithm design choices and function when required.
• Support calibration of controls to optimize performance.
• Collaborate with embedded controls teams from the greater GM organizations to implement requirements that are unique to GM Defense customers.
• Support software verification and feature validation as needed.
• Work to achieve compliance and balance between GM Best Practices and government specifications.
• Participate in electrical design/peer reviews and present updates to cross‑functional program integration teams and leadership as needed.
• Stay abreast of the latest simulation and controls methods.

GM does not provide immigration‑related sponsorship for this role. Do not apply for this role if you will need GM immigration sponsorship now or in the future. This includes direct company sponsorship, entry of GM as the immigration employer of record on a government form, and any work authorization requiring a written submission or other immigration support from the company (e.g., H1-B, OPT, STEM OPT, CPT, TN, J‑1, etc).

This role is categorized as hybrid. This means the selected candidate is expected to report to a specific location at least 3 times a week {or other frequency dictated by their manager}.

• BS in Electrical Engineering, Mechanical Engineering, Aerospace Engineering, Computer Science or Computer Engineering.
• Embedded controls experience (algorithm, software or calibration).
• 2+ years’ experience in C programming, MATLAB, and Simulink algorithm development.
• Experience with development and test tools such as INCA and Vehicle Spy (VSpy), as well as software build tools (Git/Jenkins).
• Must be familiar with GM data logging tools and file formats.
• Ability to legally operate a motor vehicle.
• This position requires either a U.S. Person (as defined in applicable export regulations) or a non‑U.S. Person who is eligible to obtain required export authorization(s).

• Master’s degree in an Engineering discipline.
• Experience with Agile CI/CD workflow.
• Familiarity with GM’s VIP electrical architecture.
• GM Level 2…
