HMI Software Engineer - GM Defense

HMI Software Engineer

GM Defense is moving fast to deliver advanced mobility solutions for government markets. We are seeking a highly capable HMI Software Engineer to design, develop, and implement human-machine interface solutions for GM Defense products on the GM Defense Software and Controls Team. This position will support vehicle and non-vehicle applications across a diverse portfolio and work closely with the Design Studio and GMD program teams to create HMI systems that meet customer, product, and mission requirements.

Reporting to the Engineering Group Manager for the GM Defense Software and Controls Team, this role will be responsible for software development and integration of HMI solutions in a fast-paced, ambiguous environment. The selected candidate will translate evolving requirements into executable software designs, develop production-intent HMI applications, and support validation and issue resolution through launch and sustainment. This role is intended for a strong individual contributor who can operate independently, influence cross-functional decisions, and deliver high-quality software in a secure and highly regulated development environment.

What You'll Do

• Design, develop, and implement HMI software solutions for GM Defense vehicle and system applications
• Partner with the GM Design Studio and program teams to define and refine HMI concepts, workflows, and feature behavior
• Translate ambiguous customer, program, and engineering inputs into clear software requirements and implementation plans
• Develop HMI applications using Qt and related software frameworks in a Linux-based development environment
• Support software architecture, code implementation, debugging, and issue resolution for display and operator-interface features
• Participate in requirements development, peer reviews, software verification, and feature validation activities
• Execute software development in an Agile CI/CD environment using disciplined version control, build, and release practices
• Work cross-functionally with software, controls, systems, integration, validation, and cybersecurity teams to ensure robust end-to-end solutions
• Present technical status, design decisions, and issue-resolution plans to leadership and cross-functional teams as needed

Your Skills & Abilities (Required Qualifications)

• Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, Software Engineering or other technical discipline with relevant experience
• Experience in software development for embedded, application, or user-interface systems
• Experience developing software in Python, C++ or a similar object-oriented programming language
• Experience working in a Linux-based development environment
• Experience with Qt or similar HMI/application development frameworks
• Experience translating incomplete or ambiguous inputs into software requirements and executable technical solutions
• Experience working in an Agile CI/CD software development environment
• Strong analytical, communication, and interpersonal skills
• Ability to work effectively across design, engineering, and program teams without direct authority
• Candidate must be a U.S. Person (U.S. citizen, U.S. permanent resident, asylee or refugee).

What Will Give You A Competitive Edge (Preferred Qualifications)

• Experience in software engineering, HMI development, or embedded application development
• Experience designing and implementing operator displays, customer-facing software, or HMI workflows for complex systems
• Experience integrating HMI software with embedded controllers, vehicle communications, and diagnostics
• Familiarity with vehicle electrical architecture, communication protocols, and software integration processes
• Experience supporting software verification, validation, and issue resolution in fast-paced development environments
• Experience operating in classified, export-controlled, or highly restricted development environments
• Knowledge of GM vehicle development, build, and launch processes
• Ability to obtain DoD Secret clearance
