• 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
