• Design, develop, test, and deliver scalable, modular software solutions that address complex operational requirements across enterprise cloud and tactical edge environments within an open-architecture framework
• Translate functional and non-functional requirements, user stories, and acceptance criteria into well-structured, maintainable code that meets performance, security, and interoperability standards across multiple security domains
• Serve as a core technical contributor within agile development teams, collaborating with architects, integration SMEs, UX designers, and requirements analysts to ensure software solutions are accurately designed, developed, and verified throughout the program lifecycle
• Evaluate and validate software capabilities including data onboarding and normalization, API performance, credential authority, data logging and alerting, and end-to-end system behavior across multiple security domains and network environments
• Support development and validation of tactical edge software configurations, ensuring software solutions account for operations in DDIL environments including 72-hour autonomous operations and seamless data synchronization upon network restoration
• Participate in product demonstrations, design reviews, and agile development cycles, providing rapid software iteration and technical assessment of solution compliance against documented requirements and operational needs
• Collaborate with vendors, partners, systems analysts, and Government stakeholders to identify and resolve software defects, technical risks, and capability gaps throughout the program lifecycle
