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
