Principal Software Engineer

About the Team: The Real-time Architectures, Integration, and Demonstration (RAID) Group focuses on transition of algorithms from concept to real-time software, providing open architecture expertise, and facilitating integration of capabilities for experimentation, test, and deployment. The Role: As a Principal Software Engineer you will provide technical leadership for the development, integration, and validation of real-time RF sensor software systems. You will work as part of a multi-disciplinary team to architect, guide, and implement software components, integrate algorithms into open architecture frameworks, and develop test infrastructure to validate system performance. This role emphasizes hands-on software development, open system integration, integrating software components across distributed architectures and with hardware platforms, and rigorous testing of real-time applications. You will establish integration and test approaches, identify and mitigate technical risks, mentor engineers, and collaborate with program leadership and government customers to ensure successful delivery of mission-critical capabilities. What you will do: Lead the technical design, development, integration, and validation of real-time sensor systems in C/C++ Integrate signal processing algorithms into open architecture software frameworks Define, develop, and execute integration tests and system-level validation tests Debug software issues in real-time, multi-threaded, and distributed systems Lead the transition of algorithm specifications and MATLAB/Python prototypes into optimized production C/C++ implementations Document software designs, test procedures, results, and technical reports as well as integration plans, technical briefings, and customer-facing presentations Support system demonstrations and field-testing activities Establish and promote best practices for software quality, configuration management, test automation, documentation, and technical risk management Mentor and provide technical guidance to junior and mid-level engineers Interface with government sponsors, customers, program managers, and technical stakeholders to define requirements, communicate technical status, and present results Lead or substantially contribute to proposal development, including technical approach development, work-breakdown planning, technical writing, cost estimation, white papers, and customer presentations Contribute to the design and implementation of user interfaces, dashboards, and visualization tools that support system observability, test execution, data analysis, and integration workflows Support approximately 10% travel for integration events, field testing, and customer demonstrations Who you are: Active clearance at the Secret level with ability to obtain and maintain a Top Secret security clearance, for which U.S. citizenship is a government requirement BS, MS, or PhD in Computer Science, Computer…
