About The Position

Parsons is looking for a talented Lead Software Engineer to provide technical and program leadership to our growing team supporting a high-priority national security mission. In this role, you will lead the architecture, design, development, and integration of an advanced Signals Intelligence (SIGINT) data fusion and analytics platform, working closely with the Program Manager and customer to establish requirements, technical priorities, and program execution strategy. The platform integrates multiple intelligence data sources into a unified operational environment, leveraging modern data processing technologies, APIs, advanced data correlation and entity resolution, and advanced visualization capabilities to support intelligence analysis, vulnerability research, and collaborative mission planning. This position offers an opportunity to provide program-level technical leadership on cutting-edge intelligence integration projects, establishing technical direction and guiding the development of secure, scalable, and high-performance solutions that support critical national security missions. This position will offer a hybrid work schedule.
