About The Position

Intelligence operations depend on fast, reliable access to geospatial data that supports real-world decision-making. In these environments, the systems delivering that data must remain intuitive, responsive, and dependable at all times. As a Front-End Engineer supporting the Marine Corps Intelligence Activity (MCIA), you will contribute to a mission-critical geospatial intelligence platform used across the Department of Defense and Intelligence Community. This system serves as a primary interface between intelligence data and the analysts who rely on it to support time-sensitive operational decisions. The Geospatial Support Services (GSS) portal plays a direct role in how intelligence is accessed, understood, and applied in operational contexts. Improvements to usability, performance, and accessibility directly impact how quickly and effectively mission partners can act on geospatial intelligence. In this role, you will be building responsive UI components for a production intelligence system.
