## Description

This role supports analysts and mission partners within the Marine Corps Intelligence Activity (MCIA) and across the broader Department of Defense (DoD) and Intelligence Community (IC) by building web-based interfaces used to access and visualize complex data. The applications you develop help users interact with structured and geospatial data in support of operational decision-making.

In this role, you will design and build front-end components for a production web application, improving how users interact with critical information in an enterprise environment. A key part of the work involves integrating front-end applications with REST APIs and back-end services to deliver seamless and reliable user experiences across the system. You will also contribute to improving usability, performance, and accessibility, while supporting interactive data visualization features that help users better understand and act on complex information.

While the platform supports geospatial intelligence workflows, the focus of this role is on front-end development, system integration, and user experience within a modern web application.
