Build the Platform Behind Mission-Critical Geospatial Intelligence

Front-End Engineer (GEOINT | TS/SCI)
Quantico, VA


Overview
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.

What You’ll Be Doing
In this role, you will:
  • Building responsive UI components for a production intelligence system
  • Creating interfaces that help analysts access and visualize mission data
  • Integrating front-end applications with REST APIs and enterprise systems
  • Improving usability, performance, and accessibility of existing features
  • Supporting geospatial and data visualization functionality (D3.js, ArcGIS API)
  • Working with stakeholders to translate analytical needs into UI solutions
  • Troubleshooting and resolving front-end issues in an operational environment
Requirements
  • Active TS/SCI clearance
  • Bachelor’s degree in Computer Science or related discipline
    • Or 8+ years of equivalent experience in lieu of a degree
  • 4+ years of professional experience building front-end web applications in production environments
  • Strong experience developing responsive, single-page applications using modern JavaScript frameworks such as React, Vue.js, or Angular
  • Solid proficiency with JavaScript (ES6+), TypeScript, HTML5, and CSS3
  • Proven experience integrating front-end applications with REST APIs
  • Experience working with enterprise back-end systems, including ITSM platforms and geospatial data services
  • Ability to build UI layers over complex, data-driven systems
  • Experience with data visualization libraries such as D3.js or ArcGIS API for JavaScript
  • Experience supporting interactive or geospatial data-driven interfaces
  • Strong understanding of UI/UX design principles and user-centered design
  • Experience developing accessible applications, including Section 508 compliance
  • Experience with modern front-end tooling, including npm/yarn, Webpack/Vite, and Git version control
Desired
  • Front-end or accessibility-related certifications
