Front End Web Developer | TS/SCI

Quantico, VA

Overview

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.

Voluntary Self-Identification of Disability

Voluntary Self-Identification of Disability Form CC-305

OMB Control Number 1250-0005

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
