We're looking for a Senior UI/UX Software Developer to help design and build modern, intuitive web applications supporting mission-critical systems. This is a unique opportunity to combine user experience design, frontend engineering, and information architecture to transform complex tools into seamless, user-friendly solutions.

If you enjoy solving hard problems, simplifying complexity, and building clean, elegant interfaces-this role is for you.

This role is HYBRID and can report to Annapolis Junction, Md., Reston, Va., or Washington, DC.

What You'll Do

Design User-Centered Experiences

  • Evaluate existing applications and identify usability improvements
  • Translate complex requirements into wireframes, workflows, and intuitive designs
  • Conduct user research and usability testing to drive design decisions

Build Modern Web Interfaces

  • Develop responsive web applications using React, Angular, or Vue
  • Create clean, maintainable code with HTML, CSS, and JavaScript
  • Integrate applications with APIs and backend services

Shape Information Architecture

  • Organize complex data into clear navigation and structures
  • Design layouts that make information easy to find and use

Own the Design System

  • Build and maintain reusable UI components in Figma
  • Ensure consistency across all products and interfaces

Ensure Accessibility

  • Design and build interfaces compliant with Section 508 standards

️ Collaborate in Agile Teams

  • Work within Agile/Scrum environments
  • Contribute to user stories, documentation, and sprint delivery

What Is UI/UX (and Why It Matters Here)?

In this role, you'll directly impact how users interact with complex systems:

  • UX (User Experience): Focuses on how easy and efficient the system is to use
  • UI (User Interface): Focuses on how the system looks and behaves visually

Your work ensures users can complete tasks faster, with fewer errors, and less training-a critical need in high-stakes environments.

Required Qualifications

  • Active TS/SCI clearance with Polygraph

  • 13+ years of experience (or equivalent education/experience combination)

  • Strong experience with:

  • UI/UX design and usability principles

  • Frontend frameworks (React, Angular, or Vue)

  • HTML, CSS, JavaScript

  • Figma (components, prototyping)

  • Experience integrating with REST APIs

Nice to Have

  • Experience with Adobe XD
  • Familiarity with Node.js, Java, or AWS
  • Experience with real-time data (WebSockets)
  • Strong background in user research or usability testing

Why Join Us?

  • Work on mission-critical systems that make a real impact
  • Collaborate with highly skilled, multidisciplinary teams
  • Influence both design and development decisions end-to-end

Compensation:

$170,000- $195,000 depending on years of experience
