  • Experience integrating with RESTful APIs
  • Experience with version control systems (Git)
  • Ability to work onsite in Chantilly, VA

Preferred Qualifications

  • Experience with modern build tools and deployment pipelines
  • Knowledge of UI testing frameworks
  • Exposure to cloud environments (AWS, Azure, or GCP)

What Youโ€™ll Bring

  • A strong eye for visual detail, layout, and user experience
  • Passion for creating intuitive and aesthetically polished interfaces
  • Well-tested, maintainable code
  • Ability to balance design fidelity with technical performance
  • Strong collaboration and communication skills across geographically distributed team
  • A proactive mindset and attention to continuous UI improvement
