  • Participate in the full software development lifecycle, from requirements gathering to deployment and maintenance.
  • Write clean, well-documented, and testable code.
  • Collaborate effectively within an agile development team.
Required Experience/Clearance

  • Experience in one or more modern UI frameworks like React, Angular, or Vue.js.
  • Experience interfacing with end-users to understand their needs and translate into technical requirements.
  • Experience developing UIs for applications displaying sensitive information with stringent policies governing data access.
  • Active TS/SCI with Polygraph
Desired Experience
  • Experience with testing frameworks and methodologies for UI development.
  • Experience with responsive design and cross-browser compatibility.
  • Experience working with RESTful APIs and backend integration.
  • Experience using version control systems like Git.
  • Familiarity with Agile development methodologies.
