Job description

Closure Technologies is seeking a UI/UX Engineer in McLean, VA who will conduct user research, lead UX strategy and design system development, and produce accessible, high-fidelity UI designs and prototypes for complex, high-visibility applications.

Clearance Requirement: TS/SCI with Polygraph

Key Responsibilities:

  • User Research & Analysis
    • Plan and conduct user research activities including interviews, usability testing, and feedback sessions with diverse user groups (e.g., analysts, SMEs, managers, data scientists).
    • Analyze and synthesize research findings into actionable insights, personas, user journeys, and workflow maps.
    • Document research findings and recommendations to support stakeholder understanding and buy-in, particularly in government settings.
    • Apply ethical, secure, and compliant research practices appropriate for classified or sensitive environments.
  • UX Strategy & Design Systems
    • Lead UX and UI efforts for complex, high-visibility applications.
    • Define, maintain, and evolve design systems and component libraries in collaboration with engineering teams.
    • Establish consistent interaction patterns, workflows, and design standards across multiple applications.
    • Create service blueprints and end-to-end experience maps to align cross-functional teams
  • UI Design & Prototyping
    • Develop interactive prototypes using tools such as Figma, Adobe XD, or similar, to explore concepts and validate user flows.
    • Produce high-fidelity UI designs that are accessible, usable, and visually consistent.
    • Ensure designs align with accessibility standards (e.g., WCAG) and applicable government design guidelines.
    • Document interaction behaviors, design rationale, and micro-copy to support implementation

Required Qualifications:

  • Active U.S. Government Security Clearance at the TS/SCI level with required polygraph.
  • Bachelor's degree in Design, Human-Computer Interaction, Psychology, Computer Science, or a related field (or equivalent experience).
  • Minimum 8 years of experience with a Bachelor's degree; or 7 years of experience with a Masters degree; or 6 years of experience with a Doctorate
  • Demonstrated experience conducting UX research, analysis, and synthesis (not UI-only).
  • Strong proficiency with design and prototyping tools such as Figma, Adobe XD, or equivalent.
  • Experience collaborating closely with product managers and engineering teams.
  • Ability to clearly articulate design decisions and research findings to stakeholders.
