We are seeking an experienced UI/UX Designer to lead human-centered design efforts for mission-critical applications supporting government users. This role is responsible for end-to-end UX and UI design, from user research and analysis through interaction design, prototyping, and delivery. The ideal candidate brings a strong balance of research-driven UX practice and high-quality visual/UI design and is comfortable operating within the constraints of government environments.

• 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.

Minimum Qualifications: 

• Bachelor’s degree in Design, Human-Computer Interaction, Psychology, Computer Science, or a related field (or equivalent experience).

• Minimum of 5 years of professional experience in UI/UX design.

• 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.

• Willingness to work onsite full time in McLean, VA.

Preferred Qualifications: 

• Portfolio (website, case studies, or work samples) demonstrating UX research methodology, analysis, and UI design quality.

• Experience designing for mission-critical or government systems.

• Familiarity with accessibility standards (WCAG) and inclusive design practices.
