Full Job Description
Role Summary

Designs and builds the user experience for high-volume, public-facing digital services used by a broad and diverse population. Combines human-centered design research with hands-on accessible front-end implementation, so designs ship rather than sitting in a design tool.

• Conduct human-centered design activities: user research, journey mapping, personas, task analysis, and usability testing.
• Produce wireframes, interactive prototypes, and high-fidelity designs; maintain a design system and component library.
• Implement responsive, mobile-first front-end code (HTML5, CSS3, JavaScript) integrated into the CMS theme layer.
• Design and build complex multi-step forms with progressive disclosure, inline validation, save-and-resume, and clear error recovery.
• Own accessibility from design through delivery - WCAG 2.1 AA, semantic markup, keyboard navigation, focus management, ARIA where required.
• Apply plain-language and content design principles for low-literacy and limited-English-proficiency audiences, including bilingual layouts.
• Validate designs with analytics, A/B testing, and usability findings; iterate on evidence.
• Partner with developers and testers to ensure implemented UI matches design intent and passes accessibility validation.
• Implement designs using USWDS and coordinate with DOL Digital Transformation/SORT stakeholders; ensure consistency with DOL.gov patterns and the 21st Century IDEA.
• Validate designs across current and previous major browsers, desktop/tablet/mobile form factors, keyboard-only interaction, screen readers, and responsive breakpoints.
• Design for bilingual English/Spanish content, complex public forms, real-time validation, clear error recovery, and low-literacy/limited-English-proficiency users.
Required Skills & Experience
• 5+ years combined UX design and front-end development for public-facing or enterprise web applications.
• Proficiency with Figma (or equivalent) and design system maintenance.
• Strong hands-on HTML5, CSS3 (Sass/Tailwind/Bootstrap), and JavaScript; ability to implement your own designs.
• Demonstrated WCAG 2.1 AA / Section 508 accessible design and development practice.
• Human-centered design methods including moderated usability testing.
• Experience designing within a CMS theming context (Drupal Twig or comparable).
• Responsive and mobile-first design fluency across devices and assistive technologies.
• Hands-on USWDS implementation experience and strong understanding of federal digital-service design standards.
• Ability to pair design artifacts with measurable usability/accessibility acceptance criteria and support automated/manual QA validation.
Preferred Qualifications
• Experience with federal design standards and public-sector service design.
• Bilingual (English/Spanish) content and layout design experience.
• Front-end framework experience (React, Vue) for interactive components.
• Familiarity with analytics-driven design optimization.
