• 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.

Our Profile:

We are an IT company with a unique mission—to make people the center of every federal IT solution. Our technologists have always gone the extra mile to help our federal clients succeed. And over the years, we saw a growing disconnect in how federal IT initiatives were built and managed. Time after time, programs failed because the focus was on the tools and products and not the people using them.

NuAxis is an Equal Opportunity Employer. Employment is contingent upon successful completion of a background investigation. about our Benefits and Culture!
