We are looking for a Senior Design System Engineer / Senior UI Engineer with strong hands-on experience building and implementing enterprise design systems, reusable component libraries, and accessible Angular applications.

The strongest candidate will have experience taking a design system from initial setup through implementation, building reusable components, documenting components in Storybook, and applying WCAG 2.1/AAA and Section 508 requirements throughout front-end development.

This is a hands-on engineering role focused on design systems, accessibility, Angular component development, and front-end architecture.

• Semantic HTML
• Keyboard accessibility
• Accessible UI components
• Accessibility testing
• Accessibility remediation
• Accessibility audits/reviews

Front-End Engineering

Strong experience with:

• Angular
• HTML5
• SASS / SCSS
• Reusable Angular components
• Component libraries
• Front-end architecture
• UI component development

Storybook

Hands-on experience using Storybook for:

• Component development
• Component documentation
• Component demonstrations
• Collaboration with development teams
• Maintaining reusable component libraries

Enterprise Design Systems

Experience with USWDS or another enterprise-level design system is required.

Preferred Experience

• .NET
• MVC
• SQL
• Experience integrating Angular applications with .NET-based back-end systems
• Government or public-sector application development
• Large enterprise application environments
• Accessibility remediation across multiple applications, The ideal candidate is a Senior Design System Engineer, Senior UI Engineer, Senior Front-End Engineer, UX Engineer, or Front-End Architect who combines strong engineering skills with deep accessibility expertise.

The candidate should be able to demonstrate that they have:
