Responsibilities

• Build and maintain reusable, accessible React + MUI components, patterns, themes, and utilities.

• Automated testing experience with Jest and/or React Testing Library.

Nice-to-haves

• Accessibility experience (semantic HTML, ARIA, WCAG).
• Storybook, component documentation and/or visual regression testing.
• Angular experience.
• CI/CD, npm package publishing, private registry experience.
• Figma-to-code workflows.
• Prior work on an internal platform or shared library rather than only product/feature teams.

What a strong CV looks like

Prioritize resumes showing design system, component library, or shared UI platform work, with keywords like: React, TypeScript, MUI/Material UI, Storybook, design tokens, WCAG/accessibility. Product/feature-only React experience is acceptable for this level.
