  • Extensive experience with Tailwind CSS, SASS/SCSS, or CSS Modules, and familiarity with component-driven design systems.
  • Proficiency with browser DevTools, accessibility auditing tools such as axe and Lighthouse, and cross-browser testing platforms.
  • Background in Software Engineering or Frontend Development.
  • Ability to complete a 10- to 15-minute test to assess skills, if invited.
