  • Collaborating closely with designers on component behavior, styling, and design handoff

  • Helping improve the quality, consistency, and maintainability of shared frontend code

  • Participating in code reviews for the shared UI codebase and related integrations

  • Experience integrating shared UI Kit components into applications

  • Quality, ownership & engineering mindset

  • Good understanding of software testing fundamentals for frontend applications (unit, UI, integration, component tests)

  • Proactive mindset and readiness to take ownership of assigned UI Kit areas and tasks

  • Ability to work independently on well-defined problems and ask for support when needed
