  • Solid understanding of REST APIs, Graph

  • Experience with testing frameworks (Jest, React Testing Library, Cypress, etc.).
  • Familiarity with build systems and tooling (Webpack, Vite, Babel, etc.).
  • Knowledge of web performance optimization and accessibility standards (WCAG).
  • Excellent communication skills and a collaborative mindset.
  • Experience in mentoring or leading engineers is a plus.
