• Integrate frontend applications with REST/GraphQL APIs
• Contribute to technical decisions around frontend architecture, tooling, and best practices
What We're Looking For
Required:
• Strong professional experience with React (hooks, component patterns, state management)
• Strong UI/UX sensibility - experience building clean, intuitive, and visually polished interfaces
• Proficiency in JavaScript/TypeScript, HTML5, and modern CSS (Flexbox, Grid, responsive design)
• Experience with state management tools (Redux, Zustand, React Query, Context API, etc.)
• Familiarity with frontend build tools (Vite, Webpack) and package managers (npm/yarn/pnpm)
• Experience consuming REST or GraphQL APIs
• Understanding of web performance, accessibility, and cross-browser considerations
• Experience with version control (Git) and collaborative workflows
Nice to Have:
• Experience with design systems or component libraries (e.g., Storybook, shadcn/ui, MUI, Tailwind CSS)
• Experience with testing frameworks (Jest, React Testing Library, Cypress, Playwright)
• Familiarity with Next.js or other React frameworks
• Experience working closely with UI/UX designers in tools like Figma
• Exposure to CI/CD pipelines and frontend deployment workflows
