• Maintain a strong focus on accessibility (a11y) and UX consistency

Data Fetching & API Integration

• Manage data fetching, caching, and synchronization using TanStack Query (React Query) or similar libraries
• Integrate backend APIs using Axios (or Fetch) and handle responses, errors, and loading states
• Implement predictable loading patterns, retry logic, and error boundaries where required

Routing, State, and Application Patterns

• Handle client-side routing using React Router (react-router-dom, v6+)
• Manage state using Context API and useReducer, applying modern React patterns
• Understand React rendering behavior and optimize component update cycles when needed

Internationalization & Product Readiness

• Implement internationalization using react-i18next (or similar)
• Support scalable localization patterns and UI layouts across multiple languages
• Contribute to shared component libraries and improve UI consistency across products

Engineering Practices

• Write clean, maintainable, well-documented code following best practices
• Participate in code reviews and contribute to team standards
• Collaborate with designers and backend engineers to plan and deliver features efficiently

Requirements

• 2–4 years of frontend development experience with a focus on React
• Strong skills in JavaScript (ES6+), TypeScript, HTML5, and CSS3
• Solid understanding of JavaScript fundamentals (closures, async/await, Promises) and OOP principles
• Experience building UI using MUI or similar component libraries (Chakra UI, Ant Design, etc.)

• Familiarity with modern tooling such as Vite/Webpack, npm/yarn, ESLint, and Prettier

Nice to Have

• Experience with Redux Toolkit, Zustand, Recoil, or other state management libraries
• Knowledge of React performance optimization (memoization, avoiding unnecessary re-renders, code splitting, useMemo/useCallback)
• Experience with frontend testing tools such as Jest, React Testing Library, Vitest, or Cypress
• Strong accessibility know-how (WCAG/ARIA) and attention to UI/UX details
• Familiarity with CI/CD workflows and basic monitoring/debugging practices (e.g., browser devtools profiling)

Personal Competencies

• Structured and detail-oriented engineering mindset
• Strong ownership and ability to deliver independently
• Good communication skills and ability to work across product and engineering teams
• Practical approach to balancing speed, quality, and maintainability
