Title: React Developer Location: Pune / Hyderabad / Mohali / Remote Responsibilities: - Lead design and implementation of user-facing features using modern React (function components + Hooks). - Design and deliver highly responsive, accessible, and pixel-accurate UIs from wireframes / prototypes. - Build and maintain a library of reusable React components and composable UI primitives (with Storybook). - Implement state management solutions: Context API for local/global concerns, and Redux (Redux Toolkit / middleware) for large-scale app state. - Create and publish Custom Hooks for cross-cutting concerns (data fetching, caching, form handling, feature flags). - Translate UX designs into performant React code using best practices (code-splitting, memoization, virtualization). - Ensure robust REST API integration with standardized error handling, retry/backoff strategies and typed response handling. - Drive test-first development: unit tests (Jest + React Testing Library), integration tests, and end-to-end tests (Cypress). - Own performance profiling and optimization across devices and browsers (Lighthouse budgets, bundle analysis, lazy loading). - Define and enforce accessibility (WCAG) and keyboard-driven interactions across components. - Mentor engineers, run knowledge transfer sessions, and coordinate cross-team integrations. - Produce and maintain project documentation, delivery artifacts, and compliance/audit evidence. - Reduce technical debt by proposing pragmatic refactors, architecture improvements and risk mitigations. - Collaborate with global/regional stakeholders and contribute to Agile/DevOps processes (CI/CD, code quality gates). Qualifications: - University degree in Computer Science or related discipline. - 8–10 years front-end experience; 3–6+ years hands-on with React in recent projects. - Deep proficiency in modern JavaScript (ES6+), DOM and browser internals. - Expert with React Hooks (useState, useEffect, useMemo, useCallback, useRef), Context API and writing Custom Hooks. - Strong experience with Redux (prefer Redux Toolkit), middleware (thunks/sagas/observables), and patterns for scalable state. - Experience with Styled Components (or similar CSS-in-JS) and ability to architect themeable component systems. - Practical experience with Bootstrap / Material UI and utility libraries like Lodash. - Test-driven development experience with Jest and React Testing Library; E2E testing with Cypress or equivalent. - Proficient with REST API integration, async flows, and robust client-side error handling. - Familiar with build tools (Babel, Webpack), package managers (npm/yarn) and modern dev tooling. - Accessibility-first mindset and keyboard-driven development experience (ARIA patterns). - Competent with browser debugging, performance profiling and tools (Chrome DevTools, Lighthouse). - Strong troubleshooting, benchmarking and optimization skills. - Toolchain experience: Git, JIRA, SonarQube, Jenkins, Postman, AppDynamics (or equivalents). - Cloud and test automation experience is a plus. - Domain advantage: Banking/Financial services experience. - Excellent written and verbal communication, documentation skills. - Comfortable mentoring, training and working in global, cross-timezone teams. - Agile and DevOps practical experience. Good To Have: - TypeScript experience in React codebases (recommended for large apps). - Familiarity with micro-frontend architectures. - Experience publishing and maintaining internal component libraries (npm registry, versioning). - Experience with CI pipelines, Sonar quality gates and automated release flows. Technical Skills: - React (latest stable) + Function Components + Hooks - Redux Toolkit for global state; React Context for local/global scoping - Styled-Components for CSS-in-JS and theming - Jest + React Testing Library; Cypress for E2E - Storybook for component library - TypeScript recommended - Webpack/Babel (or Vite for new projects), npm/yarn - CI: Jenkins/GitHub Actions; static quality: ESLint, Prettier, SonarQub
