React (NextJS) Lead

Key Responsibilities

• Lead the technical direction for the React and Next.js codebase, ensuring modularity, scalability, and maintainability.
• Define architectural patterns including: Component architecture and atomic design, Layout systems, State management strategy (Redux, RTK Query, Zustand, Recoil, Context API), Routing and navigation patterns in Next.js, SSR, ISR, SSG strategies.
• Work closely with the Web Architect to align on frontend technical vision.
• Establish standards for folder structure, naming conventions, code patterns, and component documentation.
• Define the strategy for: Server-Side Rendering (SSR), Static Site Generation (SSG), Incremental Static Regeneration (ISR), Edge rendering and caching policies, Optimize data-fetching using: getServerSideProps, getStaticProps, getStaticPaths, New Next.js App Router features (server components, client components), API routes, middleware, and edge functions.
• Ensure correct handling of hydration, loading states, caching, and route transitions.
• Lead integration with enterprise design systems (e.g., Storybook, Material UI, Chakra UI, custom component libraries).
• Ensure components follow accessibility guidelines (WCAG 2.1 AA).
• Conduct UI performance optimization related to UI rendering, layout shifts, and Core Web Vitals.
• Own performance tuning efforts for: Largest Contentful Paint (LCP), First Input Delay (FID), Cumulative Layout Shift (CLS), Time to Interactive (TTI), Memory usage and rendering speed, Optimize bundling and build processes: Code splitting, Tree shaking, Lazy loading, Server and client-side caching.
• Monitor and diagnose performance issues using: Lighthouse, Web Vitals reports, Chrome DevTools, Next.js analyzer.
• Define enterprise-grade state management strategies using: Redux Toolkit, RTK Query, Zustand, Context API + Hooks, React Query / SWR.
• Implement data normalization, caching layers, prefetching, optimistic updates, and error boundaries.
• Ensure predictable and traceable application state flows.
• Partner with BFF developers to define efficient, secure data contracts.
• Implement authentication and authorization flows: OAuth2, JWT, SSO / SAML if applicable.
• Handle robust error handling, retries, fallbacks, and data validation.
• Enforce secure API consumption patterns and CORS best practices.
• Lead code reviews with a focus on: Performance, Security, Maintainability, Accessibility, Best practices and style standards.
• Mentor developers through pair programming, technical workshops, and architectural guidance.
• Define coding standards for: TypeScript, React hooks usage, Custom hooks development, Component reuse, API consumption patterns.
• Collaborate with DevOps to optimize: CI/CD pipelines for web builds, Linting and formatting tools (ESLint, Prettier), Automated testing frameworks (Jest, RTL, Cypress, Playwright), Static analysis tools.
• Optimize build performance and environment configuration through Next.js settings.
• Define test hierarchy: Unit tests, Component tests, Integration tests, E2E tests.
• Implement testing frameworks: Jest + React Testing Library, Cypress or Playwright for E2E.
• Ensure proper mocking of APIs, services, and data flows.
• Enforce frontend security best practices: Avoiding XSS vulnerabilities, Securing API tokens, Sanitizing inputs, Preventing CSRF, Using secure cookies, Implementing role-based access controls and secure routing.
• Ensure compliance with enterprise standards for: Data separation, User access, Privacy policies, Logging & observability.
• Document architectural decisions (ADR logs).
• Maintain developer onboarding guides and coding standards.
• Create reusable component documentation and Storybook setups.
• Write technical specifications for complex front-end features.
