About the Role

You will build and maintain the web front-end of a high-traffic exchange: live trading screens, wallet and deposit/withdrawal flows, KYC onboarding, and marketing pages. Every screen handles real money and real-time data, so speed, accuracy and security matter as much as design. You will work closely with backend, product, design and security teams, and own your features from Figma to production.

Key Responsibilities

Build fast, responsive SSR/SSG/ISR pages in Next.js (App Router) using React and TypeScript, including Server Components and server actions where they fit.

Develop real-time trading interfaces, order books, live tickers, trade history, order placement and portfolio views, that stay smooth under heavy WebSocket traffic.

Integrate REST and WebSocket APIs for live prices, order books, balances and order status, with reconnection, throttling and error handling built in.

Build secure user flows: sign-up, login, OTP, 2FA, KYC onboarding, deposits, withdrawals and wallet management.

Own Core Web Vitals (LCP, INP, CLS), SEO (metadata, structured data, sitemaps) and accessibility (WCAG 2.1 AA) across the web app and marketing pages.

Convert Figma designs into pixel-accurate, reusable components and help maintain a shared design system.

Apply front-end security practices: secure token handling, XSS/CSRF protection, Content Security Policy and safe handling of sensitive user data.

Manage client and server state cleanly with React Query, Zustand or Redux, and keep displayed balances and prices accurate.

Write unit and integration tests, review peers' code,



and ship through CI/CD pipelines with Git-based workflows.

Monitor production issues, fix bugs quickly, and work with backend, QA and product teams on releases.

Must-Have Skills

3–5 years of professional front-end development, with at least 3 years in React and 2+ years in Next.js on production apps.

Strong TypeScript and contemporary JavaScript (ES6+).

Next.js App Router, SSR/SSG/ISR, routing, middleware, and caching/revalidation.

Styling with Tailwind CSS and/or CSS Modules; responsive, mobile-first layouts.

State and data management with React Query, Zustand or Redux.

Authentication flows: JWT (access/refresh tokens), OTP and 2FA.

REST and WebSocket API integration for real-time data.

Proven work on Core Web Vitals, technical SEO and accessibility.

Git (branching, pull requests, code reviews) and CI/CD basics (e.g. GitHub Actions, Vercel or Docker-based deploys).

Clear communication and ownership of features end to end.

Good to Have

TradingView charting library (Advanced Charts or Lightweight Charts) integration.

Internationalisation (i18n) and multi-language support, including Hindi.

Experience on a fintech, payments, trading or crypto product.

Familiarity with crypto basics: spot trading, order types, wallets, deposits/withdrawals, and blockchain networks.

Testing with Jest, React Testing Library, Playwright or Cypress.

Performance tooling: Lighthouse, Web Vitals monitoring, bundle analysis.

Error and analytics tools such as Sentry, Google Analytics or Mixpanel.

PWA or React Native exposure.
