Senior NextJS/React Developer | 4+ yrs | Bangalore

About the Role

We are looking for a Senior Web Engineer to architect and build the entire web experience using Next.js and React — a consumer-facing trading app with real-time data, SEO‑optimised public pages, and internal admin tooling.

What We’re Looking For

• You have built production web applications from zero to launch using Next.js.
• You are comfortable across the full web stack — SSR/SSG, real-time WebSocket handling, responsive design, and performance optimization.
• Ideally, you have worked on trading platforms, dashboards, or data‑rich fintech products.
• You take ownership of your codebase, care about developer experience, and can work independently to deliver high-quality, production‑ready code.

What You’ll Do

• Architect and build the Next.js web platform from scratch — project structure, CI/CD, component library, and design system.
• Build real-time, data‑intensive interfaces — live price rendering, interactive charting, and responsive dashboards.
• Build SEO‑optimised content pages and public‑facing discovery surfaces.
• Build internal admin and operations tooling — dashboards, data tables, configuration interfaces, and monitoring views.
• Define frontend engineering standards — component architecture, testing strategy, accessibility, and performance budgets.
• Own cross‑browser compatibility, Core Web Vitals, and responsive design across devices.
• Drive code reviews, mentor team members, and champion best practices across the web team.

Must‑Have

• 4+ years frontend engineering with React in production; 2+ years with Next.js specifically.
• Strong TypeScript skills and experience with SSR, SSG, and incremental static regeneration.
• Experience building real‑time features with WebSockets in web applications.
• Experience with Tailwind CSS or utility‑first CSS frameworks.
• Experience building both consumer‑facing and internal admin/dashboard UIs.
• Understanding of SEO best practices — structured data, meta tags, Core Web Vitals.
• Familiarity with CI/CD, CDN deployment, and web performance optimization.

Nice‑to‑Have

• Prior experience building trading platforms, brokerage dashboards, or fintech web apps.
• Experience with charting library embeds (TradingView, Lightweight Charts, Highcharts).
• Experience building complex admin portals with advanced table views, filters, and real‑time updates.
• Familiarity with search integration (Typesense, Algolia).
• Experience with accessibility standards (WCAG 2.1) and internationalization (i18n).
