Senior Web Engineer (Next.js / React)

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).
