What You’ll Do
As a Frontend Engineer, you’ll be at the center of creating an intuitive, high-performance trading experience:
Ship real-time trading features in React 18+ with TypeScript.
Design data flows with Redux Toolkit, Redux-Saga, and React Query (caching, optimistic updates, real-time sync).
Integrate APIs & live feeds via REST + WebSockets for order books, balances, and notifications.
Craft responsive UIs with Tailwind CSS + Styled Components, ensuring a seamless mobile-first experience.
Deliver rich visuals like candlestick charts, P&L dashboards, and live market visualizations using ApexCharts or similar.
Optimize performance with code-splitting, lazy loading, bundle budgets, and profiling.
Implement secure auth flows (JWT, OAuth, 2FA) and manage exchange API keys safely.
Contribute to internationalization (13+ languages, including RTL).
Raise the bar by mentoring peers, reviewing code, and shaping front-end architecture.
