Their mission: to provide institutional-grade trading capabilities with consumer-grade UX — making advanced trading accessible, fast, and reliable.

Ship real-time trading features in React 18+ with TypeScript.

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.
