Job description

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.

Requirements

Hands-on experience with Redux Toolkit, Redux-Saga, and React Query in production.
Proven work on real-time systems (WebSockets, live market data, large datasets).
Experience with charting libraries (ApexCharts, Highcharts, D3, etc.) including live updates.
Strong understanding of performance optimization.
Awareness of secure authentication flows and API key management.

Leveling guidance:

Mid-level: ~3-5 years React/TS experience.
Senior-level: 5+ years with architectural or product-wide impact. ???? Impact > years of experience: if you can demonstrate senior-level contributions, you’ll be considered at that level.

Bonus Skills

Trading/fintech background (order forms, risk, real-time systems).
Testing with Jest + React Testing Library.
Familiarity with CI/CD pipelines.
Monitoring/analytics (Sentry, Datadog, PostHog).
Experience with PWAs or Web3/wallet integrations.

???? What Makes You Stand Out

Problem-solving mindset in complex, data-heavy contexts.
Collaborative and proactive in Agile teams.
Clear communication, clean documentation, thoughtful peer reviews.
