About Our Client

Our client is building a cutting-edge AI-powered cryptocurrency trading platform. The product delivers automated trading bots (DCA, Grid, Quantum), portfolio management tools, real-time market data, and multi-exchange integrations (Binance, Bybit, OKX, and others).

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

You'll Be a Strong Fit If You Have

• Solid expertise in React (18+) + TypeScript and modern ES2020+.
• 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.

What Success Looks Like

You'll deliver high-impact features for a global trading audience, ensure the platform is fast, reliable, and secure, and shape the front-end architecture of a product scaling at speed.
