???? 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.

• 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+.

• 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.

• 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.
