🌐 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:
- Deliver rich visuals like candlestick charts, P&L dashboards, and live market visualizations using ApexCharts or similar.
- 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.
- 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.
- 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.
🧑💻 You’Ll Be A Strong Fit If You Have
- Strong understanding of performance optimization.
- Awareness of secure authentication flows and API key management.
- Mid-level: ~3–5 years React/TS experience.
Leveling Guidance:
- 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.
