Front-End React Software Engineer : Trading : £120-180k plus excellent bonus : London
The Role
You’ll take ownership of complex, data-rich web applications that surface live market data, research insights, and trading activity in real time. These are mission-critical tools used by traders and quantitative researchers operating in fast-moving environments.
Expect to think deeply about latency, rendering performance, and information density, not just UI polish. You’ll work side-by-side with backend engineers, quants, and traders to design interfaces that remain fast, reliable, and intuitive even when the data is moving quickly and the stakes are high.
Key Responsibilities
- Build and evolve advanced React applications used in live trading and research workflows
- Design scalable front-end architectures and reusable component systems
- Optimise performance for real-time, high-volume data visualisation
- Partner with backend engineers on APIs, data contracts, and system design
- Deliver well-tested, maintainable code with a strong bias toward correctness and reliability
