Frontend Developer - High Frequency Trading

Role Description:

A successful systematic trading firm is seeking a highly skilled Front-End developer to tackle a unique technical challenge: processing massive datasets directly in the browser. This is not a typical Front-End role, you’ll be handling computational loads and real-time data joins at a scale usually reserved for back-end systems, all within a low-latency, high-performance environment.

What Makes This Role Unique:

This position demands more than standard UI implementation. They\’re looking for an engineer who:

• Understands JavaScript execution mechanics at a deep level
• Optimises memory management in data-intensive applications
• Designs high-performance UI systems for complex real-time data processing
• Leverages advanced computer science principles to enhance browser-based performance
• Processes and visualises massive tick-by-tick market data streams

Technical Requirements:

• 4+ years of software engineering experience
• Proven ability to handle massive real-time data streams
• Strong expertise in TypeScript and React
• Deep understanding of JavaScript performance optimisation
• Experience with memory management and execution strategies

What They Offer:

• Cutting-edge trading technology platform
• Intellectually stimulating engineering challenges
• Performance-based bonus
• Medical insurance
• Contributory pension scheme

This is a rare opportunity to take on deep engineering challenges within a Front-End context. You’ll be working on high-performance, real-time data systems that push the limits of browser-based engineering, gaining experience that’s hard to find.
