Senior Frontend Engineer

We're a relatively small fintech team building live commodity market data tools for traders. We're looking for a Senior Frontend Engineer to help us build fast, reliable interfaces that traders rely on every day. You'll work closely with a tight-knit engineering team and have real ownership over what we ship.

• Build and maintain trader-facing features with a focus on performance and reliability
• Work with real-time data feeds and high-density data displays
• Collaborate across the team on architecture and technical decisions
• Help raise the bar on code quality, testing, and frontend best practices

• Strong Type Script skills and a solid grasp of the type system
• Deep experience with React, including hooks, state management, and performance optimisation
• Experience working with GraphQL APIs
• Hands-on experience with Web Sockets for real-time data streaming
• Experience using Web Workers to keep heavy processing off the main thread

• Experience with AG grid or other high-performance data grid libraries
• Familiarity with Tan Stack Query (React Query)
• Background in fintech, trading, or other real-time data environments

• You write clean, maintainable code and care about the details
• You think out loud and bring others into design discussions early, rather than disappearing and returning with finished work
• You give and take feedback well, and you'd rather get to the right answer together than be right alone
• You can own a feature end to end, but you know when to pull people in
• You enjoy solving hard problems and aren't afraid of a tricky bug

• Competitive salary
• 25 days holiday, contributory pension scheme
