Job description

You will work across the full stack — building the React interfaces traders rely on and the Node.js services that power them — solving performance, data throughput, and UX challenges that most engineers never encounter, working directly with the trading desk.

What the Full Stack Software Engineer will be doing:

• Design and build the Node.js services and APIs that feed those interfaces, handling high-volume, real-time market data
• Collaborate closely with front-office stakeholders and other engineers to translate trading workflows into robust, intuitive, end-to-end solutions
• Own the quality and architecture of both frontend and backend codebases — with genuine influence over technical direction
• Work within a distributed team across three global offices, with day-to-day presence in London

Requirements for the Full Stack Software Engineer:

• React expertise — you write clean, performant component architecture and know when not to use the framework.
• Solid, hands‑on Node.js experience — building and running real backend services, not just tooling or scripting.
• Proven ability building robust, high-volume applications (frontend and backend) under real-world performance constraints.
• Exposure to financial services, trading systems, or similarly demanding real‑time data environments is a genuine advantage — not a requirement, but it will set you apart.
• Strong communicator comfortable working across engineering, product, and trading desk stakeholders

Benefits package includes:

• Bonus up to 25%
• Private medical insurance
• Life insurance
• 25 days holiday
• Wellness benefits including gym membership
• x3 days in the office per week

If you have full stack engineering experience in a high-performance or data-intensive environment and want to work on software that genuinely matters to the people using it, we'd like to hear from you.
