The Role: Most React engineering jobs focus on customer-facing products. This one helps power technology used by financial markets around the world. You’ll build applications that help people trade on, monitor and control technology used across financial markets. You'd be building the web apps and desktop tools that traders and market operators use to trade on, monitor, and control exchange infrastructure. Every screen you ship carries weight. You’ll get ownership rather than a tightly defined list of tickets. Working with product, infrastructure, QA and UX, you’ll help shape the technical approach, challenge weak ideas and turn wireframes into reliable applications. You’ll also influence how the team builds software, including reviewing designs, improving engineering standards and supporting less experienced developers without becoming a full-time manager. The company develops technology for regulated financial markets. You don’t need previous trading experience, but you should enjoy solving technically complex problems where poor performance or unreliable code has a visible consequence.

What You’ll Build:

  • Building responsive, data-intensive web and desktop applications.
  • Integrating frontend applications with Python-based APIs.
  • Improving performance, accessibility, security and automated test coverage.
  • Contributing to technical reviews, CI/CD improvements and decisions around new tools, architecture and engineering practices.

What You’ll Need:

  • Experience building data-driven applications where performance, reliability and usability are important.
  • A solid understanding of automated testing, including unit, integration and end-to-end testing.
  • Familiarity with Python APIs will help, though you don’t need to be a Python engineer.
  • Experience with cloud platforms, Infrastructure as Code, containerised applications or financial markets technology would be useful, but none of these is essential.

How The Team Works: You’ll report to a Lead Software Engineer and join a team that values practical ideas, shared ownership and direct communication. People are trusted to make decisions, but you won’t be left to struggle alone. The team reviews work openly, shares technical knowledge and expects senior engineers to raise standards rather than protect their own corner. The London team works together in the office for at least three days each week, with the remaining time available for home working.

Interview Process: Full process shared during the initial confidential conversation.

Apply: Apply to receive the full briefing and arrange a confidential discussion about the team, technology and work you’d be taking ownership of.
