C++ Developer – Market Data – Fast Scaling FinTech

A fast-growing fintech scale-up is looking for a C++ Developer to join its core market data team. This group sits at the heart of the business – everything the company delivers starts with the systems they build. It’s a fast-paced environment where engineers see the direct impact of their work and help shape products used across global finance.

About the role:

This role sits at the centre of their data engine, working on systems that power every product the company delivers. You’ll develop high-performance components in modern C++ and help evolve the pipelines that handle massive, fast-moving datasets. Expect to solve complex engineering problems, shape how data flows through the platform, and contribute to projects that ship quickly and visibly. The work is hands-on, collaborative, and full of variety – no two days look the same.

About you:

• Strong modern C++ and confident working on Linux
• Experience with financial data or other large-scale datasets; market data experience is ideal
• Comfortable reasoning about data structures, algorithms and performance
• Communicative, collaborative, and motivated to understand data deeply rather than just write code

Benefits & process:

• Discretionary bonus
• Hybrid working style
• 40 days per year working abroad
• Training budget, collaborative culture, regular team lunches and socials
