One of our global clients is looking for a Developer with strong C# engineering skills, solid React experience, and a genuinely mathematical mindset, to join a high-performing financial services technology team in London. This is a hands-on role building analytics, pricing, risk, and decision-support tools used directly by front-office and business-facing teams.
You’ll be working across robust C#/.NET backend services, modern React frontends, and data-heavy applications where accuracy, performance, and usability really matter. The ideal profile is someone who enjoys the crossover between quantitative problem-solving and modern software engineering; not just building screens, and not just writing models in isolation, but creating end-to-end tools that make complex financial data clear, usable, and actionable.
What you’ll do:
- Build and enhance front-office analytics and decision-support platforms using C#/.NET and React.
- Develop backend services and APIs supporting pricing, risk, analytics, modelling, and complex business logic.
- Build intuitive React-based UIs that allow users to interact with complex datasets, calculations, and workflows.
- Work closely with front-office, quant, risk, and engineering teams to turn complex requirements into reliable software.
- Contribute to tools involving pricing, scenario analysis, risk views, reporting, and data visualisation.
- Design scalable, maintainable systems that can handle data-intensive and computation-heavy use cases.
- Improve performance, accuracy, and usability across existing analytics platforms.
- Work with legacy systems where needed, while helping modernise and improve the overall engineering landscape.
- Apply strong mathematical and analytical thinking to solve complex real-world financial problems.
Requirements:
- Degree in a numerical or technical discipline such as Mathematics, Physics, Engineering, Computer Science, Quantitative Finance, or similar.
- A minimum of 5 years of strong hands-on experience with C#/.NET in a financial services, trading, investment, or analytics-driven environment.
- Good commercial experience with React and modern frontend development.
- Strong experience working with SQL databases and data-heavy applications.
- A strong mathematical, quantitative, or analytical background.
- Exposure to linear programming, optimisation techniques, or mathematical modelling would be highly relevant.
- Experience building tools around risk, analytics, modelling, reporting, or complex data workflows.
- Comfortable working across the full stack, with the ability to move between backend logic and frontend delivery.
- Strong understanding of software engineering best practice, clean code, testing, performance, and maintainability.
- Experience working with complex datasets, business logic, calculations, or financial models.
- Strong communication skills and the ability to work closely with technical and non-technical stakeholders.
