C# Software Developer - Investment Firm | Desktop Applications

A global investment firm managing ~$10bn in assets is looking for a Senior C# Software Developer to join their London tech team. With offices in London and the US, the firm trades across multiple asset classes including Fixed Income, operating in a fast-paced, collaborative environment. The tech team is lean and technically mature, with a strong emphasis on clean, maintainable code and thoughtful long-term system design.

The Role:

You'll be part of a small, experienced engineering group, responsible for developing and supporting critical desktop applications. The primary focus is WPF development, alongside light maintenance of existing WinForms tools. This is a high-ownership role - as the only developer in the London office, you'll enjoy significant autonomy while working closely with senior peers in other global locations. It's a great opportunity to work directly with the business and have real impact.

What You'll Do:

  • Build and enhance WPF-based desktop applications used by trading, risk, operations, and finance teams

  • Maintain and support legacy systems built in WinForms

  • Work with SQL for real-time data processing and reporting

  • Design scalable, service-oriented architectures using REST APIs

  • Collaborate closely with traders, risk managers, and operational staff to deliver tailored solutions

What We're Looking For:

  • 6+ years of experience developing desktop applications, with strong WPF and WinForms knowledge

  • Deep C# expertise with a focus on performance and maintainability

  • Solid SQL skills and experience working with relational databases

  • Experience supporting front or middle office users is a plus (back office experience also valued)

  • Comfortable working independently and owning the full lifecycle of applications

  • Bonus: familiarity with Python or cloud-based technologies but it's not a requirement

If this sounds like the right fit, feel free to apply with your updated CV and contact details for more info.
