A Full Stack C# .NET Developer is required to join a high-performing operations technology team within one of London's most technology-driven financial services firms, operating across global commodity and derivatives markets. This is a full stack role with a strong C# .NET backend focus, working on operationally critical systems that support the post-trade processing of Exchange-Traded Derivatives (ETD). You'll be working across the full stack from React front-ends through to C# .NET services and data layers in a highly data-driven environment where accuracy, traceability and consistency are paramount.
This is a rare opportunity for a strong technologist to move into financial services at a firm that genuinely treats technology as a core part of its business rather than a support function. Domain knowledge is not a prerequisite; what matters most is full stack engineering depth, a methodical approach to data and a desire to work on complex, high-integrity systems. With a global footprint spanning 40+ offices, access to 60 exchanges, and a team of over 3,200 people, the investment in engineering talent, modern tooling and cloud-native infrastructure is substantial and ongoing.
The Team
The ETD Operations Technology team sits at the heart of the firm's post-trade ecosystem. They design and maintain the systems responsible for:
- Building and maintaining full stack C# .NET and React applications supporting post-trade operational workflows
- Processing and validating high-integrity transactional and position data across C# .NET services
- Supporting deliveries processing, segregation movements and settlement workflows
- Handling commission and fee calculations and operational adjustments
- Ensuring exchange-traded activity is accurately reflected across internal platforms and client accounts
The environment is data-intensive and operationally critical, built on modern C# .NET, React and AWS infrastructure. The team works closely with operations stakeholders, business analysts and QA to deliver reliable, production-grade solutions that meet strict regulatory and compliance standards.
