At Maven we allocate internal capital across discretionary, systematic, and market-making strategies, bringing together traders, engineers, and technologists who share a single goal: to become the most efficient liquidity provider for globally listed derivatives. We build and run proprietary execution and pricing systems that improve how financial markets operate every day.
The role
We are hiring a Senior C# Developer to join the Interactive Trading team on a full-time, on-site basis in the United Kingdom. You will work alongside traders and business stakeholders to design, build, and maintain the front-office trading systems that power our options market-making desk.
Core responsibilities
- Partner directly with front-office users to capture requirements and translate them into reliable, high-performance software.
- Design and develop mission-critical back-end services and web front-ends, emphasising performance, maintainability, testability, and resilience.
- Write clean, well-tested code, automate repetitive tasks, and collaborate with Site Reliability Engineers and infrastructure teams to deliver and operate robust systems.
Skills and experience
You bring expert-level C# skills and a solid grasp of testing practices on the .NET platform, currently running .NET 8 and moving to .NET 9. Experience with CI/CD pipelines, Docker, and Kubernetes is essential. Strong analytical thinking and the ability to communicate design decisions clearly round out the profile. English fluency is required.
Compensation and benefits
We offer competitive compensation, an annual discretionary bonus, and a group pension plan. Additional benefits include 25 days of annual leave, fully catered breakfast, lunch, and snacks, private healthcare and life assurance, a cycle-to-work scheme, access to a private gym, monthly company events, and an informal dress code.
