Senior Software Engineer C#.NET

You’ll be joining an established engineering function working on highly scalable, production critical financial systems. The environment is centred around C#, ASP.NET, .NET Core, microservices and AWS, with a strong focus on clean architecture, SOLID principles, performance and engineering quality.

The engineering team is also increasingly adopting AI assisted development. We’re particularly interested in engineers who actively use modern AI coding tools such as GitHub Copilot, Claude Code, Cursor, Codex or similar to improve development, testing, debugging, code review and delivery.

You’ll be expected to remain highly hands on, writing scalable production code while contributing to architecture, improving the existing codebase, reducing technical debt and working closely with product and wider technology stakeholders. The wider environment includes AWS, Octopus Deploy, TeamCity and Jira.

We’re looking for strong commercial experience across C# and .NET, ideally within distributed or high performance systems. Experience within FinTech, financial services or another regulated environment would be valuable, although it isn’t essential.

This is an opportunity to join a business undergoing genuine technology change, where you’ll have the opportunity to influence how modern software engineering and AI assisted development are used across the organisation.
