Are you a strong C# developer who enjoys working on real-world systems while helping modernise them?

We are hiring a .NET Developer to join a collaborative, office-based engineering team within an established UK financial services organisation. This role offers a rare opportunity to work on a live, customer-facing platform while actively contributing to its evolution toward modern .NET and Azure technologies.

This is not a pure greenfield role. It is not a legacy-only support role. It is a genuine blend of both.

The Role

You will work on a business-critical lending platform used daily by customers across the UK.

The role is approximately:

* 60% backend

* 40% front-end

You will:

* Maintain and enhance an existing ASP.NET MVC application

* Build and improve backend logic using C#

* Work with Entity Framework and SQL Server

* Write and optimise T-SQL queries

* Contribute to UI updates when required

* Help drive the ongoing migration to .NET Core

* Support the move to Azure App Services

* Contribute to improving engineering standards and practices

This is a hands-on, full-stack position with strong backend depth.
