.NET Developer
Location: Office-Based | UK
Industry: Financial Services
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.
Current Tech Stack
*ASP.NET MVC 5
*.NET Framework
*C#
*Entity Framework 6
*SQL Server
*JavaScript / jQuery
*HTML & CSS
*Azure SQL VMs
Modernisation Roadmap
*Migration to .NET Core
*Azure App Services adoption
*Improved SOLID and TDD practices
*AI integrations
*Continued cloud optimisation
You will play an active role in shaping this transition.
What We Are Looking For
*Strong C# development experience
*Experience with ASP.NET MVC and .NET Framework
*Exposure to .NET Core
*Solid SQL Server and T-SQL skills
*Comfortable working full-stack in a backend-heavy role
*Strong communication skills
*Able to work collaboratively in an office-based environment
Desirable
*Experience migrating to .NET Core
*Azure exposure
*Experience with App Services
*Understanding of SOLID principles and TDD
*Mentoring experience
The Ideal Candidate
You will thrive here if you:
*Enjoy working with complex systems
*Are comfortable maintaining legacy code
*Are motivated to modernise and improve platforms
*Communicate clearly and confidently
*Want long-term impact rather than short-term project work
If you are a .NET Developer who can balance maintaining a live production system with helping move it toward modern architecture, we would love to hear from you.
