.NET Developer

.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.
