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.

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.

ASP.NET – MVC 5 – .NET Framework – C# – Entity Framework – 6 SQL Server – JavaScript / jQuery – HTML & CSS Azure SQL VMs

• 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.

• 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

• Experience migrating to .NET Core
• Azure exposure
• Experience with App Services
• Understanding of SOLID principles and TDD
• Mentoring experience

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.
