Work across both legacy and modern Microsoft environments and help lead a genuine migration programme rather than just maintain old systems.

The business is growing and needs an experienced developer who can help move a core platform forward. Some of the estate is still in VB.NET, but the direction of travel is clear: modernising the codebase, improving architecture and helping drive the shift towards a more modern C# and .NET environment, with Azure and better engineering practices playing a bigger part.

You would be joining a software team that supports applications used in a regulated healthcare setting. That means the work matters, but it also means security, reliability and data handling standards need to be taken seriously.

Senior .NET Developer
£60,000
Remote with quarterly office visits

This role is mainly back-end focused and would suit someone with strong C# / .NET experience who is also comfortable working with VB.NET. The split is roughly 75% C# / 25% VB.NET, so this is not purely legacy support. The real focus is helping drive the migration from older VB.NET systems into a more modern C# and .NET architecture.

You would be joining an established team of circa 10 engineers

What matters most:

• strong commercial C# / .NET experience
• VB.NET experience
• solid back-end development skills
• SQL / database understanding
• ability to improve and modernise existing systems

Nice to have:

• Azure
• CI/CD
• React
• Xamarin / .NET MAUI

The applications sit in a regulated healthcare environment, so reliability, security and good engineering judgement matter.

Package includes:

• Salary up to £60,000
• Remote working
• Quarterly office visits
• 25 days holiday + bank holidays
• 5% pension
• Life assurance
• Sick pay
• Private medical after probation
