About the Role
This role will focus on modernising and evolving a large legacy platform currently built on .NET Framework. The team is in the process of migrating the system to a modern .NET architecture, requiring significant refactoring and the gradual transition from a monolithic application to scalable services connected through modern Web APIs.

The platform is hosted in Azure, and you will contribute to scalable API design, secure authentication patterns and modern deployment practices as the platform continues to evolve.
