Senior .Net Engineer

My customer is looking for a Senior .Net Engineer to join them on a fully remote contract basis for 6 months (likely to extend).

As the succesful Senior .Net Engineer you'll be joining the Head of Engineering on a greenfield build of a large-scale platform. This isn't maintaining legacy code — it's building something new from scratch using modern patterns and AI-assisted development. The platform already has a working prototype; you're helping take it to production.

As a Senior .Net Engineer, you'll be working across the full stack of backend services: building APIs, designing data models, implementing business logic engines, and making sure the platform scales.

Essential Skills:

* Strong .NET / C#

* Demonstrable experience with AI-assisted development (Copilot, Claude, Cursor, or similar)

* Experience building and designing RESTful APIs

* SQL Server — comfortable with schema design and query performance

Desirable:

* Entity Framework

* NoSQL (CosmosDB, MongoDB)

* Authentication and authorisation implementation (OAuth, OIDC, RBAC)

* Containerisation exposure
