* Integrate approved upstream data and reconcile it with the outputs made available to consumers.
* Implement safe retries, repeatable ingestion, failure handling and controlled refresh.
* Apply service identity, access and release controls so each audience receives the appropriate information.
* Create integration and contract tests, monitoring, deployment configuration and recovery guidance.
Essential experience
* Experience with C#, Entity Framework Core (EF Core), Microsoft Azure, and .NET Core / .NET 8 / .NET 10

* Practical experience with idempotent processing, retries, observability and failure recovery.
* Ability to diagnose integration defects and work closely with data and frontend engineers.
Assignment focus

* Public APIs: implement the agreed query, classification and release behaviour for external consumers.
* The position uses the Azure services and backend language selected for the solution; experience is assessed against that implementation.
