Senior Backend Engineer

* Implement authentication, authorization, idempotency, retries, timeouts, circuit breakers, rate limits, caching and canonical error handling.

* Develop read models and caching patterns where high-volume requests should not directly hit Dynamics.

* Use Azure API Management, Service Bus / Event Grid, Key Vault and Azure Monitor / Application Insights.
