Senior Backend Engineer

ROLE MANDATE

Build the backend services, APIs and orchestration layer behind the Sales Command Center. The role sits between the web/iOS experiences and Dynamics 365, creating reusable services that combine CRM information with data and workflows from other enterprise platforms.

• Build orchestration services combining CRM data, documents, customer context, sales workflows and other enterprise systems.
• Implement REST APIs, asynchronous workflows and event-driven integration patterns.
• Build Dynamics adapter / anti-corruption layers so UI and domain services do not become tightly coupled to CRM schemas.
• 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.
