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.

KEY RESPONSIBILITIES

• Build BFFs, domain APIs and reusable business services supporting the Sales Command Center.

• Implement secure integration with Microsoft Dynamics 365 / Dataverse.

• 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.

• Write unit, integration and contract tests and contribute to CI/CD quality gates.

• Troubleshoot production and integration issues across UI, APIs, backend services and Dynamics.
