Were recruiting on behalf of a large international retailer in the middle of a major data modernisation programme — replatforming onto a modern Azure-based integration stack while retiring a legacy Mulesoft estate. Its a fast-paced, high-expectation programme with broad scope across multiple international markets, and they need someone who can hit the ground running.
Youll be hands-on building and operating integrations across APIM, Logic Apps, Function Apps, Service Bus and Event Grid, connecting enterprise SaaS platforms including Workday, Oracle Symphony and NetSuite into their data, finance and operational systems.

* Monitoring production integrations via Application Insights and Log Analytics; investigating and resolving failures.
* Supporting the Mulesoft to Azure migration — keeping legacy flows stable through wind-down.
* Contributing to CI/CD pipelines, peer code reviews, Agile ceremonies and UAT cycles.
* Documenting integrations clearly for both technical and business audiences.
What youll need
* 3+ years commercial experience as an Integrations Engineer.
* Recent hands-on production experience (within the last 12 months) with at least three of: APIM, Logic Apps, Function Apps, Service Bus, Event Grid.
* Comfortable writing Function Apps in C# or Node.js, with strong API skills — REST, JSON, OpenAPI, OAuth 2.0.
* Familiarity with Key Vault, Managed Identity, Application Insights and Log Analytics.
