If you want to work with smart teams to build important software, and you want to avoid big company bureaucracy, this is the place for you. We are looking for an experienced Azure Integration Developer and a true Azure Logic Apps enthusiast - to join a large migration project for our international client. The goal is to rebuild ~30 complex integration interfaces (message exchange between ERP systems like JDE, NAV, and external systems) into a modern, 100% cloud-native environment based on Azure Integration Services (AIS) using a Factory Delivery model. Your task will be to build the integration logic from scratch in the Microsoft Cloud. You don't need to know the legacy system we are migrating from – what matters most is how well you can build reliable, scalable integration processes in Azure. What you will be doing: Building new integration flows primarily based on Azure Logic Apps . Creating and deploying data transformations (often based on XSLT/XML/SOAP) using Azure Functions . Handling asynchronous communication and message routing using Azure Service Bus . Developing solutions according to the prepared target architecture (specific Inbound / Outbound patterns). Integrating with other cloud services: API Management, Azure Key Vault, Azure App Configuration. Following development standards – including Infrastructure as Code ( Bicep ) and CI/CD processes ( Azure DevOps ). Required Skills & Experience: Azure Logic Apps – this is a hard requirement. You must have commercial experience in building, maintaining, and monitoring Logic Apps. .NET / C# – fluent coding skills, especially in the context of Azure Functions. Azure Functions – ability to create functions from scratch, strong understanding of triggers and bindings. Azure Service Bus – solid understanding of queues, topics, subscriptions, and asynchronous messaging patterns. Integration Experience – strong grasp of integration patterns (EAI), data mapping, error handling, and monitoring in distributed systems. Nice to have: Hands-on experience and fluency in using Azure API Management . Experience with XSLT / XML transformations and familiarity with SOAP / REST protocols. Experience with Infrastructure as Code, preferably Bicep (alternatively ARM Templates / Terraform). Knowledge of Azure DevOps (creating and maintaining CI/CD pipelines). Familiarity with Azure Event Grid. Any knowledge of Microsoft BizTalk Server is a plus (it will help with reading legacy code), but it is not required.
