Azure Integration Developer

Zaven is a software company from Wrocław, Poland. We build high-quality custom software for essential industries. Our focus is on practical results and trusting our people, not on strict rules or long processes. 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.

Project Overview:

Join a high-stakes integration project as we modernize a global enterprise's middleware landscape. We are currently in the process of migrating a massive integration platform from Microsoft BizTalk Server to Azure Integration Services (AIS).

We have successfully migrated numerous components over the last few years, and we are now launching a dedicated "Migration Factory" sub-project to rebuild a specific package of 28 critical interfaces. This is a greenfield-style team within an established framework, where you will have full architectural support but high autonomy in delivery.

The Scope of Work:

• Factory Delivery Model: Rebuild 28 inbound/outbound interfaces (JDE/NAV/ERP) from legacy BizTalk orchestrations to Logic Apps (Consumption).

• Architecture Modernization: Transition from BizTalk BRE to Azure Rule Engine and move from heavy canonical models to streamlined Logic App run states.

• High-Volume Logic: Handle interfaces that manage over 1,000 configurations across various ERP instances.

• Transformation & Mapping: Implement complex logic using XSLT executed via Azure Functions.

• Automated Lifecycle: Full ownership of IaC (Bicep) and CI/CD (Azure DevOps) using existing enterprise templates.

Technical Requirements

Core Requirements (Must-have):

• Advanced Azure Integration Services (AIS): Extensive commercial experience with Logic Apps, Azure Functions, Service Bus, and API Management.

• Senior-level Programming: Advanced knowledge of C# and the latest .NET ecosystem.

• Enterprise Integration Patterns (EAI): Proven experience in designing and implementing complex integration patterns (routing, transformation, aggregation).

• Mapping Expertise: Strong proficiency in creating, testing, and versioning XSLT transformations.

• DevOps/IaC: Hands-on experience with Bicep and managing release pipelines in Azure DevOps.

• Security: Practical knowledge of Azure Key Vault and OAuth2 (Client Credentials) authentication.

Nice to have (The "Migrator" Profile):

• MS BizTalk Server Legacy: Experience with versions 2013/2016/2020—specifically understanding Schemas, Mappings, Orchestrations, and the Business Rules Engine (BRE).

• GS1 Standards: Familiarity with GS1 XML message formats.
