Job Summary
In this role, you will develop cloud features, integrate REST APIs, optimize provisioning processes, and implement AI agents for software development, while also increasing test coverage and ensuring technical quality.
Job Technologies
Your role in the team
- You develop new features in our Cloud Marketplace and management portals - from the booking process to subscription management for end customers and resellers.
- You develop and maintain our provisioning processes - from sync and batch jobs to workers that automate the deployment, modification, and billing of Microsoft 365, Azure, and Hosted Exchange.
- You integrate external systems via REST APIs, such as Microsoft Graph, Partner Center/CSP, Hornetsecurity, and Business Central - including authentication, webhooks, as well as robust error and retry handling.
- You independently implement features with Claude Code and AI agents: You prepare the necessary context, have agents take over parts of the implementation, and critically review their results.
- You develop our project knowledge in CLAUDE.md and Claude Skills further so that insights can be utilized by the entire team and our agents.
- You will further develop our jobs and queue platform based on Azure Service Bus and Docker/ACR to ensure that even larger processing runs operate reliably and errors remain traceable.
- You specifically increase test coverage where errors are particularly critical – for example, in provisioning, license assignment, and billing – and verify your changes before they go live.
- You take responsibility for the technical quality of your implementation and scrutinize AI-generated code just as critically as code you write yourself.

Our expectations of you
Qualifications
- Ideally, you have already worked intensively with Claude Code. However, what is most important to us is that you know how to prepare, implement, and subsequently verify tasks for Coding Agents.
- You want to understand generated code before it goes into production: you review it critically, secure important functions with tests, and take responsibility for the outcome.
- Excellent German and English skills.
Experience
- Several years of practical experience in software development with C# and .NET, particularly in web and backend development, ideally on production systems with complex business logic.
- Experience with modern .NET applications. We primarily work with .NET 8 or newer; individual legacy services still run on .NET Framework 4.8.
- Practical experience in implementing features with AI coding tools or AI agents that go significantly beyond autocomplete or single code suggestions.
- Proficient in T-SQL, a good understanding of data models, and practical experience with an ORM such as NHibernate or Entity Framework.
- Experience in integrating REST APIs, including authentication and webhooks. Topics such as retries, timeouts, and idempotency are part of a robust integration for you.
