* Strong German and English language skills
* 7+ years of professional experience in .NET (C#) development, including development of Entity Framework-based solutions
* 3+ years of hands-on experience architecting and deploying solutions in Microsoft Azure
* Strong grasp of established architecture patterns
* Experience with Azure services like Azure App Services, Functions, Azure SQL, Azure Storage, Key Vault and such.
* Solid understanding of Azure DevOps CI/CD pipelines
* A pragmatic mindset with a strong focus on performance, reliability, cost-efficiency and maintainability
* Excellent communication and stakeholder management skills — you can speak to both code and business value
* Azure Certifications (share a link to your transcript for us)
* Contributions to open-source projects or tech blogs
* Frontend development knowledge
* Knowledge of a data platform, such as Microsoft Fabric or Databricks.
What We Offer
* Competitive compensation + benefits (such as GA Abo, fitness studio membership, lunch card, and others)
* Remote possible, with offices and team presence in Winterthur, Switzerland
* A tight-knit team of world-class engineers who love what they do
