Senior .NET / Azure Developer

You are not a code monkey.
You build ecosystems.

At adesso Benelux, we do not develop standalone applications. We build complete Microsoft architectures in which .NET, Azure, Dynamics 365 CE, and the Power Platform converge.

For us, Azure is not a standalone platform.

It is the extension layer around Dataverse, Dynamics, and complex enterprise landscapes.

Do you enjoy working in environments where integration, security, and performance are prerequisites?
Where scalability is not a nice-to-have but a requirement?

Then this is for you.

You work at the intersection of custom development and Microsoft Business Applications.

• Developing modern applications and APIs with .NET (C#) and ASP.NET Core

• Building cloud-native solutions with Azure App Services, Functions, Storage, and messaging

• Designing RESTful services within enterprise Azure environments

• Realizing integrations and extensions around Dynamics 365 CE and Dataverse

• Developing middleware between D365, Power Platform, and external systems

• Integrating complex API landscapes within the Microsoft ecosystem

• Helping build CI/CD pipelines (Azure DevOps / GitHub Actions)

You work in multidisciplinary teams with solution architects, Power Platform consultants, and other senior developers.
