Analyze and resolve issues: You will record support requests, reproduce errors, check potential causes, and document the resolution process in a comprehensible manner. In doing so, you will distinguish between user questions, permission issues, configuration errors, and technical faults.

Understand business processes: You will support users with workflows such as order processing, purchasing, sales, inventory management, and invoicing. You will identify relationships between documents, inventory, and postings.

Manage users and permissions: You will maintain user access, roles, and permissions according to agreed-upon approvals and assist with access issues.

Maintain Microsoft Cloud connections: You will provide support for user management, authentication, and the integration of ERP systems into Microsoft 365, Azure, and Microsoft Entra ID.

Support changes: You will participate in updates, tests, process improvements, and migration projects, and coordinate requirements with customers, departments, and development partners.

Share knowledge: You will create clear documentation and support users in utilizing their systems securely and efficiently.

What You Bring

Solid practical experience with Microsoft Dynamics NAV / Navision. Knowledge of older NAV versions, such as NAV 2016, is particularly important to us.

Very good knowledge of the Microsoft Cloud environment, especially Microsoft 365, Azure, and Microsoft Entra ID, with regard to user management, permissions, authentication, and application integration.

Willingness to work on-site in Cologne as well as occasional business travel to our customers.

Knowledge of AL for Business Central or C/AL for older NAV environments.
