About the project

We are looking for a Microsoft 365 Implementation & Migration Engineer to support a large-scale Microsoft 365 transformation for one of the leading cinema operators in Germany, with operations across several European markets.

The project focuses on transitioning from legacy IT infrastructure to a modern, secure, cloud-based digital workplace. The transformation is structured into two phases.

The first phase involves establishing a secure Microsoft 365 environment, implementing identity and access management, deploying endpoint management solutions, and migrating core collaboration and communication services to the cloud. This includes Microsoft Entra ID, Microsoft Intune, Exchange Online, Microsoft Teams, SharePoint Online, OneDrive, and Microsoft 365 Apps.

The second phase focuses on enabling advanced Microsoft 365 capabilities, including Microsoft 365 Copilot, workflow automation with Power Automate, and data analytics with Power BI.

The role will involve hands-on technical implementation, migration, configuration, security hardening, and troubleshooting. You will contribute to delivering a consistent and secure digital workplace for headquarters and distributed cinema locations across multiple countries.
