• Contribute to the rollout, operation, and continuous improvement of the MDM/UEM solution as it is introduced and expanded.
• Assist in monitoring and responding to security alerts, performing initial analysis and escalating incidents to the Head of IT Security & Compliance.
• Help implement and maintain security hardening guidelines for endpoints, user accounts, and collaboration platforms.

• Pragmatic approach to risk management, balancing security needs with operational efficiency.
• Exposure to MDM/UEM solutions (such as Microsoft Intune) and a willingness to actively contribute to their rollout and optimization.
• Previous involvement in IT or security projects such as tool deployments, migrations, or process improvements.
• Strong problem-solving skills with a methodical and independent approach to troubleshooting.
• Ability to manage multiple tasks and requests simultaneously, prioritizing effectively in a fast-growing environment.

• You are looking for a large, highly structured corporate environment with strict separation between IT and security responsibilities.
• You are uncomfortable providing end-user support and engaging directly with employees on a regular basis.
• You want to work fully remotely without regular on-site presence; this role requires hands-on access to devices and office infrastructure.
• You prefer working strictly from predefined procedures and are not interested in helping design, improve, or document processes.
