Maintain and support Linux servers, virtual machines, Docker environments, and internal services.
Plan and perform operating system upgrades, security updates, patching, hardening, and lifecycle management.
Monitor infrastructure health, capacity, availability, backups, performance, and security vulnerabilities.
Establish reliable backup, restore, disaster-recovery, and business-continuity procedures.

Provide advanced technical support and act as the escalation point for complex infrastructure and access issues.
Document systems, dependencies, maintenance procedures, architecture decisions, and recovery processes.
Coordinate with vendors and external service providers where required.

Must-haves (to thrive in this role)

Experience & education

Several years of experience in IT infrastructure, systems administration, cloud engineering, or IT operations.
A degree in computer science or a related field, or an equivalent qualification.

Azure & cloud migration

Hands-on experience with Microsoft Azure, especially Azure VMs, networking, storage, monitoring, backup, Entra ID, RBAC, and security controls.
Experience planning or executing cloud and infrastructure migrations.

You can work on site at one of our offices in Ilmenau, Erfurt or Leipzig, especially during your first months.
