qtlabs - Quantum Technology Laboratories GmbH

Security Engineer

• Operate and secure an ICT system with strict separation of network domains ("red-black separation").
• Design, implement, and monitor security-relevant network controls such as firewalls, VLANs, gateways, filtering mechanisms, and data-diode-based transmission paths.
• Perform security monitoring, log analysis, system hardening, and regular audits to ensure compliance.
• Manage user and access control concepts, implementing least-privilege and zero-trust principles.
• Operate and maintain local server environments (physical and virtual).
• Administer and monitor central services such as: NAS systems (storage, backups, snapshots, quotas), internal Git and GitLab instances, authentication and directory services, and internal communication and collaboration systems.
• Plan and execute updates, patches, security checks, and system optimizations.
• Automate recurring tasks using scripting languages (e.g., Bash, Python, PowerShell).
• Ensure reliable 24/7 operation of infrastructure components (including participation in an on-call rotation).
• Create and maintain technical documentation, runbooks, and security concepts.
• Provide user support in a strictly regulated IT environment.
