Security Operations

• Build and defend the IT backbone of a growing deep-tech scale-up
• Design, implement, operate and continuously improve the IT and security backbone of a fast-growing, security-critical organization
• Lead a small internal IT team and ensure that operational IT, security requirements and business priorities are aligned
• Report directly to management and work closely with our external CISO and other technical leaders
• Accountable for a reliable, secure cloud-first IT environment with only necessary on-prem components
• Clear IT governance, processes and enforceable standards
• Ensuring that security policies and governance requirements (e.g. ISMS) are understood, implemented and lived across the organization
• Translating CISO-defined security and compliance requirements into practical operational implementation within IT
• Prioritization, workload management and operational excellence under limited resources
• IT budget ownership (planning, prioritization, cost control, supplier management)
• A pragmatic mid-term roadmap aligned with growth, risk and compliance needs

Head of IT & Security Operations

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.
