YOUR ROLE
- OT Network Architecture: You design and implement secure network architectures for industrial IT/OT environments based on established models such as the Purdue Reference Model or Zero Trust approaches for OT.
- Segmentation & Zone-Conduit Concepts: You develop segmentation concepts according to IEC 62443 and implement them using firewalls, IDMZ architectures, VLANs, and Network Access Control in real production environments.
- OT Security & Network Assessments: You evaluate existing OT network topologies, firewall rules, and remote access solutions regarding vulnerabilities, segmentation gaps, and regulatory requirements from CRA, NIS2, and IEC 62443.
- Blueprint Development: You create referenceable OT network and security blueprints, including standard switch/firewall designs, IDMZ concepts, and principles for secure machine integration and remote maintenance.
- Monitoring & Anomaly Detection: You conceptualize and integrate solutions for OT network monitoring, IDS/IPS, and SIEM in industrial control environments and support the establishment of OT SOC-capable operations.
- Independent Work: Our flat hierarchies quickly give you the freedom to shape things yourself and take responsibility for the network and security architecture of our industrial clients.
YOUR PROFILE
- Network Expertise: You have sound knowledge in routing and switching (VLAN, BGP, OSPF), firewall technologies, VPN, and NAC with a relevant degree and at least 5 years of practical experience in industrial network infrastructures.
- OT Technology Understanding: You are familiar with industrial control systems (PLC, SCADA, DCS) as well as common industrial protocols like Modbus, Profinet, OPC UA, and MQTT, and understand their specific security and network requirements.
- Segmentation Concepts: You are familiar with the planning and implementation of network segmentation in OT environments, from zone formation at the cell level to secure connection to the corporate IT and cloud or edge systems.
- Security Frameworks & Regulations: You are familiar with IEC 62443, NIST SP 800-82, NIS2, and CRA, and can translate their requirements into concrete network and security measures.
- Tool Knowledge: You have practical experience with tools for asset discovery, vulnerability management, OT network monitoring, and SIEM solutions, and can use and evaluate them effectively in industrial environments.
- Language Skills: Your very good German and English skills enable you to communicate effectively with IT/OT managers and client management.
