OT Security Engineer
We are seeking an OT Security Engineer to strengthen the security and resilience of operational technology environments across critical industrial and infrastructure operations. In this role, you will help protect industrial control systems, supervisory control and data acquisition (SCADA) platforms, distributed control systems, plant networks, and connected operational assets. You will work closely with engineering, operations, IT, and risk teams to identify threats, reduce vulnerabilities, and support secure, reliable production.
Your responsibilities will include conducting OT security assessments, analysing network architecture and traffic, maintaining asset inventories, and identifying vulnerabilities across industrial environments. You will develop and implement appropriate security controls, including network segmentation, secure remote access, access management, endpoint protection, monitoring, and configuration standards. You will support incident detection and response, investigate security events, contribute to root-cause analysis, and help coordinate recovery activities while minimising operational disruption. The role will also involve creating and maintaining security policies, procedures, risk assessments, technical documentation, and compliance evidence. You may contribute to security-by-design reviews for new systems, upgrades, and engineering projects, as well as supplier and third-party risk assessments.
Applicants should have practical experience in OT, ICS, SCADA, industrial networking, or a closely related security engineering environment. A strong understanding of industrial protocols such as Modbus, DNP3, OPC, or IEC 61850, together with knowledge of TCP/IP networking, firewalls, vulnerability management, and security monitoring, is highly desirable. Familiarity with recognised standards and frameworks such as IEC 62443, NIST Cybersecurity Framework, NIST SP 800-82, or ISO 27001 would be advantageous. Relevant professional certifications in cybersecurity, networking, or industrial control systems are welcome. You should be analytical, methodical, and confident communicating technical risks to both specialist and non-specialist audiences. The ability to work collaboratively, manage competing priorities, and occasionally support planned maintenance or incident response outside normal hours will be important.
