Operational Technology (OT) Cyber Security Engineer
We are seeking an Operational Technology (OT) Cyber Security Engineer to help protect industrial control systems, operational networks and connected technologies across critical environments. In this role, you will work with engineering, infrastructure, operations and risk teams to strengthen cyber resilience while supporting safe, reliable and compliant business operations. You will assess OT environments, identify vulnerabilities and security gaps, and develop practical measures that reduce risk without disrupting operational continuity.
Your responsibilities will include designing and maintaining OT security controls; monitoring and investigating security events; supporting incident response and recovery activities; and contributing to vulnerability management, patching and secure configuration programmes. You will help define and enforce network segmentation, access control, secure remote connectivity, endpoint protection and asset-management practices. The role will also involve conducting risk assessments, reviewing system architectures, supporting security testing, maintaining technical documentation and contributing to policies, standards and cyber improvement roadmaps. You will provide guidance on the secure design and implementation of new OT systems, technologies and integrations, including industrial IoT and cloud-connected platforms.
Applicants should have proven experience in OT, industrial control systems, SCADA, PLC or related operational environments, together with a strong understanding of industrial networking, common cyber threats and recognised security frameworks such as IEC 62443, NIST or ISO 27001. Experience with security monitoring tools, vulnerability assessment, incident management and network technologies is desirable. Relevant professional certifications in cyber security, networking or industrial security would be advantageous. You will need strong analytical and communication skills, the ability to engage effectively with both technical and non-technical stakeholders, and a practical, risk-based approach to problem solving. The successful candidate will be organised, collaborative and comfortable working in environments where safety, availability and security are equally important.
