Senior OT Cyber Engineer
We are seeking a Senior OT Cyber Engineer to lead the protection, resilience and continuous improvement of operational technology environments across critical industrial and infrastructure operations. You will work at the intersection of cybersecurity, engineering and operations, helping to secure industrial control systems, supervisory control and data acquisition (SCADA) platforms, distributed control systems, plant networks and connected operational assets. The role requires a practical understanding of the safety, availability and performance requirements that distinguish OT environments from traditional IT systems.
Your responsibilities will include designing and implementing OT cybersecurity architectures, network segmentation and secure remote-access solutions; conducting risk assessments, vulnerability reviews and security maturity evaluations; and developing and maintaining standards, procedures and technical controls aligned with recognised frameworks such as IEC 62443, NIST and ISO 27001. You will support incident detection and response, threat modelling, security monitoring, patch and change management, backup and recovery planning, and the secure introduction of new technologies. You will also investigate security events, coordinate remediation activities and provide clear technical recommendations to engineering, operations, IT and leadership teams. Where appropriate, you will contribute to audits, assurance activities, disaster-recovery exercises and the development of cybersecurity improvement programmes.
The successful candidate will have substantial experience in OT, ICS or industrial cybersecurity, together with strong knowledge of network protocols, firewalls, intrusion detection, endpoint protection, identity management and security monitoring. Experience with platforms such as PLCs, HMIs, historians, engineering workstations and industrial communications is highly desirable. You should be confident working in complex, regulated or safety-critical environments and able to translate technical risks into practical business actions. Relevant professional certifications or formal training in cybersecurity, networking, control systems or engineering are advantageous. Strong communication, stakeholder-management and problem-solving skills are essential, along with the ability to work independently, influence decision-making and support colleagues in building a resilient security culture.
