OT Cyber Security Manager
We are seeking an experienced OT Cyber Security Manager to lead the protection of operational technology environments across critical industrial and infrastructure operations. This role will be responsible for developing and implementing a robust OT cyber security strategy, strengthening resilience, and ensuring that operational systems remain secure, reliable, and compliant with relevant standards and regulations. You will work closely with engineering, operations, IT, risk, compliance, and third-party partners to identify and manage cyber risks across industrial control systems, supervisory control and data acquisition environments, manufacturing systems, and connected operational assets.
Key responsibilities will include owning the OT security roadmap, policies, standards, and governance framework; conducting risk assessments and maturity reviews; overseeing vulnerability management, network segmentation, secure remote access, identity and access controls, asset visibility, monitoring, and incident response; and ensuring that security is embedded throughout the design, deployment, maintenance, and decommissioning of OT systems. You will also lead investigations into security events, coordinate remediation activities, support business continuity and recovery planning, and provide clear reporting on risk, performance, and compliance to senior stakeholders. The role will involve managing specialist suppliers and supporting security awareness and capability-building initiatives for operational teams.
The successful candidate will have substantial experience in OT, ICS, SCADA, industrial automation, or a closely related cyber security environment, together with a strong understanding of network architecture, industrial protocols, threat detection, vulnerability management, and cyber incident response. Experience applying standards and frameworks such as IEC 62443, NIST Cybersecurity Framework, ISO 27001, or the NIS regulations would be highly valued. A relevant professional qualification or degree is desirable, as are certifications such as GICSP, CISSP, CISM, or equivalent. You will be an effective communicator and pragmatic leader, able to influence stakeholders at all levels, balance security with operational requirements, and deliver improvements in complex, safety-critical environments.
