We are seeking an OT Security Officer to help protect operational technology environments that support critical industrial and business processes. In this role, you will develop, implement and maintain security measures across industrial control systems, supervisory control and data acquisition platforms, network infrastructure and connected operational assets. You will work closely with engineering, infrastructure, operations, risk and compliance teams to ensure that security is embedded throughout the lifecycle of OT systems, from design and deployment through maintenance and decommissioning.

Your responsibilities will include identifying and assessing cyber risks, maintaining OT asset inventories, reviewing network architecture and access controls, and supporting the implementation of secure segmentation and monitoring capabilities. You will contribute to vulnerability management, security assessments, incident response planning and investigations, while recognising the operational and safety requirements of industrial environments. The role will also involve developing and maintaining security policies, procedures, standards and technical documentation; coordinating patching and remediation activities; supporting audits; and providing clear reports and recommendations to technical and senior stakeholders. You may also help deliver security awareness and specialist guidance to personnel working with OT systems.

The successful candidate will have experience in OT, ICS, SCADA, industrial networking or a closely related cybersecurity environment, together with a sound understanding of cybersecurity principles, threat management and secure system design. Familiarity with recognised OT security frameworks and standards, such as IEC 62443, NIST or ISO 27001, is desirable. You should be analytical, organised and able to communicate effectively with both technical and non-technical audiences. Experience of incident response, risk assessment, vulnerability management, network monitoring or security tooling will be advantageous. Relevant professional qualifications or certifications are welcomed, as is a practical understanding of safety-critical operations, change control and the challenges of securing legacy technology.
