Technical Specialist - OT Security
We are seeking a Technical Specialist – OT Security to help protect industrial control systems, operational technology environments, and critical infrastructure against evolving cyber threats. In this role, you will provide specialist expertise across the design, implementation, monitoring, and continuous improvement of OT security controls. You will work closely with engineering, operations, IT, risk, and compliance teams to ensure that security measures support safe, reliable, and efficient business operations.
Your responsibilities will include conducting OT security assessments, identifying vulnerabilities and risks, and developing practical remediation plans. You will support the implementation of network segmentation, secure remote access, asset discovery, identity and access management, endpoint protection, logging, monitoring, and incident response capabilities. You will contribute to security architecture and design reviews for control systems, industrial networks, and new technology deployments. The role will also involve maintaining security standards, procedures, risk registers, and technical documentation, as well as supporting audits, regulatory compliance, and third-party security reviews.
The successful candidate will have experience in OT, industrial control systems, SCADA, automation, or industrial networking, together with a strong understanding of cybersecurity principles and risk management. Knowledge of recognised OT security frameworks and standards, such as IEC 62443, NIST, or ISO 27001, is highly desirable. You should be comfortable working across both technical and operational environments, communicating clearly with stakeholders at all levels, and translating complex security risks into practical actions. Experience with vulnerability management, threat detection, incident response, or security monitoring in an industrial setting would be advantageous. A proactive approach, strong analytical skills, and the ability to work independently while contributing effectively to multidisciplinary teams are essential.
