We are seeking a Technical Specialist – OT Security to help protect operational technology environments that support critical industrial processes. In this role, you will contribute to the design, implementation and continuous improvement of cybersecurity measures across industrial control systems, supervisory control and data acquisition (SCADA) platforms, networks and connected operational assets. You will work closely with engineering, infrastructure, operations and risk teams to identify security weaknesses, reduce exposure and maintain safe, reliable operations.
Your responsibilities will include conducting OT security assessments, supporting vulnerability management and coordinating remediation activities in environments where availability and safety are essential. You will assist with security architecture reviews, network segmentation, access control, monitoring, incident response and the development of practical security standards and procedures. The role will also involve maintaining asset inventories, reviewing technical changes, contributing to risk assessments and supporting compliance with relevant industrial cybersecurity frameworks and regulations. You may participate in investigations of security events, provide guidance during projects and help raise security awareness among technical and operational stakeholders.
The successful candidate will have experience in OT, industrial control systems, automation, network security or a closely related field, together with a good understanding of protocols, technologies and architectures used in industrial environments. Familiarity with recognised standards such as IEC 62443, NIST or ISO 27001 is highly desirable. You should be comfortable analysing technical risks, documenting findings and communicating recommendations to both specialist and non-specialist audiences. Experience with security monitoring tools, vulnerability assessment, firewall administration, incident handling or secure remote access would be advantageous. A methodical approach, strong collaboration skills and the ability to work independently in complex operational environments are essential.
