Technical Specialist - OT Security
We are seeking a Technical Specialist – OT Security to strengthen the protection, resilience and operational continuity of industrial control systems and other operational technology environments. In this role, you will support the development and implementation of security measures across production, manufacturing, utilities or other critical infrastructure settings. You will work closely with engineering, operations, IT, risk and compliance teams to identify vulnerabilities, reduce cyber risk and ensure that security controls are practical, proportionate and aligned with operational requirements.
Your responsibilities will include assessing OT networks, control systems and connected devices; supporting asset discovery, network segmentation, secure remote access and vulnerability management; and contributing to security monitoring, incident response and recovery activities. You will help maintain OT security standards, procedures, architecture principles and risk registers, while assisting with audits, threat assessments and compliance reviews. The role will also involve advising project teams on security requirements for new systems, reviewing technical designs, coordinating remediation plans and promoting secure-by-design practices throughout the operational technology lifecycle. Where required, you will participate in incident investigations, provide technical guidance during critical events and support continuous improvement initiatives.
The successful candidate will have experience in OT, industrial control systems, SCADA, automation or a closely related cybersecurity environment, together with a sound understanding of network security, system hardening, identity and access management, vulnerability assessment and security monitoring. Familiarity with standards and frameworks such as IEC 62443, NIST Cybersecurity Framework, ISO 27001 or similar is desirable. Relevant professional certifications in cybersecurity, networking or industrial automation would be advantageous. You should be analytical, collaborative and confident communicating technical risks to both specialist and non-specialist audiences. The ability to work methodically in safety-critical environments, manage competing priorities and occasionally support out-of-hours activities will be important.
