Technical Specialist - OT Security
We are seeking a Technical Specialist – OT Security to help protect operational technology environments that support critical industrial processes and infrastructure. In this role, you will contribute to the design, implementation and continuous improvement of security controls across OT networks, industrial control systems, supervisory control and data acquisition (SCADA) platforms, and connected operational assets. You will work closely with engineering, infrastructure, operations, risk and compliance teams to strengthen resilience while maintaining safety, availability and operational continuity.
Your responsibilities will include assessing OT environments and identifying vulnerabilities, threats and security gaps; supporting the development and maintenance of OT security architecture, standards, policies and procedures; and implementing appropriate monitoring, segmentation, access control, vulnerability management and incident response capabilities. You will participate in security assessments, risk analyses, audits and improvement programmes, as well as help investigate and respond to security incidents affecting operational systems. The role will also involve maintaining asset inventories, reviewing technical changes, supporting secure remote access, and ensuring that security requirements are incorporated into projects and lifecycle management processes. You may also contribute to awareness activities, playbooks, testing exercises and the evaluation of new security technologies.
The successful candidate will have demonstrable experience in OT, ICS, SCADA or industrial cybersecurity, together with a sound understanding of network security principles, industrial protocols, system hardening, identity and access management, and security monitoring. Experience with standards and frameworks such as IEC 62443, NIST Cybersecurity Framework, NIST SP 800-82 or ISO 27001 is highly desirable. Relevant certifications in cybersecurity, industrial control systems or risk management would be advantageous. You should be analytical, collaborative and comfortable communicating technical risks to both specialist and non-specialist audiences. The ability to work methodically in complex environments, manage competing priorities and occasionally support activities outside standard business hours is also important.
