OT Cyber Security Lead
We are seeking an experienced OT Cyber Security Lead to develop and strengthen the cyber security strategy for operational technology environments. You will provide leadership across industrial control systems, manufacturing technology, critical infrastructure, and connected operational platforms, ensuring that security is integrated into the design, operation, and improvement of OT services. Working closely with engineering, infrastructure, risk, compliance, and site-based teams, you will help protect the availability, safety, integrity, and confidentiality of operational systems.
Your responsibilities will include defining and maintaining OT security policies, standards, architectures, and procedures; assessing cyber risks across OT environments; and developing practical controls that reflect operational requirements. You will lead vulnerability management, threat modelling, security monitoring, incident response, and recovery planning for industrial systems. The role will also involve overseeing security assessments, penetration testing, supplier assurance, network segmentation, remote access controls, identity management, endpoint protection, and secure change management. You will support the investigation of security incidents, coordinate remediation activity, and provide clear reporting on risk, compliance, and performance to senior stakeholders.
You will bring substantial experience in OT, ICS, SCADA, industrial networks, or a closely related cyber security discipline, together with a strong understanding of recognised frameworks and standards such as IEC 62443, NIST, ISO 27001, or the NIS2 requirements. Experience of working in safety-critical or highly regulated environments is highly desirable. Strong knowledge of networking, asset discovery, vulnerability assessment, security operations, and incident management is expected, along with the ability to translate complex technical risks into practical business recommendations. Relevant professional certifications and demonstrable experience leading cross-functional programmes would be advantageous. Excellent communication, influencing, analytical, and problem-solving skills are essential.
