Job Search

We are seeking an Operational Technology (OT) Cyber Security Engineer to help protect industrial control systems, supervisory control and data acquisition (SCADA) environments, and other critical operational technology platforms. You will work across engineering, infrastructure, operations and risk teams to strengthen the security and resilience of systems that support essential processes. This role offers the opportunity to contribute to practical, risk-based cyber security improvements in complex and highly regulated environments.

Your responsibilities will include assessing OT networks, systems and processes against recognised security frameworks and internal standards; identifying vulnerabilities and recommending appropriate remediation; supporting secure architecture, segmentation and access-control designs; and maintaining accurate asset inventories, network diagrams, risk registers and security documentation. You will contribute to security monitoring, incident response, threat analysis and investigation, helping to coordinate containment and recovery activities where required. You will also support vulnerability management, patching and configuration reviews while taking account of operational availability, safety and change-control requirements.

The successful candidate will have experience in OT, industrial control systems, SCADA, distributed control systems or a closely related cyber security environment. Knowledge of protocols such as Modbus, DNP3, OPC, Ethernet/IP or IEC 61850, together with an understanding of Purdue-style architectures and industrial networking, would be highly beneficial. Experience with security standards and guidance such as IEC 62443, NIST Cybersecurity Framework, ISO 27001 or NIS2 is desirable. You should be comfortable working with technical and non-technical stakeholders, producing clear reports and influencing improvements across multiple teams. Relevant professional certifications in cyber security, networking, industrial automation or risk management are advantageous. A methodical approach, strong communication skills and a commitment to safe, reliable operations are essential.

We are seeking an Operational Technology (OT) Cyber Security Engineer to help protect industrial control systems, operational networks and connected technologies across critical environments. In this role, you will work with engineering, infrastructure, operations and risk teams to strengthen cyber resilience while supporting safe, reliable and compliant business operations. You will assess OT environments, identify vulnerabilities and security gaps, and develop practical measures that reduce risk without disrupting operational continuity.

Your responsibilities will include designing and maintaining OT security controls; monitoring and investigating security events; supporting incident response and recovery activities; and contributing to vulnerability management, patching and secure configuration programmes. You will help define and enforce network segmentation, access control, secure remote connectivity, endpoint protection and asset-management practices. The role will also involve conducting risk assessments, reviewing system architectures, supporting security testing, maintaining technical documentation and contributing to policies, standards and cyber improvement roadmaps. You will provide guidance on the secure design and implementation of new OT systems, technologies and integrations, including industrial IoT and cloud-connected platforms.

Applicants should have proven experience in OT, industrial control systems, SCADA, PLC or related operational environments, together with a strong understanding of industrial networking, common cyber threats and recognised security frameworks such as IEC 62443, NIST or ISO 27001. Experience with security monitoring tools, vulnerability assessment, incident management and network technologies is desirable. Relevant professional certifications in cyber security, networking or industrial security would be advantageous. You will need strong analytical and communication skills, the ability to engage effectively with both technical and non-technical stakeholders, and a practical, risk-based approach to problem solving. The successful candidate will be organised, collaborative and comfortable working in environments where safety, availability and security are equally important.

We are seeking an Operational Technology (OT) Cyber Security Engineer to help protect industrial control systems, operational networks and critical infrastructure from evolving cyber threats. Working across engineering, technology, operations and risk teams, you will support the design, implementation and continuous improvement of OT security controls while maintaining the safety, reliability and availability of operational environments.

Your responsibilities will include assessing OT architectures, networks and control systems; identifying vulnerabilities and cyber risks; and developing practical remediation plans that reflect operational constraints. You will contribute to network segmentation, secure remote access, identity and access management, endpoint protection, vulnerability management, security monitoring and incident response across OT environments. You will also support security assessments, technical reviews, risk evaluations and change activities, ensuring that proposed solutions are proportionate and do not adversely affect production or safety. The role will involve maintaining security documentation, standards, procedures and asset inventories, as well as producing clear reports for technical and non-technical stakeholders. You may also assist with investigations, threat intelligence reviews, audit activities and the development of OT cyber security awareness and training.

Applicants should have experience in OT, industrial control systems, SCADA, PLC, DCS or similar operational environments, together with a strong understanding of industrial networking protocols and technologies. Knowledge of recognised cyber security frameworks and standards, such as IEC 62443, NIST or ISO 27001, is desirable. You will need practical experience with security monitoring, vulnerability assessment, risk management and incident response, along with the ability to work collaboratively in complex, safety-conscious settings. Relevant qualifications in cyber security, information technology, engineering or a related discipline are advantageous, as are professional certifications. Strong analytical, communication and problem-solving skills are essential, alongside a willingness to work with stakeholders at all levels and, where required, support site visits or out-of-hours incident response.
