OT Security Consultant
We are seeking an OT Security Consultant to help protect industrial control systems, operational technology environments and critical infrastructure from evolving cyber threats. In this role, you will work with engineering, IT, operations and risk teams to assess security maturity, identify vulnerabilities and develop practical improvements that support both safety and operational continuity. You will contribute across the full security lifecycle, from discovery and risk assessment through to implementation, validation and ongoing improvement.
Your responsibilities will include conducting OT and ICS security assessments, reviewing network architecture, analysing asset inventories and evaluating controls against recognised frameworks and standards such as IEC 62443, NIST and ISO 27001. You will help design secure network segmentation, remote access, monitoring and incident response capabilities, while supporting the development of policies, procedures and recovery plans. You will also provide guidance on vulnerability management, threat modelling, configuration reviews, third-party risk and secure system commissioning. The role may involve site visits, workshops and collaboration with suppliers, system integrators and internal stakeholders.
Applicants should have proven experience in OT, ICS, SCADA or industrial cybersecurity, with a solid understanding of industrial protocols, control-system architectures and the differences between IT and operational environments. Experience with risk assessments, security tools, network analysis, incident response or compliance programmes is highly desirable. Relevant professional certifications in cybersecurity, industrial security or risk management are advantageous. Strong communication and consulting skills are essential, as you will need to explain technical risks clearly, produce high-quality reports and influence stakeholders at different levels. A pragmatic, methodical approach, willingness to learn and the ability to balance security requirements with operational realities will be key to success.
