Principal OT Cybersecurity Consultant
We are seeking a Principal OT Cybersecurity Consultant to lead the delivery of cybersecurity advisory and assurance services across operational technology environments. You will work with senior stakeholders, engineering teams, site personnel, and technology partners to improve the security, resilience, and compliance of industrial control systems and critical infrastructure. This role requires a strong understanding of the differences between IT and OT security, including the need to protect safety, availability, reliability, and operational continuity.
Your responsibilities will include assessing OT environments, identifying cyber risks and vulnerabilities, and developing practical remediation strategies that can be implemented without disrupting essential operations. You will lead security architecture reviews, maturity assessments, threat and risk assessments, network segmentation initiatives, incident response planning, and the development of OT security standards, policies, and procedures. You will also support regulatory and assurance activities, contribute to security-by-design across new projects, and provide expert guidance on monitoring, access control, asset management, vulnerability management, and secure remote connectivity. As a principal-level consultant, you will mentor colleagues, review technical deliverables, manage stakeholder relationships, and contribute to the continuous improvement of consulting methods and service offerings.
Applicants should have substantial experience in OT, ICS, SCADA, or industrial cybersecurity, together with a proven record of delivering consulting or transformation programmes in complex environments. Strong knowledge of recognised frameworks and standards such as IEC 62443, NIST Cybersecurity Framework, NIST SP 800-82, ISO 27001, or relevant regulatory requirements is expected. Experience with industrial networking, control systems, engineering practices, and cyber risk management is highly desirable. Professional certifications such as CISSP, CISM, GIAC, GICSP, or IEC 62443 are advantageous. Excellent communication, analytical, and influencing skills are essential, along with the ability to translate technical risk into clear business decisions and practical, risk-based outcomes.
