Senior Operational Technology (OT) Security Consultant

Reference: p0hlpj6rh04yzqc2dffn

We are seeking a Senior Operational Technology (OT) Security Consultant to provide expert guidance on protecting industrial control systems, critical infrastructure, and connected operational environments. You will work with clients and internal stakeholders to assess OT security maturity, identify vulnerabilities, define improvement roadmaps, and support the implementation of effective security controls. The role requires a strong understanding of the differences between IT and OT environments, including the importance of safety, availability, reliability, and operational continuity.

Your responsibilities will include leading OT security assessments, risk and threat analyses, architecture reviews, and site-based evaluations. You will develop and review policies, standards, procedures, network segmentation strategies, secure remote access solutions, incident response plans, and resilience frameworks. You will also advise on industrial protocols, asset discovery, vulnerability management, security monitoring, identity and access management, endpoint protection, and the secure design of control systems. Where required, you will support incident investigations, remediation planning, audit activities, regulatory alignment, and the delivery of security improvement programmes. You will present findings and recommendations clearly to both technical and executive audiences, while mentoring less experienced consultants and contributing to the development of methodologies, proposals, and client deliverables.

The successful candidate will have substantial experience in OT, ICS, SCADA, automation, or industrial cybersecurity, supported by a strong background in security consulting, risk management, or operational resilience. Experience with recognised frameworks and standards such as IEC 62443, NIST CSF, NIST SP 800-82, ISO 27001, or similar is highly desirable. Relevant professional certifications, such as CISSP, CISM, GICSP, GRID, or IEC 62443 qualifications, would be advantageous. You should be confident working independently and collaboratively, possess excellent communication and report-writing skills, and be comfortable engaging with engineers, plant operators, security teams, and senior decision-makers. A willingness to travel to operational sites may be required.
