Senior OT Security Consultant
We are seeking a Senior OT Security Consultant to help protect critical operational technology environments across complex industrial and infrastructure settings. In this role, you will provide expert guidance on the security of control systems, industrial networks, supervisory control and data acquisition (SCADA) platforms, distributed control systems, and connected operational assets. You will work closely with engineering, operations, IT, risk, and compliance teams to identify security priorities and deliver practical, risk-based improvements without compromising safety, availability, or production requirements.
Your responsibilities will include conducting OT security assessments, maturity reviews, threat and risk assessments, vulnerability assessments, and gap analyses. You will develop and review security architectures, network segmentation strategies, secure remote-access solutions, monitoring and detection capabilities, incident response plans, and system hardening standards. You will support the creation and maintenance of policies, procedures, technical standards, and security roadmaps aligned with recognised frameworks and regulations, such as IEC 62443, NIST, ISO 27001, and relevant national critical-infrastructure requirements. You will also contribute to incident investigations, tabletop exercises, remediation planning, and the secure design of new OT projects and major system upgrades.
The successful candidate will have substantial experience in OT, industrial cybersecurity, control systems engineering, or a closely related field, together with a strong understanding of industrial protocols, OT network architectures, asset management, vulnerability management, and secure system design. Experience working in sectors such as energy, manufacturing, transport, utilities, or other regulated environments is highly desirable. Relevant professional certifications are advantageous. You will be confident engaging with both technical and non-technical stakeholders, able to translate complex security risks into clear business recommendations, and comfortable working independently on multiple consulting engagements. Strong analytical, communication, report-writing, and client-management skills are essential, along with a pragmatic approach to improving security in environments where operational continuity and safety are paramount.
