Cyber Security Advisory Lead - ICS/SCADA/OT
We are seeking an experienced Cyber Security Advisory Lead specialising in Industrial Control Systems (ICS), Supervisory Control and Data Acquisition (SCADA), and Operational Technology (OT). This role will provide strategic and practical security advice to organisations operating critical infrastructure, industrial environments, and connected operational networks. You will lead advisory engagements, assess cyber risk across OT environments, and develop effective, risk-based security strategies that balance operational resilience, safety, availability, and regulatory obligations.
Key responsibilities will include leading OT and ICS security assessments, maturity reviews, threat and risk assessments, architecture reviews, and gap analyses. You will advise clients on secure network design, segmentation, remote access, asset visibility, vulnerability management, incident response, monitoring, identity and access management, and third-party risk. You will also develop security roadmaps, policies, standards, procedures, and technical recommendations, while supporting the implementation of recognised frameworks and regulations such as IEC 62443, NIST, NIS2, and relevant national critical infrastructure requirements. The role will involve presenting findings to senior stakeholders, facilitating workshops, mentoring consultants, contributing to proposals, and helping shape new advisory services.
The successful candidate will have substantial experience in OT, ICS, SCADA, or industrial cyber security, gained within consulting, engineering, utilities, manufacturing, energy, transport, or another critical infrastructure environment. Strong knowledge of industrial protocols, control system architectures, OT threat landscapes, and secure-by-design principles is essential. Experience engaging with both technical and executive audiences, managing client-facing projects, and translating complex risks into clear business recommendations is highly valued. Relevant certifications such as GICSP, GRID, CISSP, CISM, ISA/IEC 62443, or equivalent would be advantageous. You should be commercially aware, analytical, collaborative, and confident working across multidisciplinary teams. Occasional travel may be required, and eligibility for relevant background screening will be expected.
