• Design, develop and embed OT cyber assurance frameworks, translating strategic security objectives into structured assurance programmes.
• Plan and deliver cyber assurance activities, including stakeholder interviews, workshops, documentation reviews, security assessments and technical audits.
• Assess the effectiveness of existing cyber security controls across OT environments, identifying control gaps, vulnerabilities and opportunities for improvement.
• Evaluate OT security arrangements against recognised cyber security standards and frameworks, including NCSC Cyber Assessment Framework (CAF), IEC 62443 and NIST.
• Undertake evidence gathering and control validation, ensuring assurance findings are supported by clear and appropriate documentation.
• Identify and assess cyber security risks across operational systems and infrastructure, providing practical, risk-based recommendations and supporting mitigation planning.
• Produce clear, actionable assurance reports, communicating technical findings, risks and recommendations to both technical and non-technical audiences.
• Work closely with OT engineers, asset owners, cyber security specialists and operational teams to understand existing environments and facilitate assurance activities.
• Provide subject matter expertise on OT cyber security threats, vulnerabilities, attack vectors and appropriate compensating controls.
• Present assurance findings, recommendations and progress updates to stakeholders and senior management.
• Contribute to the continuous improvement of cyber assurance methodologies, governance processes and ways of working.
