We are working with a leader in zero-waste energy to appoint an OT Assurance Consultant to strengthen their operational technology (OT) security assurance capability across programmes, projects, and steady-state operations. You will provide assurance to senior leadership on the design and operating effectiveness of OT security controls, supporting secure delivery in complex, safety-critical, regulated environments. This role focuses on embedding security early, applying sound judgement, and enabling delivery without compromising operational resilience.
Working closely with OT engineering, risk management, project managers, architects, business analysts, and operational support teams, you will help identify, assess, and mitigate OT cyber risks while ensuring safe and resilient plant operations.
Key responsibilities
- Define and assure OT security controls and functional/non-functional security requirements from the outset of projects (secure-by-design).
- Perform OT threat modelling and technical risk assessments, translating findings into actionable recommendations for design and delivery teams.
- Review OT architectures and designs (including industrial networks, segmentation models, and remote access) to identify control gaps and propose remediation/mitigation strategies.
- Validate implementation of OT security controls through: configuration reviews and hardening assessments, vulnerability scanning (where operationally safe), penetration testing coordination and assurance (including vendor-led testing).
- Support CAF-aligned assurance and compliance activities, providing evidence-based reporting and updates for OT systems and environments.
- Handle exceptions to security policy by developing risk treatment plans and proposing pragmatic compensating controls (especially for legacy systems, vendor constraints, and regulatory requirements).
- Coordinate and prioritise incoming OT assurance requests, working proactively with minimal oversight.
- Build strong working relationships with OT engineering, operations, project managers, and delivery teams to ensure security controls are practical, risk-based, and aligned to business outcomes.
- Resolve issues pragmatically, avoiding unnecessary escalations by offering clear options and mitigation strategies.
Qualifications
- Proven experience delivering OT / ICS cyber security assurance, ideally within Critical National Infrastructure (CNI) or safety-critical industrial environments.
- Strong understanding of the Cyber Assessment Framework (CAF), with experience supporting regulatory engagement and providing compliance updates for OT environments.
- Confident in OT-focused threat modelling, technical risk assessment, and security validation.
- Strong written and verbal communication skills, able to engage technical teams and senior non-technical stakeholders.
- Practical experience with recognised OT and cyber security standards and frameworks, including IEC 62443, NCSC Security Principles, NIST Cybersecurity Framework and ISO 27001 / ISO 27005.
- Comfortable coordinating workloads and interfacing with multi-disciplinary delivery teams (IT, OT, engineering, operations).
- Balanced, pragmatic approach to compliance and risk, aligned to operational constraints and plant realities.
