Senior OT Cyber Security Engineer

We're looking for a Senior OT Cyber Security Engineer to help shape the future of cyber resilience across a major critical-infrastructure organisation. This is an opportunity to join a highly skilled global cyber security function, playing a key role in protecting essential operational technology and supporting the secure delivery of reliable electricity to millions of customers. What you'll be doing In this role, you'll design and implement secure network solutions, embed security throughout the application and infrastructure lifecycle, and ensure continuous monitoring across complex OT environments. You'll contribute technical leadership to identity and access management design, assess the effectiveness of security controls, and integrate robust security measures into CI/CD pipelines. Your work will directly support a major cyber transformation programme, helping the organisation stay ahead of emerging threats and regulatory demands. Reporting to the Cyber Architecture Lead, you'll collaborate across technical and operational teams, supporting long-term planning and contributing to a 12-month delivery roadmap. Relevant industry certifications are welcome, and the role offers the chance to work internationally while shaping the organisation's future security posture.
