Join us, be part of more. We’re so much more than an energy company. We’re a family of brands revolutionising how we power the planet. We're energisers. One team of 21,000 colleagues that's energising a greener, fairer future by creating an energy system that doesn’t rely on fossil fuels, whilst living our powerful commitment to igniting positive change in our communities.
Here, you can find more purpose, more passion, and more potential. That’s why working here is #MoreThanACareer.
We do energy differently - we do it all. We make it, store it, move it, sell it, and mend it.
As part of the new transformation, an opportunity to play your part - Operational Technology is the core of how we generate, store and deliver energy - and the OT Lead / Engineer plays a pivotal role in protecting that core. You’ll safeguard the industrial systems that keep our sites running, leading OT incident response, strengthening cyber defences, and ensuring our control environments remain resilient, compliant and ready for tomorrow’s challenges.
This is a hands-on, high-impact role where you’ll drive security operations, influence strategic decisions, and shape the future of secure energy infrastructure across Centrica Power’s portfolio, and you’ll embrace opportunities to use automation and data-enabled tools to improve the efficiency and effectiveness of security operations.
Day to day
- Monitor and manage OT cybersecurity incidents, working with CSIRT and GSOC to investigate events, assess impact, and coordinate containment and remediation actions.
- Oversee the day-to-day operation of OT cybersecurity controls, ensuring effective monitoring, patching, backups, recovery validation, and secure remote access across Power sites.
- Maintain OT risk and compliance activities, including risk assessments, control validation, asset inventory updates, and support for regulatory and internal assurance requirements.
- Plan and support testing activities such as penetration tests, resilience and failover testing, and security validation during commissioning and operational handover.
- Manage OT security changes across the asset lifecycle, including configuration baselines, obsolescence reviews, technology refresh planning, and change control.
- Support projects and suppliers by providing OT security input to designs, reviewing vendor solutions and contractual security requirements, and identifying continuous improvements to strengthen OT security and resilience.
