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 energise 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 make it, store it, move it, sell it, and mend it.
As part of Centrica’s new transformation, you have an opportunity to play your part. Our Operational Technology keeps energy moving safely and reliably—and this role plays a vital part in protecting it. As an OT Analyst/Technician, you’ll provide hands‑on support across our OT cybersecurity and resilience activities, ensuring that industrial control systems remain secure, compliant and operationally robust.
You’ll work closely with engineers, cybersecurity specialists, and external partners to monitor OT environments, support incident response, maintain asset and patch records, and contribute to risk, compliance and audit activities. The role also supports the ongoing improvement of our OT controls, processes and tooling, making use of data‑driven and automated capabilities to streamline routine tasks and enhance the quality and speed of delivery.
This one goes both ways. It is a technically focused role with real operational impact, offering the opportunity to build deep OT expertise while contributing directly to the safe, secure and continuous delivery of energy to millions.
