Senior IS Business Analyst in Windsor

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 energises a greener, fairer future by creating an energy system that doesn’t rely on fossil fuels, while living our commitment to igniting positive change in our communities. 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. Centrica Technology is a core driver of our strategy. You’ll join a team modernising our platforms, strengthening cyber and operational resilience, and advancing a product‑led way of working that brings engineers, data specialists and business experts together to deliver meaningful outcomes at pace.

We are scaling automation and AI from proof of concept into real, end‑to‑end change – improving customer journeys, reducing cost to serve, accelerating delivery, and building the digital foundations that underpin everything from energy trading and risk to field operations and critical infrastructure. If you want to work on complex, high‑impact problems using modern engineering practices, and help build reusable platforms that will shape how Centrica operates over the next decade, this is the place to do it.

As a Senior Business Analyst within Centrica Technology, you’ll play a key role in shaping and delivering large, complex transformation initiatives that drive real business value. Working across the full lifecycle—from early shaping through to delivery—you’ll define high‑quality functional and non‑functional requirements that bridge business ambition and technology execution. You’ll collaborate closely with stakeholders across Group Functions and Technology to turn strategic objectives into clear, actionable solutions.
