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. We have an exciting opportunity for a Data Scientist to join our team, using relevant data to tackle complex business challenges and turn insight into measurable outcomes. You'll work across a varied portfolio of customer, commercial and operational problems, from understanding churn and retention to Customer Lifetime Value (CLTV), segmentation, propensity modelling and operational optimisation. This is more than a model-development role. You'll have the opportunity to build reusable, production-ready solutions, embed models into business processes and see the real-world impact of your work.

Location: We operate a Flexible First approach, giving colleagues flexibility in how and where they work. This role can be predominantly home-based, although ideally you will be based within commutable distance of our Cardiff site and be flexible to travel across our sites as may be needed on occasion for team meetings.

That's why we've designed our total rewards to give you the flexibility to choose what you need, when you need it, making sure that you and your family are supported not only financially, but physically and emotionally too.
