The Customer Entities team sits at the centre of the the company Customer system; providing the foundations for the customer's experience.

You will be helping with further enhancing the relatively new addresses product with features such as verifying address information.

What you'll do:

We have lots of difficult design challenges to solve. The UK utilities market is complicated, outdated and process-heavy - there's an awful lot of domain modelling that we need to get right. Strong attention to detail is essential.

• We have challenging technical problems to solve; like processing tens of millions of meter readings a day. We need the right technology in place to handle this smoothly as well as feeding data into a machine learning pipeline that models and predicts consumption. Or thinking about how we adapt the company to improve other utilities like water and broadband.
• There's a great opportunity for disruption in the UK energy market. The big suppliers still dominate, but are not exactly popular. The energy landscape is changing as we move to more dis‑aggregated forms of generation, with less predictability, more dynamism and smarter technology.
• You’ll be working for a company that’s fighting climate change. Our generation arm is the largest investor in solar generation in the UK, and is funding wind and anaerobic digestion. As a supplier, we're helping people to use greener technology and renewable energy, all helping move the UK towards a lower carbon future.

What you'll need:
