Senior Backend Developer (m/w/d) - Germany based

What you’ll do:

• We have lots of difficult design challenges to solve. The utilities market is complicated, outdated and process-heavy - there's an awful lot of domain modelling that we need to get right.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 Kraken to improve other utilities like water and broadband.
• There's a great opportunity for disruption across the 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:

• Good communication in English - other languages such as German, French, Italian or Spanish is a plus

• Writing robust and fault-tolerant software: You can write robust and fault-tolerant software that runs smoothly and reliably even under adverse conditions.
