Senior Software Engineer – Customer Entities

Company: Kraken
Apply for the Senior Software Engineer – Customer Entities
Location: London
Job Description:

Help us use technology to make a big green dent in the universe! Kraken powers some of the most innovative global developments in energy.

We’re a technology company focused on creating a smart, sustainable energy system. From optimising renewable generation, creating a more intelligent grid and enabling utilities to provide excellent customer experiences, our operating system for energy is transforming the industry around the world in a way that benefits everyone.

It’s a really exciting time in energy. Help us make a real impact on shaping a better, more sustainable future.

The Customer Entities team sits at the centre of the Kraken Customer system; providing the foundations for the customer’s experience. It provides representations of the core parts of the system – an account and customer’s identity. It also provides address information to the system, which is key to many parts of the system, such as ensuring communications are sent to actual verified locations. 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 The UK utilities market is complicated, outdated and process-heavy – there’s an awful lot of domain modelling that we need to get right.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, such as 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. We also consider how to adapt Kraken 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

We’re looking for someone with a general interest in technology and problem‑solving; someone diligent and thoughtful. It would be helpful to have experience/expertise in the following (in rough priority order):

  • Python
  • Django (or equivalent web framework)
  • Domain modelling
  • HTTP and REST APIs
  • Writing robust and fault‑tolerant software
  • Celery and async processing
  • Postgres

Plus experience in the following would be a bonus:

  • AWS
  • Terraform
  • Packer
  • Consul
