About the position

Our technology

On the server-side, we mainly use Python. Most of our websites are powered by Django and the Django-REST-framework. We also use Pandas, Numpy and Jupyter for analysis and forecasting, plus Celery, RabbitMQ, SQS and Airflow for background processing.

We use AWS heavily, employing most of the “Hashistack” (eg Packer, Consul, Terraform) as part of a continuous deployment pipeline. See, for example, Django, ELB health checks and continuous delivery.

Client-side, we use React, Redux and SASS; our mobile apps are built using React Native.

What you’ll do

We have lots of difficult design challenges to solve. The Japanese energy market is complicated, outdated and process-heavy - there’s an awful lot of domain modelling that we need to get right.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 difficult technical problems to solve. With the advent of smart meters, we’ll soon be processing 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. There’s a great opportunity for disruption in the Japanese energy market. The energy landscape is changing as we move to more dis-aggregated forms of generation, with less predictability, more dynamism and smarter technology. Octopus Energy were the first UK supplier to introduce a “tracker” tariff whose prices track the daily wholesale prices: http://www.cleanenergynews.co.uk/news/efficiency/octopus-offers-transparency-with-wholesale-price-tariff You’ll be working for a company that’s fighting climate change. Our parent company is the largest investor in solar generation in the UK, and are 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 have

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 equiv. 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
  • React and Redux
  • Ability to speak Japanese would be a plus
