What they need


Who you are

  • Python (minimum 7 y.e.)
  • Django (or equiv. web framework)
  • Fluent in French, and level B2 at least in English
  • Domain modelling
  • HTTP and REST APIs
  • Writing robust and fault-tolerant software
  • Celery and async processing
  • Postgres
  • AWS
  • Terraform, Packer, Consul
  • React and Redux

What the job involves

  • We have lots of difficult design challenges to solve. The French energy market is complicated, outdated and process-heavy - there's an awful lot of domain modelling that we need to get right.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
  • You will be working in a multi-disciplinary software engineering team; solving design challenges; domain modeling; solving technical problems; engineering solutions for smart meters, writing robust fault-tolerant software primarily in Python and Django, Celery, and async processing
  • We have lots of difficult design challenges to solve. The energy market is complicated, outdated, and process-heavy - there's an awful lot of domain modeling that we need to get right.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
  • There's a great opportunity for disruption in the energy market. The big suppliers still dominate but are not exactly popular. The energy landscape is changing as we move to more disaggregated forms of generation, with less predictability, more dynamism, and smarter technology. Octopus Energy was the first UK supplier to introduce a "tracker" tariff whose prices track the daily wholesale prices: http://www.cleanenergynews.co.uk/news/efficiency/octopus-offerstransparency-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 is funding wind and anaerobic digestion. As a supplier, we're helping people to use greener technology and renewable energy, all helping move the world towards a lower carbon future
