Most of our websites are powered by Django, Django-REST-framework, and GraphQL (Graphene). We use AWS heavily, employing most of the 'Hashistack' (eg Packer, Consul, Terraform) as part of a continuous deployment pipeline. Client-side, we use React, Redux, and SASS; our mobile apps are built using native code or React Native.What You'll Do 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 The energy market is complicated, outdated, and process-heavy - there's an awful lot of domain modeling that we need to get right.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.
