🔭 Our mission & vision

Job Description

Help us make a big green dent in the universe. We're on a mission to drive the global renewable energy revolution, and we need loads more people to help us make our vision a reality.

Our teamAll technology is written and maintained by a multi-discipline engineering team of around fifty people. This includes server-side, client-side and mobile engineers working closely with UX experts, copywriters and designers.We follow a Kanban-like approach, using Google docs and Asana to specify and manage work; Github, CircleCI and Terraform Enterprise as part of an immutable-infrastructure, continuous delivery pipeline; and Loggly, Sentry and Cloudwatch to measure performance and monitor production.

Engineering standards are high. We pair program, thoroughly review and test code before it deploys, and maintain fast, high-value test suites. We have weekly tech talks, monthly blitz-days (eg sharpening our internal tools, upgrading dependencies) and can often be found at tech meet-ups and conferences.Our coding conventions are open-source and we maintain a tech blog.

Octopus is a great place to learn, work with some talented engineers and level-up your skills.

Our technologyOn 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 doWe 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 The Japanese energy market is complicated, outdated and process-heavy - there's an awful lot of domain modelling that we need to get right.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.
