About Octopus
Octopus Energy is an energy technology business founded in 2015. Our aim is to drive society’s transition to Net Zero by changing the way customers buy and use energy. To achieve this we:
Build the technology we need to efficiently provide customers with amazing experiences and support - we’ve been a Which recommended supplier 6 years in a row and maintain a Trustpilot score of 4.8 stars
- Challenge the tease and squeeze tactics of traditional energy pricing. We provide fair and transparent pricing that means all our customers get great value for the long term
- Bring renewable energy to our customers - all our products are 100% renewable and we’re working to build new renewable generation right from the customer scale to the grid scale
- Reinvent energy products with smart, data driven tariffs that help to balance customer demand with renewable generation. Our Octopus Agile Tariff, Tesla Energy Plan, Octopus Go EV and Agile Outgoing Solar tariff are all industry firsts and enable our customers to be active players in a renewable energy system

Since 2015, we’ve grown to supply over 5.5 million customers in the UK. We’ve also spread our tentacles and are now in France, Italy, Spain, Germany, Japan, Australia, New Zealand & the U.S. Our in-house developed technology platform, Kraken, is licensed by retail giants including E.ON in the UK, Origin Energy in Australia and Toyko Gas in Japan.

About our Data Platform Team

At Octopus we’ve developed a data platform that provides data services to the business in the UK and our retail energy businesses around the world. The platform enables self-service of data analytics to hundreds of data hungry users as well as automation of all our data workflows from simple ETL jobs to ML training and prediction. 

The data platform team works across the whole customer domain on anything from natural language understanding of our customer communications to processing billions of smart meter readings to build customised smart energy tariffs.

As the volume, scope and geographical range of our data services rapidly expand, we’re looking for an experienced data engineer to join the team to help us build and maintain our platform, pipelines and data sources.

This is a fantastic opportunity to work on data problems that genuinely move us closer to Net Zero with a company that is passionate about building great technology to change the way customers use energy.

We would prefer someone who can work in our London office but will consider remote candidates (warning: the bar is much higher). You do need to be able to work in the UK without a VISA though.

Above all, we’re looking for someone who thrives on providing alternative opinions, challenging those around them and being challenged.

If this sounds like you then we'd love to hear from you.

Studies have shown that some groups of people, like women, are less likely to apply to a role unless they meet 100% of the job requirements. Whoever you are, if you like one of our jobs, we encourage you to apply as you might just be the candidate we hire. Across Octopus, we're looking for genuinely decent people who are honest and empathetic. Our people are our strongest asset and the unique skills and perspectives people bring to the team are the driving force of our success. As an equal opportunity employer, we do not discriminate on the basis of any protected attribute. Our commitment is to provide equal opportunities, an inclusive work environment, and fairness for everyone.
