At Octopus, we hire great people who get stuff done, all whilst being themselves. If this sounds exciting, we’d love to chat. We have a preference for candidates who can work hybrid from our London office, but we're open to fully remote candidates (you do need to be based in the UK). Why else you'll love it here • Wondering what the salary for this role is? Just ask us! On a call with one of our recruiters it's something we always cover as we genuinely want to match your experience with the correct salary. The reason why we don't advertise is because we honestly have a degree of flexibility and would never want salary to be a reason why someone doesn't apply to Octopus - what's more important to us is finding the right octofit! • Octopus Energy Group is a unique culture. An organisation where people learn, decide, and build quicker. Where people work with autonomy, alongside a wide range of amazing co-owners, on projects that break new ground. We want your hard work to be rewarded with perks you actually care about! We were named the UK's top company to work for in 2025, and we ranked in the top ten in the Sunday Times Best Places to Work 2026. Our Group CEO, Greg has recorded a podcast about our culture and how we empower our people. We’ve also been placed in the top 10 companies for senior leadership • Visit our UK perks hub - Octopus Employee Benefits If this sounds like you then we'd love to hear from you, tell us what you care about, why Octopus feels right and most importantly, bring us the real you! Applying for jobs can be a bit scary so have a nose through some of our tips first🚀 P.S. Our process usually takes up to 4 weeks, but we’ll always do our best to flex around what works for you. Along the way, you’ll chat with our recruitment team and your Recruiter will help you throughout different stages. Got any burning questions before then? Drop us a message at talent@octoenergy.com and we’d love to help! Are you ready for a career with us? We want to ensure you have all the tools and environment you need to unleash your potential. Need any specific accommodations? Whether you require specific accommodations or have a unique preference, let us know, and we'll do what we can to customise your interview process for comfort and maximum magic! 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. **Live in Octoenergy’s hiring system.** Read from the company's own applicant tracking system, not reposted from a job board — so it's a real, open requisition rather than an ad that outlived the role. We remove it as soon as it disappears at source. ## More jobs like this - ML [Mid Level Data Engineer - PensionBee](https://gurify.com/job/mid-level-data-engineer-pensionbee-e6f2779bae81) London, United Kingdom · last week - RI [Senior Data Engineer I (Data Platform)](https://gurify.com/job/senior-data-engineer-i-data-platform-at-rightmove-5f2e2868cd2f) Rightmove · London, United Kingdom · 3 weeks ago - IN [Staff Data Engineer - GTM](https://gurify.com/job/staff-data-engineer-gtm-at-intercom-05f990e2ccd6) Intercom · Dublin, United Kingdom · 2 weeks ago - CA [Data Engineer](https://gurify.com/job/data-engineer-at-capitalontap-e2fd3bc7067c) Capitalontap · London · 2 weeks ago - RI [Senior Data Engineer II (Data Platform)](https://gurify.com/job/senior-data-engineer-ii-data-platform-at-rightmove-36cdabc0739f) Rightmove · London, United Kingdom · 3 weeks ago - SP [Senior Data Engineer - Data Platform](https://gurify.com/job/senior-data-engineer-data-platform-at-spotify-790df5fb532a) Spotify · London · 3 weeks ago ```json {"@context":"https://schema.org/","@type":"JobPosting","title":"Senior Data Engineer","description":"\u003Cp\u003EWe\u0026#39;re making energy fair, clean, and simple for all using technology.\u0026#160;\u003Cbr /\u003EOctopus Energy started with a bold idea: to build Britain\u2019s first truly digital energy supplier.
