About the company:

We're on a mission to make a big green dent in the universe by building a truly sustainable energy system globally.

That means making power greener, smarter, and more affordable for everyone.

We put customers at the heart of everything we do: with always-fair prices, transparency and outrageous customer service.

We drive system change: with transformative tech to make renewable energy the norm and end global reliance on fossil fuels.

Octopus Energy Group is made up of 10 businesses spanning 6 countries across 3 continents, including: Octopus Energy Retail, Kraken Technologies, Octopus Energy Generation, Kraken Flex, Octopus Electric Vehicles, and the Octopus Centre for Net Zero. More on OEG @ octopusenergy.group

At Octopus Energy Generation (OEGEN), we're passionate about powering a sustainable future. As pioneers in the renewable energy space, we don’t just invest in utility-scale projects; we invest in people, communities, and a greener tomorrow.

Since stepping into the renewables arena in 2010, we've made waves - becoming a top investor in onshore wind across mainland Europe and the largest backer of solar power in Europe. Today, we proudly manage over £7bn in renewable energy assets worldwide.

In this role you will maintain day to day operation and control of OEGEN’s financial payments systems (SAP, Yooz, Horizon), including user access, master data, workflows and month end system activities. The role supports portfolio growth and system change, ensuring business as usual remains stable while the finance systems landscape evolves and simplifies over time.

Whilst we maintain a degree of flexibility, this position requires an average of 3 days in the office per week

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 [email protected] and we’d love to help!

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

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.
