We’re making electric vehicle ownership as smart and simple as possible, by building the world’s largest, public charging platform.

In just four years, Octopus Electroverse has grown to become one of the largest eMobility players globally, with over 850,000 connected electric vehicle chargers and a customer ecosystem spanning web, iOS, Android, CarPlay, Android Auto & Automotive OS, and more.

But it’s just the start: we’re busy expanding internationally, working with more automotive and tech partners, building exciting new features at scale, and creating the integrated charging experiences of the future - all in the name of making public EV charging super simple for customers.

Electroverse is a multifunctional team made up of product, development, commercial, operations, marketing, partnerships and more - all focused on making Octopus Electroverse the go-to name in public EV charging. And we’re looking for smart individuals with an interest in the space who can help us make it happen.

We’re looking for someone who’s passionate about code, curious, and eager to learn. You’ll be working alongside the backend engineering team that provides services for our Electroverse ecosystem in the electric vehicle and electrification space with focus on helping develop the business proposition for external partnerships and APIs.

Our project is at an exciting time in its lifecycle; maturing quickly but still with plenty of opportunities to work on big features and scaling the product to meet new challenges, giving you the chance to have a huge impact within the team and wider industry.

Overall, you'll work with a small, high-energy project team to bring the product to life - an exciting opportunity to work like a start-up within a rapidly scaling EnTech business.

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.
