Electroverse is looking for a talented, passionate Software Engineer to join our team and help build the foundations of the global EV transition.

About Octopus Electroverse

We’re making electric vehicle public charging simple, by building the giant, virtual charging platform of the future. In just five years, Octopus Electroverse has become Europe’s largest eMobility charging network, with over 1.4 million connected electric vehicle chargers globally across 79 countries. Our customer ecosystem spans web, iOS, Android, CarPlay, Android Auto & Automotive OS.

But this is just the start: we’re busy expanding internationally, growing our Charge Point Operator and OEM partners, and scaling our Octopus Fleet B2B proposition - all in the name of making public EV charging super simple for our customers. Electroverse is a cross-functional team of product, engineering, commercial, operations and marketing, all sharing a passion for shifting the industry towards EVs.

About the Job

You’ll join the Core squad - the team running the technical foundations of everything Electroverse does. Working alongside our Technical Product Manager and backend team, you will help develop the critical logic and resilient platform infrastructure that powers our B2C, B2B and API features.

Our work spans a broad and dynamic remit - from integrating new and supporting existing CPOs using our partner portal to improving the reliability of the charging experience, implementing bespoke pricing solutions, and driving architectural efficiency.

You’ll have the chance to work on highly impactful projects, fueling product innovation in a fast-moving industry and influencing how the back-end scales to keep Electroverse at the forefront.
