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.

• Contribute to infrastructure monitoring and maintenance across APIs, message queues, databases, and caching layers to ensure optimal performance at scale
• Adapt and optimise systems to handle increased scalability demands as we onboard large new contracts that will significantly increase traffic through the platform

What you'll have...

• Skills you should have:
  • The passion to create something amazing, and the mindset to learn and grow with the company
  • A strong understanding of the Python ecosystem with 3+ years of experience
