Octopus in Colour Internship 2026 - Mobile Engineering

Addressing Black representation in the energy industry
At Octopus Energy, our mission is to drive the global renewable revolution and make green energy affordable for all. In order to succeed, we need to build a team that represents everyone in our society. Unfortunately, Black professionals make up < 2% of the energy workforce, which is a significant under-representation compared to the ethnic composition of the UK. To help address this, we have created an internship programme that is only open to candidates who identify with any Black, Black British, African or Caribbean background. We are committed to promoting equality, and this internship is an important step in our effort to foster greater diversity and inclusiveness in our business and industry.

Applications for all our internships will close on the 17th April. Please do not upload a CV when asked for 'Resume/CV'.... instead, upload a cover letter made up of no more than 500 words (instructions below) 💚

This is our sixth year running the internship programme. You can hear from our past interns and learn about our previous internships.

What you'll do:

You’ll dive into Electroverse Mobile, the apps driving the Electroverse experience at Octopus Energy, and work toward deploying mobile features to our global user base. You will learn the key skills and architectural patterns (e.g., Git, Swift/Kotlin, mobile performance and accessibility) required to be a world-class mobile developer.

As an intern, you will:

• Work within an existing squad alongside talented developers.

• Build and refine mobile features that live in our customers' pockets.

• Translate Figma designs into fluid, responsive mobile interfaces.

• Learn how to navigate the unique challenges of mobile, from offline functionality to hardware integration.

This is your chance to make a real impact on how millions of people interact with their energy usage every day.

What you'll have:

We’re looking for someone with a natural curiosity for how things work and a knack for problem-solving. You don’t need a formal Computer Science degree, but you should be able to demonstrate a baseline of coding ability and a genuine interest in mobile tech.

We’re looking for applicants with a basic competency in Kotlin or Swift. It would be a bonus (but certainly not a requirement) to have experience with:

• Git, SwiftUI, Jetpack Compose

• Mobile UI/UX principles

• Consuming APIs

• A passion for sustainable tech

Above all, we want someone who thrives on providing alternative opinions and challenging the status quo. If you have a genuine passion for our mission, we’d love to hear from you!

*** IMPORTANT - HOW TO APPLY ***
Follow the link below to be taken to an application form where you will be prompted to 'Attach Resume/CV'. PLEASE DO NOT UPLOAD A CV. Instead, you should upload a cover letter made up of no more than 500 words. 🚀
This cover letter is your chance to stand out! We want to know about you, your passions, and why you think you would be a great fit for an internship at Octopus Energy. We don’t use CVs as we are more interested in what makes you tick than we are about the opportunities you have had up to this point.
It is really important that this cover letter is written by you and really tells us your story. By putting this into AI, your story will get lost. So, while we typically encourage efficient ways of working, please refrain from using AI for this task 🤖
This cover letter is the same for all our internships, so if you are applying for one or multiple positions, you will only need to write one. Please use the below brief of what to include:

• Before your skills and experience, we’re looking for the right kind of person – the kind who is utterly passionate about our mission and who thrives working how we work. So, please let us know why the Octopus Energy Group stands out to you? 🐙
• Tell us about yourself - who you are, what you are studying or have studied, what makes you…you?
• What do you think you could bring to an internship at Octopus Energy?
• Tell us about a time you went above and beyond to help someone else, not because you had to, but because it was the right thing to do.
• If we gave you a stage and 2 minutes to teach the company something, anything, that has nothing to do with energy, what would it be?
