🌍 We’re Revolutionizing Energy to Change the World

At Octopus Energy, we’re not your typical utility company. We’re a team of passionate people working every day to make energy 100% renewable, accessible, and fair for everyone.

We believe technology and innovation are key drivers of change. Our mission is to transform the way the world consumes energy breaking down barriers, simplifying processes, and delivering a more human and transparent service.

That’s why our commitment is clear: clean energy should be the norm, not the exception. To achieve this, we combine sustainability with a people-first approach, delivering outstanding service and building a team that shares our vision.

💡 But none of this would be possible without people like you. To keep growing and transforming the energy sector, we’re looking for talent that wants to make a real difference. If you want to be part of this change, bring your energy, and help build a greener future, we want to meet you!!

🔍 What are we looking for?

We’re looking for a Frontend Engineer to join a very special team within Octopus Energy: the team responsible for building and scaling https://octopusenergy.es/ , our customer onboarding flows, and our customer private area.

You’ll be an active contributor to this space, working with Marketing and other internal stakeholders, and collaborating regularly with our international engineering teams across Europe. You’ll have the support of experienced engineers while taking real ownership of features from day one. We’re looking for someone who enjoys solving real problems for real customers, wants to keep growing technically, and is flexible enough to jump into different areas of the business as needed.

Your focus will be primarily Frontend, but if you’re curious about Backend or have a Fullstack mindset, that’s a big plus.

🐙 We call it the “Octopus Effect”

Working at Octopus Energy means being part of a company where culture and people come first.

💜 We’re committed to flexibility and work-life balance.

🚀 We want you to grow and reach your full potential.

🌱 We believe in a fairer and more sustainable energy model.

We’re waiting for you! 🚀

🧠 What you’ll do

The Octopus Energy tech team is responsible for the sites, services, and tariffs used by millions of customers worldwide. From building cutting-edge time-of-use tariffs to gamifying user experiences, we tackle a wide variety of exciting challenges to push the energy revolution forward.

Our teams are multidisciplinary and collaborate internationally, so you'll have the support and resources to work with top-tier talent and deliver high-impact solutions.

⚙️ As a Frontend Engineer in this team, you will:

Collaborate internationally: Work with Octopus Energy ES and global teams to develop and integrate new features.

Build key product modules: Contribute to the private area, bill management, saving sessions, customer onboarding optimization, and marketing dashboards, all from a frontend perspective.

Deliver fast-paced impact: Ship code that directly impacts customers, with a quick and satisfying feedback cycle.

Grow with support: Take part in code reviews, pair programming, and technical discussions with senior colleagues, and gradually take on more responsibility in architecture and technical decisions.

Thrive in an agile culture: Enjoy flat hierarchies and an open environment that fosters innovation, flexibility, and creativity.

Stay flexible: Be open to working across different areas of the business as priorities evolve, and optionally get involved in backend work (Python/Django, GraphQL) if you’re interested.

💡 Come as you are: We believe diverse teams build better products. We foster an open, collaborative environment where authentic communication and mutual support are key.

🎯 What you’ll need to thrive

Fluent English is essential 🇬🇧. The team is international, so English is the language you’ll use every day.

On the technical side, you should have:

4+ years of professional experience in frontend development.

Solid knowledge of TypeScript and React.

Experience with Next.js, or a strong interest in learning it.

Familiarity with GraphQL (or REST APIs, with a willingness to learn GraphQL).

Experience with CSS-in-JS or modern CSS approaches.

Experience writing tests with tools like Vitest or Jest and React Testing Library.

A collaborative, flexible mindset and comfort working in a fast-paced, evolving environment.

🧲 Nice to have:

Interest or experience in Backend development, particularly Python (Django).
A Fullstack mindset: curiosity about the full picture, not just the frontend layer.
