The role
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 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 multi-disciplined and collaborate internationally, meaning you'll have the support and resources to work with top-tier talent and deliver high-impact global solutions.
- Collaborate internationally: Work closely with Octopus Energy ES and various global teams to develop and integrate new features.
- Own key product modules: Contribute directly to the private area, bill management, saving sessions, customer onboarding optimization, and marketing dashboards, all from a frontend perspective.
- Drive fast-paced impact: Deliver code that directly impacts customers. Our priorities adapt to real-world needs, meaning the pace is fast and the feedback cycle is satisfyingly quick.
- 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-related work (Python/Django, GraphQL) if you have the interest and skills to do so.
💡 Come as you are: At Octopus, we believe that diverse teams build better products. We foster an open, collaborative environment where authentic communication and mutual support are key. If you love to connect, share ideas, and solve complex problems alongside a supportive team, you'll fit right in.
🌍 We're Revolutionizing Energy to Change the World
🔍 What are we looking for?
We're looking for a Senior Frontend Engineer to join a very special team within Octopus Energy - the team responsible for building and scaling octopusenergy.es, our customer onboarding flows, and our customer private area.
You'll act as the technical driver of this space, working hand in hand with Marketing and other internal stakeholders, while collaborating regularly with our international engineering teams across Europe. We're looking for someone who thrives on solving real problems for real customers, who's comfortable owning frontend architecture end-to-end, and who's flexible enough to jump into different areas of the business as needed.
Your focus will be primarily Frontend, but if you have an interest in Backend or a Fullstack mindset, that's a big plus.
