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.

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.

- 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
