Software Engineer, Software-Ingenieur, Full Stack Entwickler

Overview

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.

We’re looking for a Software Engineer to join a very special team within Octopus Energy Spain.

This isn’t a traditional dev role; you’ll be part of a small, agile, cross-functional unit focused on quickly building impactful MVPs that make life easier for both our teams and our customers. Your mission will be to identify real needs across the business, propose practical tech solutions, and bring them to life at speed.

If you're curious, proactive, and passionate about solving real-world problems with code, this is your chance to kick off your tech career by doing meaningful work from day one.

• Collaborate closely with different teams (Operations, Marketing, Tech, Customer Support…) to deeply understand their workflows, identify friction points, and turn real needs into technical solutions.
• Design, prototype, and build internal tools or MVPs that optimize processes or enhance customer experience from internal dashboards to smart process automations.
• Build and automate:
  Use your development skills to build services, automate tasks, integrate with internal/external APIs, and work with SQL.
• Identify opportunities, pitch and test ideas fast, and evolve solutions based on real user feedback (internal or external).
• Work in a hybrid, flexible environment where autonomy is encouraged, experimentation is constant, and learning is part of the everyday workflow.
• Grow by doing:
  You’ll learn quickly, supported by a team that shares knowledge, helps you thrive, and celebrates your progress.

• You have a foundation in backend or fullstack development. You don’t need to know every technology on this list; we are looking for someone who has worked with at least one of these (and is excited to learn more):
• Backend:
  Python, JavaScript (Node.js), or Ruby.
• Frontend:
  Modern frameworks like React, Next.js, Vue, or Angular.

Whether you’ve built your skills through personal projects, bootcamps, internships, or your first job experience (it all counts!).

• A technical background in Computer Science, Software Engineering, Telecommunications, or a related field. Whether you're wrapping up your studies or have just graduated, this is a great place to start.
• A genuine passion for solving real-world problems whether they’re internal inefficiencies or user experience challenges, with quick, effective tech solutions.
• Curiosity and initiative: you don’t wait to be told what to build, you explore, ask questions, and identify opportunities on your own.
• Comfort with ambiguity and fast-paced environments; priorities change fast here, and we need people who can adapt and thrive in motion.
• A willingness to fail fast, learn quickly, and improve constantly. You’re not afraid to experiment and iterate.
• Basic knowledge of web technologies, APIs, and databases (SQL), and how modern systems fit together.
• Fluent Spanish and fluent English; we work with international teams and many of our tools, documentation, and meetings are in English.

Bonus points if you've built side projects, automated internal workflows, or created tools to solve a specific problem.

• Location:
  
  Valencia or Remote
• Full-time (40 hours/week)

• Octopus Energy share options
• Office breakfast and fresh fruit
• Flexible benefits (meal vouchers, transport, childcare, private health insurance)
• Support for electric vehicle purchases
• Pension plan
• Training and professional development
• Fun, inclusive and collaborative team culture
• Regular team events (like our “Family Dinners”)

• We do things differently. We believe in a workplace where you can be yourself, grow professionally, and feel part of a team that genuinely wants to change the world.
• We’re a Great Place to Work! On Glassdoor, we’ve been recognized as one of the Top 50 Best Places to Work, and our culture has been highlighted time and again.
• Want to learn more about how we work? Listen to our CEO in this podcast where he talks about our culture and values.
