Software Engineer

Summary

Join Octopus Energy, a revolutionary energy company committed to 100% renewable energy, as a Software Engineer. This isn't a traditional role; you'll be part of a small, agile team building impactful MVPs to improve internal processes and customer experience. Collaborate with various teams to identify needs, design solutions, and build internal tools using Python, JavaScript/Node, or Ruby. You'll need backend development experience, a technical background, and a passion for solving real-world problems. The role offers a hybrid, flexible work environment, opportunities for growth, and a chance to make a real difference. Octopus Energy prioritizes a positive work-life balance and a supportive team culture.

Requirements

• Solid experience with backend programming using Python, JavaScript/Node, or Ruby through personal projects, bootcamps, internships, or early 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

Responsibilities

• 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
• Use your backend development skills (in Python, JavaScript/Node, or Ruby ) 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

Preferred Qualifications

Bonus points if you've built side projects, automated internal workflows, or created tools to solve a specific problem, we’d love to see what you’ve built!
