Job Description

Rabot Energy is an independent provider of dynamic electricity tariffs with 100% green energy. Through our innovative procurement strategies, we ensure both ecological sustainability and cost optimization in home energy management. By passing on wholesale electricity market prices directly to our customers, we are able to reduce their electricity bills by an average of 35%.

Owners of electric vehicles and smart meters benefit particularly from our dynamic electricity tariff, as they can automatically charge their vehicles at home when electricity prices on the exchange are especially low. In the Rabot Energy app, charging preferences can be easily set and current market electricity prices can be tracked in real time.

With our intelligent charging solutions, we actively contribute to increasing the share of renewable energy in Germany's overall electricity consumption.

Our vision is to give every customer the opportunity to manage their energy consumption in a smart way while conserving the environment and natural resources. By offering smart charging and energy management solutions, Rabot Energy actively helps drive the energy transition forward. With this idea, we have already won the trust of over 100,000 customers.

Why Now?

The energy market is going through its biggest shift in 50 years. We no longer just manage electricity, we make it intelligent. RABOT is growing triple digits, and our team is growing with it. Now is the perfect time to join: you won't learn inside a finished corporation, but where processes are being built right now. You'll move more and learn more here than in any textbook.

Your Mission

Our app is where customers understand their energy: dynamic pricing, EV charging status, smart home controls, real-time consumption. Thousands of people use it every day, and with every new feature it becomes more critical to our business.

You build alongside us. No sandbox, no practice exercises. Real contributions to our live Flutter app on iOS and Android. You work within our agile squads together with engineers, designers and data teams.

Your Results

We will not throw you in at the deep end, but we expect you to learn how to swim. After three months, your success will look like this:

Month 1 (Ramp-up)

• You understand our app architecture, codebase and development processes well enough to independently ship your first features or bugfixes to the live app.

Month 3 (Performance)

• You regularly deliver code that goes live and is used by real customers.
• Your engineering colleagues trust your work and your ownership over the tasks you take on.

Who We Are Looking For

• Curious mind: You're studying Computer Science, Software Engineering or similar and want to experience real mobile development, not just hear about it in lectures. You already have hands-on Flutter experience (university, hobby or professional).
• Self-starter: You don't wait for the perfect ticket. When you see a problem in the code, you suggest a fix. You use AI tools and modern workflows to work faster and better.
• Team thinker: You don't just write code that works, you write code that others can understand and build on. Clean code isn't a buzzword to you, it's respect for your team.
• Communicator: You work confidently in English, ideally with some German skills. You're comfortable in agile, cross-functional teams and actively participate in code reviews and discussions.

Technical requirements: Experience with Flutter and Dart (university, hobby or professional), solid programming fundamentals, basic understanding of APIs and client-server communication, comfortable working with Git. Availability of at least 6 to 12 months.

Bonus: Experience with state management in Flutter (Provider, Riverpod or BLoC), unit/widget testing, CI/CD processes, implementing Figma designs, or interest in UX, mobile performance or energy/IoT.

What We Offer

• Learning: You work on a live app used by thousands of customers every day. No sandbox, no dummy project.
• Responsibility: Your code goes live. What you build is seen and used by real people.
• Culture: Short feedback loops, honest communication. You're part of the engineering team, not an appendix.

Your Extras

• Employee discount on RABOT Energy electricity tariff
• Urban Sports Club partnership + Deutschlandticket
