Working Student (m/f/d) Backend Engineer, B2B Squad

Rabot Energy is an independent provider of dynamic electricity tariffs for households and businesses. With smart procurement strategies and automated control, we shift flexible consumption into hours with low exchange prices. That way, households and businesses optimise their electricity costs. Our vision is to give all customers the ability to steer their electricity consumption smartly and benefit from low-price exchange hours.

Why Now?

The energy market is going through its biggest shift in 50 years. We no longer just supply electricity, we make it intelligent. RABOT is growing triple digits, and our B2B business is growing with it. Behind it runs the backend that makes it all work.

Now is the perfect time to join: you will not learn inside a finished corporation, but where things are still being built. As a working student in our B2B squad, you ship real backend features with C# and AI, and move more than in any textbook exercise.

You build backend features for our B2B squad in C#, and you use AI tools to build faster and smarter. You work closely with our engineers on the systems that power our business with commercial customers.

You start by working on smaller engineering tasks with the help of your peers, then take them on independently, and grow into medium-sized tasks over time. No practice exercises, real backend that goes live and that our business relies on.
