Overview
Location: Hamburg, Germany (Hybrid – up to 2 remote days/week)
Tech Stack: .NET / C#
As a Senior Software Engineer (Backend), you’ll work on the systems that connect large energy assets (such as EVs and heat pumps) into our ecosystem. Your work will directly enable customers to integrate new hardware providers, optimize energy usage, and unlock the full potential of dynamic energy pricing.
This role sits at the intersection of hardware integration, backend platforms, and energy intelligence, and is ideal for an engineer who enjoys complex integrations, distributed systems, and close collaboration with product and data teams.
What You’ll Do

By passing on exchange buying prices to our customers, we can save them up to 35 % on their electricity bills. Electric vehicle owners particularly benefit from our dynamic electricity tariff, as we have developed a smart system that signals the car when to automatically charge during periods of low electricity prices. And this is just the beginning!
Our mission is to empower every consumer to efficiently manage their energy consumption costs while safeguarding the environment and natural resources. Through our provision of 100% renewable energy and comprehensive smart charging and energy management solutions for homes, RABOT Energy actively contributes to increasing the real green power share in Germany's electricity consumption, thus driving the energy transition forward.
