React Native Engineer (m/w/d)

Job Description

At sonnen, we're driven by a clear goal: creating a future powered by clean, affordable energy for everyone. That's why we make our customers independent - not only from fossil fuels, but also from rising electricity costs.

The key to this independence is our intelligent, all-in-one energy system. It combines solar panels, battery storage, energy tariffs, and wallboxes - all developed and manufactured in Germany.

As the first and only provider in Germany, we also connect thousands of home batteries into one shared network: the sonnenVPP, our industry-leading virtual power plant.

In short: every day, we're working to shape the energy future. And we'd be thrilled to have you join us!
