(Senior) Software Developer (m/f/x) PLC / Embedded Systems

Who we are

Our goal is a decentralized, flexible, and CO₂-negative energy supply and that’s exactly what we work on every day at Reverion.

We are developing innovative, reversible power plants that can convert gases such as biogas or hydrogen into electricity and heat with very high efficiency, and when needed, reverse the process to transform renewable energy into storable green gases. Reverion power plants achieve efficiencies of up to 80%, making them the most efficient power plants in the world.
