(Senior) Software Developer 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.

Reverion as an Inclusive Company

Don't meet all the requirements? Apply anyway! Studies show that men tend to apply when they meet around 60% of the criteria, while women and non-binary people often feel they need to meet significantly more requirements, even though they are equally well qualified. We are interested in the value you can bring, not in a perfect checklist. No one has everything, and that's completely okay. And if you need any accommodations (e.g. additional time, assistive devices, or similar), just let us know – we'll make it possible!
