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

Reverion is a German deep-tech energy company that develops reversible fuel cell systems for highly efficient power generation, electrolysis, energy storage, and carbon capture. Spun out of the Technical University of Munich (TU München), the company produces modular power plant systems capable of converting biogas or hydrogen into electricity at efficiencies of up to 80 percent — roughly double the efficiency of conventional combined heat and power (CHP) systems. Their systems are designed to serve applications ranging from agricultural biogas plants to large-scale industrial energy infrastructure. Reverion's technology is centered on solid oxide fuel cells (SOFCs) that can operate reversibly, switching between power generation and electrolysis modes with short transition times. This enables the systems to function as both a power plant and an electrolyzer, converting surplus renewable electricity into methane or hydrogen for storage and later use. The hydrogen systems achieve a round-trip efficiency of up to 75 percent, supporting sector coupling and grid stabilization. Unlike conventional combustion-based power plants, Reverion's systems operate emission-free, and the CO2 separated during the process can be utilized industrially or stored permanently, enabling climate-positive energy production. Reverion's mission is to advance the energy transition by replacing fossil-fuel-based power generation with clean, highly efficient alternatives that are both ecologically and economically viable. The company combines cutting-edge research with real-world deployment, with operational projects demonstrating its technology's performance in the field. Reverion positions itself as a pioneer in next-generation energy infrastructure, targeting a future of stable, flexible, and climate-friendly energy supply.

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.
