About The Company
1KOMMA5° wurde gegründet um Millionen Gebäude in Europa klimaneutral immer mit dem günstigsten Strom zu versorgen - ganz ohne fossile Energie. Mit „Heartbeat AI“ betreibt 1KOMMA5° Europas größtes dezentrales Kraftwerk. Heartbeat AI steuert Elektroautos, Batterien, Wärmepumpen oder Klimaanlagen und handelt sie in Echtzeit an der Strombörse. Das System kauft Strom wenn er besonders günstig ist und verkauft Strom wenn er teuer ist. In Summe profitieren Nutzer von nahezu kostenlosem Strom. Das Konzept gilt als günstigere Alternative zu fossilen, zentralen Kraftwerken und könnte laut einer Roland-Berger-Studie aus dem Jahr 2025 bis zu 255 Milliarden Euro an Stromkosten einsparen. Inzwischen steuert „Heartbeat AI“ rund 50.000 Energiesysteme mit einer Leistung von 600 Megawatt, was etwa der Leistung eines modernen Gaskraftwerks entspricht. 1KOMMA5° ist aktuell in sieben Ländern aktiv und betreibt 80 Standorte, um Installation und Service als "One Stop Shop" für Kunden regional und in höchster Qualität sicherzustellen.
About the Role

1KOMMA5°

At 1KOMMA5°, we pursue a clear vision: Living on wind and sunlight forever for free. To make this a reality, we are building the energy system of the future with Heartbeat AI. Want to be part of it?

We bring together regional craftsmanship and scalable software: We don't think of solar, batteries, heat pumps, and e-mobility as isolated components, but control them as an intelligent, integrated overall system in our virtual power plant. Directly connected to the electricity market – in real time, fully automated. This way, energy is used when it is available from renewables and particularly cost-effective. By 2030, our goal is to transition 1.5 million households to renewable energies. Over 3,000 people are working towards this every day, at more than 80 locations worldwide, from Finland to Australia.

Want to take responsibility and build solutions that truly matter? Apply now and help us shape the energy world of tomorrow.
