IT - Director:in (CTO)

Internship Senior

Job description

We are a young team from the RWTH-Aachen area, making the energy transition practical: With Calvergy, we're building a KI-gestützte Plattform that depicts corporate energy systems as digital twins, comparing options like abwärmenutzung, BHKW, Wärmepumpe, KWK, PV or battery and deriving clear and sustainable supply concepts from them.

Our Vision: a tool that's so simple that you can find viable solutions for complex energy systems with just a few clicks – intuitive, fast, and reliable. This way, users will save time and effort and find optimal solutions to reduce energy costs by up to 25% and significantly lower CO2 emissions.

You'll work directly with the founding team, test ideas quickly with real users, and see your impact immediately. Short paths, a lot of ownership, and a true start-up tempo.
