Python Software Developer - Flexibility

Python Software Developer - Flexibility Applications (f/m/d)

In the Software and Data Services unit at Next Kraftwerke, we use agile methods to develop sustainable software solutions for the European energy transition. With a growing portfolio of batteries, solar, wind, and biogas power plants, taking advantage of these assets’ flexibility is necessary to respond to fluctuations in renewable energy production. You will develop applications with which our electricity traders can react to price signals and utilize our flexible assets in the most profitable way.

In our open-minded and cooperative working environment, we offer you the opportunity to work on topics that are highly relevant to the energy transition, to contribute your programming expertise and to continuously develop yourself and the team.
Flexible working time models are not just an empty phrase for us, but an everyday reality at our company. Whether full-time or part-time, we’re open to finding a solution that suits you.
