(Senior) Software Engineer (f/m/x)

Our goal is to have a solar system on every roof, a storage unit in every house, and an electric car in every garage. Enpal makes this possible with an integrated total solution for decentralized energy—from solar systems and battery storage to wall boxes, smart meters, and heat pumps. At the heart of it all is our AI-powered platform Enpal.One +, which intelligently connects thousands of systems and efficiently optimizes electricity procurement and feed-in on the energy market.

Enpal Energy is Enpal’s electricity division, making clean energy accessible to every household—from Germany’s most affordable electricity rates to smart energy solutions that optimally integrate generation, storage, and consumption.

With ambitious growth targets and a rapidly expanding customer base, we are building a team that is actively shaping the German energy market. In doing so, we combine startup agility with the scale of a market leader—across all areas, from operations and technology to finance, customer support, and product development.
