Backend Developer – Node.js (m/f/d)

Solarize is a startup of an experienced founding team in the field of B2B Software as a Service. We automate the billing of electricity deliveries in commercial tenant power & microgrid projects.

To advance the energy transition, we as a founding team are working for a future that enables every building to produce and consume electricity locally. Our software solution offers utilities, building owners and builders of solar power systems the opportunity to increase their revenues and reduce the complexity of commercial tenant power projects.

You will directly support the founding team with your work and have a direct impact on the future of a rapidly changing energy market. If you have always been thinking about breathing some start-up air and participating actively in early stage company growth, we look forward to hearing from you. At the same time, tenants profit from green energy that is cheaper than the one from the grid.
