Software Engineer - Backend & Cloud (m/w/d), Veli, DE

We are Veli, a startup with a clear mission: Turning households into guardians.
Our AI-powered solution analyzes and interprets existing electricity and water consumption data and checks in real time for anomalies in household activities. This allows us to detect, for example, accidentally left-on stovetops, leaks, or even emergencies involving people living alone and to call for help.

The Veli AI is already in use by leading providers in assisted living and emergency call services. We are supported by experts and experienced investors from the fields of care, energy, and tech, with whom we are aiming for our next goal: bringing Veli into millions of households.
