IoT Solution Architect & Embedded Software Engineer (f/m/d)

Did you know, that according to the United Nations about 4 billion people are facing water scarcity at least one month of a year? At the same time, 30% of water is lost globally through leaks and bursts in water distribution networks. The solution is a smart water network and an active water loss management. But water utilities are missing data to prevent leaks and manage their network efficiently. PYDRO’s mission is to preserve water! Our self-powered solutions are unique and we can change the way of managing water networks worldwide.
