Back-end Python Web Developer

BABLE was founded in 2017 as a spin-off from the Fraunhofer Research Society with the goal to create a digital knowledge exchange around smart city topics. This newly created platform was to enable city governments to find the right technologies that can improve the quality of life for their citizens.

The impact of this platform and the following projects BABLE undertook in the years since its foundation increasingly helped to build a missing bridge between the public and private sector. In the last years the expansion from having just a knowledge platform to additionally having a fully distributed team of over 40 experts has enabled BABLE to build a proven track record with impactful projects with key players in the smart city field
