About The Role Our client is driving a digital transformation for local governments, building a major information hub for Flanders through the "Local Decisions as Linked Open Data" (LBLOD) ecosystem.

As a key builder in this ecosystem, you’ll help solve this challenge by developing and scaling semantic applications that enable seamless, efficient, and transparent digital service delivery. Your work will directly impact how local governments operate and interact with their communities, setting new standards for public sector innovation.
