Together with the Flemish Government, Cegeka’s Flanders Digital aims to propel Flanders into the top five most digitally advanced regions in Europe. As the strategic IT partner of the Flemish Government, Cegeka is driving Flanders’ digital transformation in areas such as digital workplaces and developing applications that impact the lives of 6.6 million Flemish citizens, just like you and me. Consider, for example, the Growth Package, which ensures that 960,000 Flemish families automatically receive the correct benefits and allowances, or the Flemish Enforcement Platform for the Justice and Enforcement Agency, where administrative enforcement information from various inspection services across Flanders is centralized. The Education Agency is also rolling out the Persona application to manage staff data. And these are just a few of the many projects we're involved in. For these projects, we’re constantly looking for talented, motivated people. Are you eager to help build a digital Flanders? You might be our new Senior Java Developer!
