The UIA are seeking motivated professionals with a good overview of sustainable urban development in the EU. They should have experience in supporting urban authorities in implementing bold and innovative solutions as well as skills in capturing and sharing knowledge. Becoming a UIA expert will give applicants the possibility to join a select group that will support these bold and pioneering projects and will actively contribute in drawing lessons to be made available to a wider audience of policy makers and practitioners in Europe and beyond. UIA Experts will be contracted for a total of 50 days of expertise covering the implementation phase of UIA projects (three years for implementation plus one final year for knowledge transfer).
