Work at the national or European level?
IS is part of a wider European association called ESN. ESN encompasses almost 14 000 volunteers working for 470 sections like VIS, all over Europe. All those people are organized by several hierachical layers, from the national level (ESN Sweden) to the international board working and living in Brussels.
VIS is an old and influential section in the network; in fact, the current president of ESN, Stefan Jankhe, used to be VIS' webmaster in from 2009 to 2011! The last president of ESN Sweden was also VIS' president in 2012, and no later than summer 2014, both the marketing responsible and the webmaster of VIS became Communication Manager at the national level and chair of the international IT Committee, respectively. VIS in an excellent opportunity if you're interested in supporting the Erasmus spirit and making the lives of students better everywhere in Europe.
