Hi Nini!

Saw your post as I was searching on "Chicago". I live (t)here right now and consider moving to CH so I was looking for someone who walked the steps already.
As on your questions on the positions - have you tried LinkedIn? It's a nice site for building network of people. And it also has groups. One of the Swiss groups, which I belong to, seems to have people who sometimes look for others in your area.
Give it a try!

Good luck!
