amaraya,
The good news is that there are lots of positions in Geneva for qualified teachers.
The bad news is that you will need a permit. If you already have a permit, then there is only good news.
Some of the information in this thread will be of help:

I'm not sure, but this organization may be looking for part-time teachers for the 2009-10 academic year.

Also, you should check with all of the international schools in Geneva. They usually start hiring teachers at this time of the year, so there may be some openings.
Geneva is a bit too far for me to travel for work, but while I was searching for a position, I noticed some interesting options with the United Nations, some of the missions, and with the US Embassy.
Good luck!
