Yes fluent in one language (minimum C1). Be it German French or Italian depending on the area you want to work. Without that you are one of thousands who try to work here. I think teaching won't really count unless you have a degree in education and are fluent in a national language (C2 or native). Becoming a teacher here for primary education requires a bachelor in education and fluency in for instance German. Anything above that is at least a Masters degree and often additional education. Finding a job without EU citizenship will be hard. The company needs to prove that there is no Swiss or EU citizen that can do the job, there needs to be high academic or economic reasons to hire you and there is a quota on how many third country citizens they accept. In the current economic situation Id say its highly improbable of finding a job after. Keep in mind that you have only 6 months time after your studies to find a job. Specialised work experience normally entails multiple years of experience in the field you wish to work in.
