My two cents

Yes! A simple proof is that as I write this answer in March 2023, I've found 12 new open swiss job positions targeted to Service Design practitioners in the last month.

So, in other words, 3 new jobs per week! This is a huge change compared to a few years ago.

And these are just the "visible" jobs and those targeted at service designers. Most service designers could work in many more types of roles like UX research, workshop facilitator, etc.

So, there is definitely a future for someone studying Service Design in Switzerland.
