You have to find a company that would convince the authorities that they have been looking for qualified workforce on the Swiss/EU market and were not been able to find anyone suitable in 6 months thus you deserve a visa.
meh, just keep your existing remote WFH job, but have your home be in Zürich. You might need to work some offset hours to keep your meetings. Now, you're just on a tourist visa. Check it out for however long your tourist visa allows, and then if you don't actually like, it's a lot easier to leave. One step closer to being a digital nomad
I'm currently ~1k eur/month (altough remote), and I doubt that's a survivable amount for .ch. And a tourist visa is kinda not something could save my life now. If available, at all.
Google still has some open positions in Zürich!
