It seems the biggest question is, “do you really want to move to Switzerland?” That’s a big change.
The next biggest question is, how will this affect you financially, not just the pay, but the final savings after all the taxes and expenses.
And I think third is the career trajectory, if you really want to be in management or are happy as an individual contributor.
There are lots of jobs out there. You can find a better fit if this isn’t the right one.
