Hmm - I've moved from London to Helsinki. I've been the hiring manager for several (Software Engineer) positions in Finland and it's been quite interesting.

The supply of CVs for any position we open there for mid/senior positions is a trickle compared to the UK, and it's not really been like they're all perfectly qualified, there's a lot of 'noise' too. We let go of any geographical constraint, as long as you're willing to work close to our time zone and in a nation that we're legally allowed to do business with, then we'd consider it.

In short - if you're an established engineer who's easy to work with and has some initiative, I would not be worried. Salaries/raises might slow down, inflation is here and is going to bite you, but such is life.
