If you have the skills, they have the coin.
They won’t hire some react guy in X country but someone who can find compiler bugs and save them XX+ million dollars a year? Heck yeah.
I'm in a similar position where I'd like to do something a lot more interesting, but intersection between where the interesting companies have offices and where I'd be willing to live do not really overlap enough justify rooting up my life.
(Unless we're talking about "too good to ignore", that's a different story.)
Anyone who can optimize a company’s bottom line will be hired.
Like I said, no random average mid react guy or dime a dozen Java developer is getting hired as a remote employee in some flyover country.
But if someone can provide like 50x value then hell yeah..
I thought that was obvious in my message considering we are discussing compiler optimization
I think there's also quite a big spectrum of skill, even when we're talking about compiler optimization and highly skilled software developers. I'd put myself up there, but still I'm no Lars Bak (for whom Google allegedly created an office in Denmark).
If you're asking what would constitute someone being special, it would depend on the role and skillset. As I said in my earlier comment, someone who is a beast and can find and fix bugs in compilers is a rare person. Especially if that skillset can help the company save boatloads of money that can be deployed elsewhere.
There are probably only a handful of people in the world who understand and can push the AI landscape forward. A lot of them are Chinese immigrants, and yet OpenAI/Meta/etc are paying them boatloads of money.
As for remote roles, I once worked on a project where we hired some dude for like $500/hr as a contractor because he was one of the few people who knew the inside/out of postgres and oracle rdbms because we were doing some very important migration.
