There absolutely are remote first roles in the US, but the competition is also extremely intense. The median SWE and HNer wouldn't make the cut.
It also requires a level of maturity, clear thinking, self-starterness, and independence that is hard to come by without a proven track record and experience.
My advice is for the median/average SWE and HNer, not for the truly exceptional.
Spending a 7-10 years in a hub and then going remote first is the best path because you build the network you need to get referrals to vouch for you as a remote-first hire well as the track record needed to go remote-first.
