I got my first remote gig (firmware work) through a friend's referral, however that was years before COVID-19. These days I'd suggest looking for a remote-first company. Or, maybe apply for remote gigs that say US-only (assuming there's not an obvious or stated reason), then bring up your location when talking to a real human.
FWIW - technically I run a NZ company, so am a contractor and not an employee of the company that my day-to-day manager works for. This arrangement seems to be common among people who work for US companies, or are US citizens, which brings up some questions about the stats in the article...
100%. There are 2 NZ employment markets. Those working for NZ companies in the $100k region, and those working for US firms for the $200+k region.
I've had an annoying time explaining this to past US employers when they present median values for NZ salary fudge factors.
