Also worth noting that while there are "Employer of Record" and "Professional Employer Organisation" businesses who essentially have branches with payroll etc all set up in a bunch of countries, and can hire people there and act as the nominal employer while the employee actually works for another company, but at least the last time I looked they were very expensive -- at around thousands of $/€/£ per employee per month.
