"Mozilla is a global organization, and this role is available in our offices in the European Union, U.S., Canada, or home-based in the U.S., Canada, and European countries where Mozilla has a legal entity. You must have work authorization in one of these countries."
I'm not sure how "home-based" is not "remote". Yes, there are restrictions on possible countries where the employee lives, to do with legal bits like payroll taxes and whatnot.
Bigger companies often have good remote work policies. On the downside, these companies are rarely cool by the usual HN metrics and aren't normally mentioned here except dismissively.
