Earlier quoted context omitted.
> All jobs should be remote-friendly Would be helpful to mention where by the way; some positions are world-wide remote, others Europe or US only.
Indeed. Some companies limit to countries, some to timezones (+/- a few hours), some to regions like you mentioned, and others might have a language requirement. I've been trying to figure out how to surface that properly without making it too complicating for either the poster or the viewer, and I'm honestly not sure yet.
Timezones are often more flexible, and I wouldn't bother too much with that. But location often doesn't have that due to legal hassle etc (other than visa sponsorships).
