Are there companies hiring software devs outside their own country?

I live in a small country with relatively few prospects for developers with 3+ yrs experience. Employers here rather take advantage of the situation to create some pretty toxic workplaces.

So I'm looking for a job working remotely for a US or European company but I'm seeing a lot of remote jobs advertised solely for specific countries, which is fair enough. I get that the tax and employment situation must be pretty hairy if they venture outside their borders.

Does anyone know of reputable companies hiring contractors from overseas?

Any other words of advice that occur to people would be appreciated too.
