I definitely wouldn't say it's easy. For me it was mostly networking (I didn't even apply for the job, I was asked to interview): academic publications, attending international conferences, involvement in public activities, github (well, SourceForge back in the day), FlipCode articles (now defunct, but you get the pictures), posts on compsci.algorithms newsgroups (dating myself), etc.
As a secondary, observation, around when I finished my degree, the University had a ton of interest from overseas companies and SA expats in these companies. I recruited several people from SA myself some 12-15 years back. Amusingly, I posted a few job adverts at the university a few years back, and received zero interest. Talk about looking a gift horse in the mouth. If you studied at a university it may be worth checking to see what's been added to your FB groups or whatever.
