I'm curious about whether you tried to find developers in the US but not in Austin or one of the big tech hubs. Or have you found that most of the good US-based developers head for the tech hubs? (Even if that were true before, surely it's different post-pandemic.)
I'm not opposed to hiring good people wherever they are. But some of the challenges discussed above go away when hiring domestically. And, based on the comment elsewhere on this thread about working with companies that recognize the value of good people and are willing to pay above market rate, I gather that the point of hiring in Latam wasn't to be cheap.
