Do you mind sharing where the company you work for advertises open positions? You could just share 5+ such sites to avoid revealing anything if you are concerned. I'm at the tail end of interviewing and have some great options however finding open remote positions at remote-friendly companies can be difficult.
I've been looking at sites like weworkremotely.com and remoteok.io.
1) From people I know well who make a solid recommendation.
2) At major tech conferences.
Hiring is a very risky and high stakes proposition. A new hire easily costs us a million or more if it doesn't work out. We are very cautious, and I take our hiring process very seriously.
Junior positions we typically recruit from Univerisities in the region with top CS and ECE programs since they are less likely to be skeptics of fly over country.
