Well... Sort of. Every time you make progress with your objective on a mission, he has a chance of appearing. Assuming you have already killed a boss at least once in your lifetime, the best ways to get this bastard to pop up are running defense missions, and if you are solo/not good at defense missions, etc. you can instead run through an exterminate mission. Every kill in these missions counts as progress, hence Stalker seems to spawn on them more. In the end, however, it all comes down to the fickle RNG gods...
