Former SDAZ pilot here. In general, SDAZ always 'needs' pilots, but they don't always need one *today*, if that makes sense. You might be hireable and liked by them but it could take a couple months before an expected pilot position opens up for you from when an 18 month 'veteran' leaves for a new job.

And yes, be persistent. Everyone who gets hired there does more than merely drop off a resume and then disappear (or was well connected).

It's a fun job in a fun sector of the aviation industry, but like any place, there's still things that also could be better about it. None of which would dissuade me from suggesting people go there.
