Do you have a feel for if they might start hiring SDE's again before the end of the month? I was looking into them because it's right up my alley: I'm an aerospace engineer (aeronautics, flight test) turned software engineer who's worked a lot in rotorcraft.
I don't, unfortunately, that's above my paygrade ;-). It's likely going to be a function of the larger hiring situation at Amazon (we're currently in a corporate hiring freeze), rather than something Prime Air specific.
Sounds like you've got a perfect background for Prime Air though! Hopefully we'll be hiring again sometime this year - feel free to reach out (email in profile) if you want to chat more about it.
I saw this recently?
