The job poster doesn’t expect anyone to apply; they’re looking to justify an H1b visa application.
not for THAT job they don’t. No one who works launch vehicles or air vehicles with those skills or the sw side of launch/air vehicles in defense can be on a visa. They need at least a TS clearance or SAR AND program access. Not sure what SpaceX requires but the Boeing / Lockheed ULA tribe work cannot be done by a foreign national.....period.
