If you read the actual source article in National Geographic, you'll find that the Horten brothers were in fact Nazis.

Still, even if they were not Nazi's, English is sufficiently malleable that Nazi engineer could mean simply an engineer employed by the Nazi's.

Is every "Google engineer" an actual Google?

It's a bit more akin to now calling all Lockheed Martin engineers "Obama's Engineers".

No, that only applies if they work at GM.

No, it would be like calling them US engineers, which they are. (Except that I imagine the Nazi engineers may have been more directly employed by the Nazi government than LHM is by the US govt. That's just speculation though.)

"Nazi" refers to Nazi Germany as well as the party itself.
