Principal Engineer is L7 at a Amazon. So if that's the same as a Google L6 I guess the scales are a bit different.
As for L10, that's Distinguished Engineer. I think if they're managers they're also called VPs? I'm not exactly sure what the deal is there; but I know plenty of Amazon L10s who are fantastic engineers.
