There is likely no engineer at that level, instead they're gaming the law. They're required to report their salary range for transparency, and they're basically replying with "our salaries are between between 0 and $1M".
Don’t expect more than 40 hours per week though. It’s not like you’re paying me the big bucks that Mike is getting.
EDIT: On a serious note, I’d be all over this if they offered remote, but if they did they’d not offer nearly as much.
