Agreed, maybe a bad example.

But a team of SWEs at different experience levels for the same role won't be different job descriptions.

I'm in this situation right now, I have a minimum requirement, it could be MET with someone with 1-2 years of experience or 20 years.

But that is the MINIMUM, if I find someone that meets that minimum but I get a lot more, I will pay more. But I'm still not making multiple job descriptions with different ranges.

Operational flexibility is a thing. A small company could be looking for competent and motivated people in general and adapt their internal processes to match the hire's experience level.
