Are Post-Docs considered "faculty"?

[goddess_gaia]

I need a faculty member to be a second reader for my undergraduate thesis. Are post-docs considered to be faculty members?
It might help to add that my director (or primary reader) is a professor. I am looking for a second reader, who needs to be a faculty member. The third reader can be a grad student. It seems that post-docs fall into a hole between 2nd and 3rd capabilities?

In most facilities post-docs are not considered faculty. My "most" I mean I'm unaware of an exceptions.
