Why not just librarian? Companies used to have their own libraries and librarians.

From what I have seen in software from similar iniativies:

If they are good enough at the subject matter to be useful they invariably get sucked into it the actual development effort.

So you end up with people who aren't and then it doesn't really work.

So it needs to be a portion of e.g. some developer's time, not a separate job/profession.
