Non-Teacher Faculty are definitely allowed but are still subject to the log requirements (you could be a janitor but would still need to run a log of some sort). That said, it is unlikely that a being who is two hundred years old would be a total master in magic, especially with the broad ranges of disciplines Daybreak teaches. They would still have SOMETHING to teach, and grad would be fairly appropriate as they can really define their own schedule and course load.
