What sort of options exist for running an organization's Nostr?

I am looking for what options I have for having a central npub through which delegate nsec's can publish notes, like a multi-sig sorta thing.

The idea:

one npub for an organization

multiple nsecs can publish through it via a managed service

Admin-type users can add-remove other nsecs from the service, so the main nsec is not shared amonst the authorized users, only "rented"
