Jobs and businesses are not in the buddypress coding.
If you meant business as in a user profile administrating different capabilities like regular posts, custom posts and Buddypress groups, then WordPress itself has the means.
You can upgrade any user account as a site administrator to become, for example, an editor or author with more capabilities than a normal account.
In a Buddypress group you can manage who’s the groups administrator inside the group under “manage”.
