There are no registration restrictions managed by the theme in relation to actual signup which actually uses the native WordPress user functionality. However, there are user registration types available (employer/job seeker), and depending on what you have set for resume viewing, you can restrict it to certain groups/paid users. You cannot restrict or limit viewing of jobs based on registration type though. This would either require customization on your part, or use of a plugin, however to clarify, AppThemes does not officially support third party plugins so we cannot guarantee they will definitely be compatible with our themes. Thanks.
