Project role memberships are defined per project; however, there are cases where certain users or groups need to be members of a given project role by default. In fact, Jira has the following default members out of the box:

• Administrators: All members of the jira-administrators group
• Developers: All members of the jira-developers group

With these default members, users are automatically added to the project role when a new project is created; this greatly reduces the amount of manual work required from a Jira administrator.
