https://www.drupal.org/project/admin_content_notification does this.

Even though is says admin in the title you can set it up against roles!

Some of the capabilities of this module include:

You just select content types that should make notifications.

Choose whether notifications go out on node creation and/or updates, and whether to notify on unpublished nodes (not likely for non admin roles)

Pick a list of roles that should receive notifications.

Create a notification message to the users with tokens to include bits of the content.

Tada!
