Having issues with user permissions

basically want to set up a user to help manage minecraft server

Things I want them access too
Backups
Start/Stop/Restart
Console

Thats it

Things they keep get access too
Usermanagement

Things ive tried
Setting user permissions directly rather then roles
Setting up roles for user
