If you go to local competitions, you might see more familiar skaters on tech panels and as judges. But it takes several years to get through the levels to a point where the national federation would consider nominating an official for ISU appointment. I would expect that most of the Big Name Current Competitors are too busy skating and training to take the time to train as an official.
The USFS website has information on how to become an official, if you want to get an idea of how these people started.
