Nurse Informatics

Hi Everyone,
Does anyone know of companies that hire entry level nurse informatics? I am thinking about going back to school for my Masters but am also trying to break into the field to start getting some experience. Any suggestions?
I have never seen any 'entry level' Informatics positions. All nurse informaticists I know have pretty much the same career trajectory .... became the 'superuser' or 'go-to' person with their own EHR. They stood out from the crowd, were offered/asked to train co-workers --> moved into an IT/informatics role. Most chose to get Informatics certification - I only know 2 that got an MSN in CI. Even without grad degrees, they are making very good salaries.
Thanks for the info! I actually have been the superuser in a previous job and was on the Informatics council. I am trying to break into the field, but when I apply for jobs I don't get call backs for more IT type positions. I am considering going back to school now.
