In terms of private services the two biggest players in the Austin area are Acadian and AMR, there are a few other smaller companies out there, but for the most part, the industry has been consolidated. Acadian has the Seton transfer contract and AMR has the St David's transfer contract, I don't know much else beyond that. Both companies have some 911 contracts in the surrounding areas, but from my understanding speaking with privates, the "911" trucks still do transfers. Travis, Williamson and Hays county (the three most populous counties in the area) all use some form of government run EMS services so you won't be running 911 there.
Unlike most of California, you can make base contact with any hospital, privates use cell phones while we (county EMS) use UHF radios to make contact.
University Medical Center Brackenridge (commonly called Brack) is only adult Level I trauma center in the Austin area, but there are three Level II trauma centers in the area, they are located St David's South Austin (just got certified), Round Rock Medical Center and Seton Medical Center Williamson.
For kiddos you have Dell Children's Medical Center as a pediatric level I trauma center and St David's Children's Hospital (located in North Austin Medical Center), which doesn't take trauma at this point.
There are four Comprehensive Stroke Centers (Brack, Austin Heart Hospital, Seton Main and St David's Main) and a bunch of Primary Stroke Centers (too many to name).
There are also a ton of STEMI Centers, off the top of my head I can think of at least 10 in Travis and Williamson Counties alone.
No burn centers in the area, the closest one is in San Antonio at SAMMC.
Job wise, I would recommend putting in your time at AMR while applying to 911 services or while you go through medic school.
Good luck and welcome to the 512.
