Texas and Florida have software engineer P.E. according to: https://en.wikipedia.org/wiki/Regulation_and_licensure_in_en...

I think there are a couple of states where you are not allowed (by law) to use engineer unless you are a P.E. but there are industrial exemptions, which muddy the waters. As compared to "Professional Engineer", which is don't use it if you don't have a license in the U.S. state where you are offering engineering services.
