After reading your qualifications on another thread you would probable be a Y-4. Now remember, most facilities hate to pay top wages to Engineers, since it isn't a money making area for them.
Good luck in your quest for higher wages.
For the sound editor/ designer pay,here is a link

The term sound designer does not have to increase an editors wage, but if they are good, they'll be working all the time.
Hope this helps,
