How we know this
This job isn’t in the U.S. government’s occupational survey yet, so this page carries no official pay figures. Everything below is drawn from published job descriptions and industry guides, each one linked at the foot of the page. The work described is real and sourced. What’s missing is the survey’s rating of which parts of the job matter most — so read this as a picture of the work, not a ranked list.
