For the skillset being asked, if you ignore the equity component (as I'm guessing GP did), $130k is absurdly low anywhere in the US. Folks in many metro areas (Portland, Austin, Phoenix, etc) with the desired XP and skillset can easily make $250k cash salary + $50k highly liquid public equity at major companies (Intel, Samsung, Globalfoundries, etc).
Anyone with that XP concretely applying those skills at most commercial fabs is easily creating millions of dollars of value (as a portion attributable to their contribution to the overall fab's value creation); if at all, it's absolutely insane that they get compensated so little on average.
