At roughly $57/hr, this posting sits about 71% above the $33/hr median for welding jobs across New Jersey — toward the top of a $28–$39/hr middle band drawn from 102 postings with published pay. Put another way, it pays more than about 93% of the comparable postings we have wage data for. Pay that far above local median usually comes attached to something: a harder cert requirement, travel, night shift, or overtime that isn't really optional. Worth establishing which before you accept.
