At roughly $70/hr, this posting sits about 99% above the $35/hr median for welding jobs across New Jersey — toward the top of a $29–$40/hr middle band drawn from 114 postings with published pay. Put another way, it pays more than about 99% 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.
