the lottery is wage-weighted — each level is one more entry
$7,986 more — $112,986 — moves this role to Level II and 2 lottery entries. That figure is inside the range the employer already advertised.
Based on the DOL prevailing wage for this occupation and worksite, a base salary of $112,986 would place this position at wage Level II. That figure is within the posted range, and I'd like to target it. This role classifies under "Materials Engineers" for prevailing-wage purposes.
