Pneudraulic Systems Mechanic
Federal Wage Grade position maintaining, troubleshooting, and repairing pneumatic and hydraulic systems on industrial equipment, vehicles, and aircraft at federal facilities and military installations.
What WG-8255 pays
Federal Wage System pay is set by local prevailing wage surveys, so it moves with the wage area rather than a national table.
Wage Grade rates are published per wage area rather than nationally, so the number that matters is the one for the installation you are applying to.
