Perform environmental testing by operating and maintaining 39’, 7’x7’ and 10’x20’ thermal vacuum chambers all of which simulate and prepare satellites and their components forconditions in spaceLead, train and work with team to prepare, maintain and operate 39’ chamber and satellite during testingTroubleshoot and repair chambers during testing – issues regularly include: malfunctioning main cryogenic and/or liquid nitrogen pumps, municipal power and back-up generator outages, problems with thermal control unit (TCU), and solenoids freezingMaintain satellite within specified temperature tolerances during radio frequency (RF) and electrical testing Run bake-outs of chamber, sub-assemblies and cryogenic pumpsPrepare satellites for testing by performing oil changes on rough pumps, wiring of heater circuits, troubleshooting of auto thermocouples and corresponding thermocouples to specific heater circuits, checking for volts and amps on heater circuits, taking rough and final level of satelliteand creating temperature regulated zones in chamber
