    • Experience with composite bonding and secondary assembly using structural adhesives
    • Ability to read and interpret engineering drawings, ply schedules, and work instructions
    • Proficiency with composite trimming, drilling, and finishing equipment
    • Familiarity with material handling requirements for prepreg and adhesive systems including out time and freezer control
    • Comfortable using hand tools, power tools, and basic shop equipment
    • Ability to lift up to 40 lbs and work standing for extended periods
    • Must be a U.S. Person as defined by ITAR
    • Periods of development may require long irregular hours around deadlines, including occasional weekends to support program milestones
