  • Operate related shop equipment, hand tools, and measuring instruments.
  • Provide general technical support for a wide variety of activities, including vacuum, electrical, pneumatic, and plumbing/cooling installations.
  • Derive technical information from sketches, drawings, verbal, or written instructions, and subsequently solve fit, interference, and functional electro-mechanical problems.
  • Use advanced methods to acquire and analyze basic data and test results using known performance parameters to report results and identify problems.
  • Produce supportive documentation and graphics using drafting, design, engineering, and scientific programs on computer systems.
  • Perform preventative maintenance procedures including machine chemical changes.
  • Perform other duties as assigned.

Additional job responsibilities, at the 533.3 level

  • Independently deploy, fabricate, troubleshoot, assemble, and disassemble complex electro-mechanical components and systems, including planning and selecting materials, equipment, and methods.
  • Assist in developing test parameters, troubleshooting, and testing materials, components, or systems, identifying problems, and providing input on solutions.
  • Independently identify, analyze, evaluate, and report results to complex electro-mechanical problems using individual creativity and judgment; prioritize and provide work and technical guidance to others, checking for accuracy, completeness, and function.
