  • Utilizes a broad skill level of a mechanical, hydraulic, electrical, and electronic in nature tools to repair and maintain most shop equipment.
  • Must be able to set-up and fabricate machine components on lathe, drill press, grinder and other metalworking tools to make and repair parts.
  • Inspects used parts to determine changes in dimensional requirements using rulers, calipers, and micrometers.
  • Fabricates, assembles, and tests parts using a complete range of mechanical hand and power tools including precision measuring devices, instruments, and gauges, metal fabricating tools and welding torches.
  • Responsible for the preventative maintenance, installation, and/or repair of equipment through varying trade disciplines, using computer systems, as well as cross-functional responsibility as a Maintenance Machinist.
  • Collaborates with other departments during capital purchasing decisions by offering researched opinions in cost effective approaches to machinery/equipment selection and functionality.


  • Perform preventative maintenance and calibration of equipment and systems throughout the facility.
  • Analyzes, identifies, and corrects mechanical faults of improperly operating or inoperative machinery through varying trade and/or mechanical processes.  Diagnoses mechanical problems by instrumentation, sound and visual observation and determines how best to resolve the problem by checking blueprints, repair manuals, parts catalogs drawing and from experience and expertise.
  • Inspects work of Maintenance Mechanics I & II to assure proper installation, maintenance, and repair of equipment.
  • Tests and runs-off machines to ensure proper operation and correction of the identified problem. 
  • Records maintenance and repair work performed and the duration of time used per work order. Maintains equipment, parts and supplies inventories by checking stock to determine inventory level; anticipating needed equipment, parts, and supplies.
  • May be responsible for Lockout/Tagout (LOTO) or the specific practices and procedures to safeguard employees from the unexpected energization or startup of machinery and equipment.



  • High school diploma or general education degree (GED) along with related trade school education, apprenticeship and/or experience.
