GENERAL DESCRIPTION OF CLASS

The INSTRUMENT TECHNICIAN 3 (MECHANICAL), under general supervision, designs, constructs, fabricates, repairs,
modifies, installs, and maintains original and innovative precision mechanical instruments, systems, or equipment
used for scientific and/or medical research. Incumbents typically perform original mechanical equipment and instrument
systems design under supervision from an Instrument Technologist (Mechanical) or professional engineer.

DISTINGUISHING FEATURES

This is the third level of a four-level series. It is distinguished from the higher level by the absence of
responsibility for independently designing complex state-of-the-art mechanical systems and for having a comprehensive
knowledge of system integration. It is distinguished from the lower levels by having the primary responsibility
to design equipment or units of a system that are not state-of-the-art or do not involve total system and integration.
Employees design original equipment from verbal requests, sometimes with very vague instructions from a scientific
faculty investigator. Designs require some adapting of existing precedents or techniques and the ability to exercise
originality based on an understanding of the interaction of various sub units in the system. Incumbents work with
a high degree of independence and are responsible for the technical quality and accuracy of their work.

DUTIES AND RESPONSIBILITIES

Under general supervision, incumbents perform all or many of the duties listed. Incumbents in this class are
expected to operate independently in the design, fabrication, construction, and maintenance phase of a major research
effort.

1. Design. Typical tasks: under general guidance by an engineer or scientific faculty investigator, employee
   designs from conceptual information equipment or units of a system that are not state-of-the-art or do not involve
   total system design and integration which are not commercially available; designs equipment modifications to original
   research instruments; designs new components to be integrated into existing laboratory instruments to adapt to
   changing needs as experiments evolve; makes drawings or blueprints of instruments to be constructed.
   
2. Fabrication of Instruments. Typical tasks: fabricates research instruments from own or other's drawings,
   blueprints, designs, or rough sketches. Selects most suitable materials to use in the fabrication of instruments
   and apparatus. Tests equipment to evaluate its performance and makes adjustments and modifications as needed. Uses
   all shop machines and test equipment such as precision lathes, milling machines, electrical discharge machines,
   tungsten inert gas welder, soft and hard solder, sheet metal shears and brakes, precision mechanical and electronic
   measuring instruments and mass spectrometer leak detectors.
   
3. Consultation. Typical tasks: consults with faculty researchers and staff regarding needs or technical
   problems relating to scientific instruments and equipment; writes work orders; estimates job completion dates and
   costs; provides consultation and recommendation on instruments to be purchased.
   
4. Instrument Maintenance and Repair. Typical tasks: performs calibration, alignment, preventive maintenance,
   diagnostic services, and repair of precision research instruments and equipment such as nuclear instruments, which
   are calibrated using radioactive sources such as cobalt 60 or radium, ultra high vacuum systems such as Molecular
   Beam Epitaxy System, laser systems, high resolution nuclear magnetic resonance, mass spectrometers, X-ray diffraction
   systems, and neutron generators; installs equipment and instruments following manufacturer's specifications; writes
   documentation and maintains records on repairs, calibration, and other work on equipment and instruments.
   

RELATIONSHIPS WITH OTHERS

Employees in this class are in regular in-person contact with physicians, academic researchers, staff, and students
while designing, fabricating, calibrating, and repairing scientific instruments and equipment. Employees are in
frequent contact by telephone or in person with vendors to purchase parts and with manufacturer's service representatives
to exchange information and to receive assistance on the assembly, repair, calibration, or exchange of instruments,
equipment, or parts.

SUPERVISION RECEIVED

Employees in this class receive general supervision from an instrument technologist, shop supervisor, or faculty
researcher. Design work is reviewed periodically at milestones and upon completion for adherence to design objectives.
Work is reviewed on an ongoing basis from feedback from researchers and staff as to whether instruments perform
well and are calibrated and repaired properly. Employees follow operator's manuals for the maintenance and repair
of instruments and standard scientific and mathematical principles in the fabrication of instruments.

MINIMUM QUALIFICATIONS

• Four years of instrument shop experience fabricating, modifying, repairing, installing, and maintaining scientific
  or medical instruments and equipment used in teaching or research. One year of the experience must have included
  performing basic design of less-complex systems and components; AND 
• One of the following: completion of a Machinist
  Apprenticeship program; or an Associate's degree in either Mechanical Engineering Technology or Machine (Manufacturing)
  Technology.
