The work involves responsibility for performing journey level instrumentation work including the planning and laying out of work and the diagnosis of trouble in instrumentation systems or equipment as well as maintaining the SCADA system. An employee in this class frequently directs the work of a small number of skilled, semi‑skilled and relatively unskilled workers assigned to instrumentation maintenance and repair. Employees in this class are supervised by Instrumentation Crew leaders who prescribe priorities as well as the nature and extent of work to be performed, and the crew leaders provide diagrams and specifications as well as technical direction as needed. Employees in this class, in the absence of such direction, set priorities, determine work to be done, and lay out work with or without plans, diagrams, and specifications. The nature of work assigned and the skill level of an employee in this class call for employees to work with considerable independence. The nature of the work may require employees in this class to operate motor vehicles and power‑driven equipment. Does related work as required.
