Summary Description:
Under immediate (Mechanical Technician I) to general (Mechanical Technician II) supervision, performs a variety of skilled duties in the preventive and corrective maintenance, inspection, and servicing of mechanical equipment, components, machinery, and facilities associated with the production, pumping, storage, delivery and treatment of potable, agricultural, reclaimed water and wastewater; ensures compliance with general water discharge orders; operates a variety of light and heavy equipment and hand and power tools; and performs related duties as assigned.
Class Characteristics:
Mechanical Technician I: This is the entry-level classification in the Mechanical Technician class series. Initially under close supervision, incumbents learn and perform routine preventive and corrective mechanical maintenance duties. As experience is gained, assignments become more varied, complex, and difficult; close supervision and frequent review of work lessen as an incumbent demonstrates skill to perform the work independently. Positions at this level usually perform most of the duties required of the positions at the II-level but are not expected to function at the same skill level and typically exercise less independent discretion and judgment in matters related to work procedures and methods. Work is usually supervised while in progress and fits an established structure or pattern. Exceptions or changes in procedures are explained in detail as they arise.
Mechanical Technician II: This is the fully qualified journey-level classification in the Mechanical Technician class series. Positions at this level are distinguished from the I-level by the performance of the full range of duties as assigned, working independently, and exercising judgment and initiative. Positions at this level receive only occasional instruction or assistance as new or unusual situations arise and are fully aware of the operating procedures and policies of the work unit. This class is distinguished from the Mechanical Technician III in that the latter provides technical and functional direction to lower-level staff and is responsible for the more complex work.
Positions in the Mechanical Technician I/II class series are flexibly staffed; positions at the II-level are normally filled by advancement from the I-level. Progression to the II-level is dependent on satisfactory work performance (an overall performance rating of “exceeds standards” or higher on most recent annual performance evaluation is required), the incumbent meeting the minimum qualifications for the classification including any licenses and certifications, and management approval for progression to the II level.
