SENIOR MECHANIC TECHNICIAN
DEFINITION OF CLASS:
This is highly skilled work involving the provision of training in, and actual hands-on repair and preventive maintenance of a wide variety of heavy-duty vehicles, mobile, commercial transit, and/or fire/rescue apparatus and equipment. Contacts are with the crew/shift to which an employee is assigned, and involve observing and approving/correcting work performed, and providing instruction to individuals and groups of employees performing maintenance and repair work; with management to advise on training needed by individuals and groups of employees; and with manufacturers' representatives to discuss technical vehicle and equipment part and system problems. To a lesser degree, contacts also are maintained with supervisory employees from other shifts and work units to coordinate work efforts and pass on and receive information. This class of work may entail some public service/assistance, but it is incidental to the primary focus of the work performed.
An employee in this class, working under general supervision, is responsible for providing training, guidance and assistance to Mechanic Technicians and lesser-skilled employees in diagnosing and resolving difficult and unusual problems encountered in the maintenance and repair of heavy-duty vehicles, mobile and/or commercial transit equipment. Work involves observing and monitoring work performed; providing guidance, assistance and training; and responding to employees' maintenance/repair questions. An employee in this class checks, road tests and certifies vehicles and equipment as being both safe and having been properly maintained or repaired. Employees in this class will normally determine and recommend, within a prescribed value range, when a major component/assembly is to be repaired, rebuilt or discarded. The impact of the work of the class is the provision of expert training in vehicle and equipment repair and maintenance; guidance, assistance and support to Mechanic Technicians and lesser-skilled employees in the performance of their work; the provision of recommendations to management regarding individual and group training needs; and quality assurance in the repair and maintenance of a fleet of vehicles and equipment. Complexity of the work is derived from such factors as responding to and resolving the full spectrum of problems encountered in vehicle and equipment maintenance and repair; unavailability of parts and equipment; the analysis of costs to determine whether to repair or replace vehicles, equipment, parts and systems; and in determining whether alternative parts or systems meet or exceed originally planned ones. Employees are fully proficient, and proceed with assignments, which require planning of the work effort. This involves independently arranging the sequence of work, obtaining necessary materials and supplies, data and information, selecting the appropriate methods and procedures, and varying these as necessary in response to different situations. Guidelines, which cover most of the work performed, are available in the form of State and Federal laws which regulate vehicle safety and inspection programs; vehicle repair and maintenance manuals; warranty documents; and shop standard operating procedures. Employees occasionally develop new, or modify existing methods and procedures in order to improve effectiveness and efficiency. Approximately fifty percent of the work is performed in an office setting or in meeting rooms. The other fifty percent is performed primarily on the "shop floor" in a centralized maintenance/repair facility which exposes employees to drafts, changing temperatures, vibrations, dust, grease and noise. Working outside is generally limited to vehicle/equipment road tests or occasional emergency repairs. The most strenuous physical demands of this class of work, which are realized less than fifty percent of the time, involve lifting parts and equipment which weighs up to one hundred pounds. Assistance is usually requested in lifting heavier objects. Other physical demands involve extended periods of standing and walking throughout the shop; demonstrating methods and procedures, and assisting Mechanics and lesser-skilled employees in performing maintenance and repair work involving bending, stooping, reaching, stretching, climbing, and crouching. Hazards of the work involve occasional exposure to moving machinery and power tools, hazardous chemicals, blinding light and intense heat, and working at heights ten to twenty feet above floor level when on top of vehicles and equipment. Such work requires the strict observance of safety procedures and the wearing of protective clothing, masks, goggles, and steel-toed shoes.
