RESPONSIBILITIES:

ESSENTIAL FUNCTIONS OF THE CLASS (May not include all duties performed.)

Performs the following leader work:

On a regularly recurring basis, leads personnel in HVAC task work while supporting their acquisition, or enhancement, of technical knowledge and skill on-the-job (OJT). Provides ‘targeted’ OJT and ‘opportunity’ OJT. Leads personnel, as assigned, in trainee/developmental level HVAC work to advanced level HVAC work, from routine and non-routine maintenance, diagnostics and emergency repairs of commonplace HVAC equipment and systems to journey, or higher, level diagnostics and modifications of rare or complex HVAC equipment and systems of APS. (Some equipment in use at APS may be rare in most workplaces and some systems in use at APS may be uniquely configured for APS.)

As a work leader, helps ensure safety of the work area and ensures that others, especially but not limited to those in one’s charge for the period of assignment, work safely.

Confers with the supervisor to learn the nature of work assignments and training needs, and to advise or consult on crew assignments, equipment to be used, and materials to be obtained or purchased. As assigned, supports the supervisor in assessing knowledge/skills of lower grade HVAC Mechanics and in identifying OJT and classroom training responses for knowledge/skill building purposes. (The range of knowledge/skill building OJT led, and classroom training provided may include introduction/acquisition, refresher/remedial, and advanced/superior, and typically varies based on progress in individual learning, introduction of new equipment/systems, advances in technology, including ‘green technology’, and other factors.)

Gives written or oral instructions, demonstrates techniques, and otherwise trains and coaches – some training/coaching may be accomplished by radio or phone; provides special instructions; and performs related training-communication-information functions, all as deemed necessary, or as required, to accomplish task work or to facilitate learning.

Prepares or collects and maintains or forwards associated documentation, such as attendance sheets and training logs. As assigned, completes formal SOJT (supervised OJT) job books to track specific items of individual learning and task work accomplishments in knowledge/skill building-oriented assignments and in daily, or as-required, tasks as they arise (which may facilitate learning, but are not inherently designed for learning).

Performs related leader work.
