  Description
  The Engineering and Compliance Division is seeking two (2) highly motivated, organized and detail-oriented Air Quality Engineers.
  An Air Quality Engineer performs a variety of professional engineering work in connection with evaluation, control, monitoring, and assessment of air quality standards, conditions, plans and strategies to ensure public and private compliance with applicable laws, rules and regulations; and performs other related duties as required.
  DISTINGUISHING CHARACTERISTICS:
  Assistant Air Quality Engineer - The entry level class in the professional air quality engineering series. Incumbents are responsible for office and/or field projects of average difficulty and complexity and are required to direct them to completion. Assistant Air Quality Engineers have no supervisory responsibility but do provide technical direction to others. Incumbents are expected to demonstrate increased proficiency and knowledge and work under less supervision during the training period. Incumbents are gradually given more difficult and responsible assignments and may assist experienced staff on more difficult projects.
  Associate Air Quality Engineer - The fully experienced, journey level professional engineering class in the series who performs difficult and complex engineering work under general supervision. Incumbents provide technical guidance or training to other staff or may act as a project leader.
  Positions in this class are flexibly staffed and are normally filled by advancement from the lower grade of Engineer Specialist, or when filled from the outside, require prior engineering experience.
  Assistant Air Quality Engineer
  
  Pay Range: $46.24 - $56.20/hour with typical starting pay between $46.24 and $50.98/hour*
  
  Associate Air Quality Engineer
