<< Classified Job Listing

Class Code: 530M
Category: Science & Engineering


Performs advance transportation engineering work under limited supervision.

Distinguishing Characteristics

At this level, incumbents are generally placed in charge of a major project or functional area which is characterized by supervising several support staff (staff may include or consist of contracted consultants) or serve as a staff specialist in a complex area of limited scope (this may include serving as a staff specialist consultant to Local Agencies). Incumbents are expected to possess a thorough working knowledge of agency policies, standards and procedures as well as engineering principles, methods and practices. Assignments require judgments in selecting and adapting techniques to solve transportation problems. Incumbents may represent the Department at public meetings, open houses, to local agencies, contractors, consultants, etc., for specific projects. While work is occasionally spot-checked and reviewed upon completion, incumbents are responsible for planning and carrying out projects with only minimal supervision. Staff at this level are often called on to assign, train and evaluate engineers and technicians.
