Bargaining unit(s): 207
Classification title: Transportation Generalist Senior
Function: Sign Maintenance
Kind of work: Intermediate technical, skilled work, and/or lead worker.

Nature & purpose

Under general supervision an employee in this class oversees difficult technical sign maintenance planning activities; provides ongoing, daily work direction to a sign crew in the installation, repair, or fabrication of signs to maintain the operational status of the sign program; performs related work as required.

This level is different from the Transportation Generalist in that at the Transportation Generalist Senior level, an employee initiates and/or prioritizes work activities, completes a variety of work assignments, chooses the methods in which to complete work using acquired knowledge of the function, and interpret Traffic Engineering Requests and Plans, including sign layouts and wind loading charts in the Traffic Engineering Manual, and apply them in the field.

An employee resolves semi-routine yet uncommon problems by searching for solutions learned from experience. Employees are responsible for completing multiple projects and/or work activities with competing deadlines and may set some priorities in the completion of work.
