Under direction, to perform the most complex and responsible technical or limited professional engineering duties in the field or office; to lead the work of lower level technicians; and to do other work as required.


The Engineering Technician series is primarily oriented to performing technical engineering functions to assist in the design, construction and maintenance of public works projects such as roads, bridges, traffic control, street lighting, land monuments, storm drains, sanitary sewer systems and treatment facilities. Positions in this series work under the supervision or direction of an advanced level technician or professional engineer. Individual assignments are generally limited to a particular specialized area, and involve basic engineering knowledge and skills gained through work experience or training programs.

This series is distinguished from professional engineering classifications which require professional certification, registration or licensure, as well as broad general professional knowledge of engineering principles and practices applicable to a variety of complex engineering projects or areas.

The Engineering Technician 4 is the highest level in the series. Positions at this level are assigned functional supervision of a work unit or function within an area of specialization, such as computer aided design systems, road surveying, design review or traffic operations. Incumbents serve as project leaders, resolving technical problems, coordinating professional and technical staff, and making recommendations involving the most complex technical or limited professional engineering duties. The Engineering Technician 4 works independently under the general direction of a professional engineer. This classification is distinguished from the higher level Civil Engineer, Associate which is responsible for performing moderately complex professional engineering work in the planning, design, construction, and maintenance of public works or related projects and licensed as an Engineer-in-Training. The Engineering Technician 4 is distinguished from the lower level Engineering Technician 3 which is assigned responsibility for specific projects rather than a functional work unit or system.


Duties may include but are not limited to the following:

  1. Schedules, coordinates and reviews the work of lower level technicians in the preparation of engineering and construction plans and drawings, surveys, and technical reports; establishes and maintains standards for assigned project or program; reviews final plans to ensure compliance with contract specifications and county, state and federal requirements; prepares detailed estimates of costs, materials, labor and equipment; writes progress reports and coordinates advance and final payments to contractors; oversees preparation of final records.
  2. Under the guidance of a professional engineer, designs or makes modifications to designs or standards to meet local conditions; serves as project leader on minor projects and for technical systems related to engineering; confirms controlling elements of property boundaries; recovers obscured or lost original land corners; writes and reviews special provisions for contract specifications.
  3. Prepares and oversees the preparation of maps, legal descriptions, documents and exhibits to be used to evaluate land boundaries, rights-of-way, easements, annexations, and subdivisions; reviews related maps and legal documents prepared by subordinates for accuracy and clarity; confers with professional surveyor for assistance on complicated survey issues; coordinates work with other interested agencies, departments and contractors.
  4. Inspects or oversees the inspection of final construction work on complex projects for developing or improving roads, bridges, drainage structures and traffic control devices; directs the work of lower level technicians in performing inspection work to insure compliance with contract specifications.
  5. Develops procedures for conducting engineering studies and supervises the collection and reporting of data; ensures the preparation of necessary reports, records, and correspondence.
  6. Performs the most difficult technical functions to ensure the most appropriate control devices and safety precautions are utilized for conformance to existing standards, and to recommend changes if necessary; assigns projects to subordinate technicians, provides training and assistance with computer design systems and applications, reviews their work for completeness, accuracy and conformity to accepted engineering practices and other legal requirements.


Thorough knowledge of: Principles and practices of land surveying, engineering plans, specifications and mathematics; methods and procedures used in the testing of roads, bridges, drainage structures and related construction materials; drafting instruments, materials, methods and techniques.

Working knowledge of: Principles of civil engineering design; principles of hydrology, construction and inspection techniques; applicable laws, rules, regulations and ordinances; concepts of traffic engineering and control; technical report writing; principles of lead work supervision; microcomputer applications relating to engineering practices; advanced CAD systems, software, and applications; English grammar and composition.

Skill to: Communicate effectively, both orally and in writing: read and interpret engineering drawings, maps, plans, specifications and related legal documents; lead, train and review the work of lower level technicians; perform difficult mathematical calculations; perform precise engineering measurements; write clear and concise technical reports and correspondence; collect, analyze, and make sound recommendations based on principles and practices in the field of civil and traffic engineering and land surveying; establish and maintain effective working relationships with subordinates, the public, contractors and County personnel.


Field activities include moderately strenuous physical work and incumbents may encounter adverse environmental conditions such as inclement weather and traffic hazards.

Within DTD Engineering Division, duties require frequent standing, walking, squatting, bending, kneeling, reaching, digging, balancing, fine motor control, and the ability to lift and carry up to 60 pounds, push 50 pounds, and pull 70 pounds. Duties also involve frequent exposure to loud noises, vibration, slippery and/or uneven surfaces, exhaust fumes and dust, oil and chemicals, traffic hazards, and adverse weather conditions.

Within DTD’s County Surveyor’s Office – Public Land Corner, duties in the field require frequent walking, stepping, squatting, kneeling, bending, twisting, digging, swinging, balancing, grasping, fine motor control, and the ability to lift and carry up to 90 pounds, including carrying 60 pounds on one shoulder. Duties also involve frequent exposure to slippery and/or uneven surfaces including steep terrain, loud noises, vibration, exhaust fumes and dust, and adverse weather conditions.


Some positions must successfully pass a criminal history check which may include national or state fingerprint records check.

Driving may be necessary for County business. For position(s) with occasional/incidental driving, incumbents must possess a valid driver's license. Accommodation requests for an acceptable alternative method of transportation will be reviewed on an individual basis in compliance with State and Federal legislation. For position(s) with regular driving, incumbent(s) must also possess and maintain an acceptable driving record throughout the course of employment.

Within DTD Engineering Division and DTD’s County Surveyor’s Office – Public Land Corner, employment is contingent upon passing a post-offer physical assessment. Accommodation requests will be reviewed on an individual basis in compliance with State and Federal legislation.


Any satisfactory combination of experience and training that demonstrates possession of the required knowledge and skills.


The Engineering Technician 4 is part of a promotional career path within Water Environment Services Department. Incumbents in the Engineering Technician 3 classification may be promoted to open positions in the Engineering Technician 4 classification upon satisfactory completion of an approved training and development plan. Possession of the required knowledge, skills and abilities at the higher level must be documented in an approved promotional evaluation.
