Under direction, to perform a variety of complex technical engineering duties in the field or office; to lead the work of lower level technicians on designated assignments; 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 3 is the advanced journey level in the series. Incumbents generally have independent responsibility for assigned projects, and may lead the work of lower level technicians on various projects. A professional engineer or higher level technician is available for consultation, significant problem solving, and review of completed projects. This classification is distinguished from the lower level Engineering Technician 2 which works with less independence and has limited crew chief responsibilities. It also differs from the higher level Engineering Technician 4 which performs the most complex technical or limited professional engineering duties, under the direction of a professional engineer.


Duties may include but are not limited to the following:

  1. Performs specialized technical inspection work; may lead the work of and train lower level technicians in the inspection of roads, bridges, drainage structures or traffic control devices under construction or improvement.
  2. Performs land surveys; may lead the work of and train lower level technicians in the survey of existing and proposed roads, bridges, traffic control and drainage structures; determines field control techniques for property boundary surveys; measures angles and elevations; assembles survey information including computations, maps, property descriptions and specifications to determine project or program requirements; operates or instructs in the operation of survey instruments and electronic data collection equipment; investigates and researches the recovery of obscured or lost original land corners.
  3. Schedules, coordinates, and reviews work of assigned drafting staff; performs complex technical manual or computer-aided design work; performs records research, advanced geometric computations, triangulations and adjustments; prepares survey data for electronic data processing; verifies completion and accuracy of plat maps for new subdivisions, annexations, easements, or changes in boundaries or facilities for local improvement districts.
  4. Assembles project or program records, including computations, maps, legal property descriptions, and specifications; keeps detailed records for maintaining and perpetuating legal land documents; writes and reviews routine legal descriptions for rights-of-way, easements, annexations, and subdivisions.
  5. Prepares survey and engineering data for assigned project or program; develops technical reports and feasibility studies; computes bid quantities, writes specifications and estimates costs; reviews contracts of outside contractors.


Thorough knowledge of: Principles and practices of land surveying, including operation of survey instruments; engineering plans, specifications and mathematics; drafting instruments, materials and techniques.

Working knowledge of: Practices of civil engineering design; methods and procedures of testing of roads, bridges, drainage structures and related construction materials; basic hydrology; principles of traffic and engineering and conveyances; applicable laws, rules, regulations and ordinances; technical report writing; principles of lead work supervision; microcomputer software relating to engineering drafting and designing; English grammar and composition.

Skill to: Communicate effectively, both orally and in writing; make complex mathematical calculations with speed and accuracy using fundamentals of algebra, geometry and trigonometry; prepare detailed and precise construction drawings; conduct complex title and property ownership research; prepare and interpret complex legal descriptions and other legal documents; supervise or execute microcomputer applications in drafting, designing and engineering data collection; lead, train and review the work of lower level technicians; 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 3 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.
