CADD Designer – Traffic Signal Plans

In a world of possibilities, pursue one with endless opportunities. Imagine Next!   At Parsons, you can imagine a career where you thrive, work with exceptional people, and be yourself. Guided by our leadership vision of valuing people, embracing agility, and fostering growth, we cultivate an innovative culture that empowers you to achieve your full potential. Unleash your talent and redefine what’s possible.   Job Description: Parsons is looking for an amazingly talented CADD Designer – Traffic Signal Plans to join our team! In this role, you will develop and maintain accurate traffic signal layout drawings, intersection base plans, controller and detection information, and as-built records that support traffic engineering and Traffic Control Center operations across Riyadh. You will work closely with traffic signal engineers, Synchro modelers, roadway engineers, ITS specialists, field inspectors, and TCC staff to ensure that the drawings used for operational analysis and signal management accurately reflect current field conditions and approved changes. What You’ll Be Doing: Prepare, update, and maintain CADD traffic signal layout plans for signalized intersections and coordinated corridors. Develop accurate intersection base drawings showing roadway geometry, lane assignments, stop bars, crosswalks, signal poles, signal heads, pedestrian equipment, cabinets, detection zones, communications elements, signs, and relevant pavement markings. Update existing signal drawings using field survey information, redlines, photographs, controller records, construction drawings, and verified as-built information. Prepare and maintain as-built traffic signal plans used by traffic engineers and TCC staff for operations, timing development, troubleshooting, and future modifications. Coordinate drawing information with Synchro models so that lane geometry, approach configurations, signal phasing references, and intersection identifiers remain consistent between operational models and signal plans. Prepare signal phasing diagrams, detector layouts, cabinet/equipment schedules, pole and head identification, and other supporting plan information under engineering direction. Incorporate approved traffic signal timing, phasing, geometric, detector, and field-equipment changes into controlled drawing sets. Support development of corridor plan sets and location maps showing groups of intersections used for traffic signal management and progression studies. Conduct or support field verification activities to resolve discrepancies between legacy drawings, central-system records, and actual site conditions. Maintain drawing revision history, file naming, layer conventions, title-block information, document numbers, and issue status in accordance with project CADD and document-control standards. Perform drawing quality checks for completeness, legibility, dimensional consistency, symbols, references, layer use, and conformity with approved drafting standards. Coordinate with roadway and ITS designers where signal modifications interact with geometric improvements, communications infrastructure, detection, power, or other roadside systems. Produce clear PDF plots and editable CADD files suitable for engineering review, RCRC submission, field use, and final handover. Assist with preparation of sketches and exhibits for traffic improvement concepts, technical reports, presentations, and implementation packages. Organize and maintain the traffic signal drawing library so that engineers and TCC personnel can reliably retrieve the current approved or verified as-built plan for each intersection. What Required Skills You’ll Bring: Diploma or associate degree in Civil Engineering Technology, Drafting, CADD, Transportation Technology, or a closely related discipline. 5+ years of CADD design/drafting experience on roadway, traffic signal, ITS, transportation, or civil infrastructure projects. Strong proficiency with AutoCAD and/or MicroStation and demonstrated ability to prepare accurate engineering plan drawings from technical direction and field information. Experience preparing traffic signal, roadway, electrical/ITS, utility, or comparable infrastructure drawings; direct traffic signal plan experience is strongly preferred. Ability to read and interpret engineering plans, roadway geometry, signal phasing information, equipment layouts, field redlines, and as-built documentation. Strong attention to detail and ability to identify discrepancies between drawings, model information, records, and field conditions. Working knowledge of CADD layers, references, blocks/cells, annotation, plotting, title blocks, revision control, and file-management practices. Ability to coordinate with engineers and incorporate technical comments accurately and efficiently. Good organizational skills for maintaining large numbers of intersection drawings and revision records. Working proficiency in English sufficient to understand technical comments, drawing notes, and project standards. What Desired Skills You’ll Bring: Previous experience preparing traffic signal layout and as-built plans for a Traffic Control Center or citywide signal-management program. Familiarity with Synchro network geometry and the information needed to keep operational models aligned with signal drawings. Experience with Civil 3D, OpenRoads, GIS, ProjectWise, or other engineering design/document-management platforms. Knowledge of traffic signal equipment, detection systems, controller cabinets, communications, signal poles/heads, and pavement markings. Previous project experience in Saudi Arabia or the GCC is desirable. Arabic language skills are desirable but not required. Parsons equally employs representation at all job levels no matter the race, color, religion, sex (including pregnancy), national origin, age, disability or genetic information.
