Job Description

Parsons is seeking an amazingly talented Transport & Mobility Staff Engineer - Saudi National to support a significant transportation project in Riyadh Saudi Arabia, contributing to the assessment of the city's road mobility network and the development of strategies, plans, and design improvements that enhance mobility and safety.

You will work with guidance from senior staff but with minimal day-to-day instruction on assigned tasks, delivering a range of technical outputs including traffic and safety studies, field investigation reports, concept plans, guidelines inputs, and operational analyses. Your work will span traffic signal operations, signing and pavement markings, transportation safety, multimodal considerations, and intelligent transportation systems, supported by a sound understanding of roadway and traffic design principles.

What You'll Be Doing

Support network, corridor, and intersection assessments, including capacity, delay, queueing, and basic safety reviews for key arterials, intersections, and expressway ramps.
Conduct and document field investigations, including site observations, inventory of existing traffic control devices, and identification of operational and safety issues.
Assist with transportation safety analyses, including review of crash data, conflict points, and roadside conditions, and help develop practical countermeasure concepts.
Prepare and update traffic signal timing inputs, phasing diagrams, and coordination concepts under the direction of senior traffic engineers.
Develop draft concepts for traffic signing and pavement markings, lane-use arrangements, and channelization layouts consistent with applicable standards and client preferences.
Support pedestrian and vulnerable road user assessments, including observations of crossing behavior, review of pedestrian facilities, and checks of pedestrian timing and accessibility.
Apply roadway and traffic design principles when assisting with concept designs for intersection and corridor improvements, ensuring operational and safety considerations are reflected.
Assist in the evaluation of ITS-based solutions (e.g., detection, CCTV, traveler information, enforcement technologies) from an operational viewpoint, including data needs and expected benefits.
Perform traffic operational analyses using appropriate tools and datasets, and help summarize results to support recommendations for optimizing traffic operations.
Contribute to the preparation of technical materials such as traffic and safety study sections, concept plan notes, guideline inputs, and draft technical specifications for agency review.
Support the preparation of figures, exhibits, and presentations for technical reports, stakeholder meetings, and decision forums.
Participate in internal and client review sessions to explain findings, capture comments, and refine recommended solutions.

What Required Skills You'll Bring

Bachelor's degree in Civil Engineering, Transportation Engineering, Traffic Engineering, Urban/Transport Planning, or a closely related field.
Minimum 2 years of practical experience in traffic engineering and transportation, preferably including work with or for public transportation/road agencies.
Foundational experience across key areas of traffic engineering, such as traffic signal operations, signing and pavement markings, intersection and corridor operations, and safety-focused improvements.
Demonstrated exposure to transportation safety work, including field observations, basic crash analysis, and identification of operational and infrastructure risk factors.
Practical experience performing field investigations and documenting existing roadway, traffic control, and user conditions in a clear and organized manner.
Understanding of roadway and traffic design principles (e.g., basic geometric design, turn lanes, sight distance, crosswalk placement) and how they influence operations and safety.
Exposure to intelligent transportation systems and technology-enabled strategies for monitoring, managing, and improving traffic operations.
Experience preparing technical materials such as traffic or safety study inputs, concept-level plans, design notes, and draft guideline or specification content.
Competence in using traffic engineering and analysis tools (such as Synchro, SIDRA, HCS, or similar) and working with traffic data to support operational assessments.
Strong written and verbal communication skills in English, with the ability to explain technical observations and recommendations clearly to both technical and non-technical stakeholders.
Ability to work effectively in a multi-disciplinary, multi-cultural environment, managing priorities across several assignments in a program setting.

What Desired Skills You'll Bring

Experience supporting large metropolitan or national transportation agencies on traffic engineering, road safety, or traffic management programs.
Familiarity with international and regional roadway and traffic engineering standards and guidance, and the ability to apply them in concept-level work.
Field experience supporting road safety audits, corridor safety reviews, or work zone/temporary traffic management assessments.
Ability to work effectively in both field and office environments.
Organized and attentive to detail, with the ability to document complex technical procedures.
Team-oriented, collaborative, and comfortable working under the direction of senior system engineers and developers.
Proficient in Microsoft Office Suite and able to learn specialized configuration tools quickly.
Progress toward professional registration/certification (e.g., EIT, PE track, CEng track, PTOE, or equivalent) is an advantage.
Communication skills in Arabic are desirable but not required. Strong analytical, troubleshooting, and technical problem-solving skills.
