The Opportunity: Transportation Engineer (Traffic Modeling)

SYSTRA is seeking a seasoned Transportation Engineer specializing in Traffic Modeling to join its team in Makkah, Saudi Arabia. This full-time role involves leading traffic and mobility studies across complex urban and corridor environments. The successful candidate will guide end-to-end modeling workflows, translate technical outputs into actionable recommendations, and support critical planning, design, and operational decision-making for both public and private sector clients.

Key Responsibilities

• Lead the development, calibration, and validation of multi-scale traffic models, including VISUM for strategic demand and network assignments, and VISSIM for detailed operational simulations.
• Establish modeling methodologies, QA/QC protocols, and scenario frameworks aligned with local standards and international best practices.
• Define data requirements, oversee data collection plans, process and reconcile multi-source datasets, and apply rigorous calibration and validation procedures using KPIs such as GEH, V/C, delay, and travel time reliability.
• Build and assess scenarios covering masterplans, land-use changes, network enhancements, transit priority, ITS strategies, demand management, and construction traffic management.
• Evaluate performance using metrics like LOS, queues, person-throughput, emissions/energy proxies, and reliability, generating clear, decision-ready insights and mitigation strategies.
• Interface with roadway and transit design teams to test geometric alternatives, signal control strategies, bus priority, and multimodal operations.
• Prepare signal timing plans, coordinate with control center and authority stakeholders, and support temporary traffic management and staging plans.
• Engage with client authorities, developers, and multidisciplinary teams to define objectives, present findings, and secure approvals.
• Produce high-quality technical reports, executive summaries, and visualizations that convey complex modeling results to both technical and non-technical audiences.
• Apply KSA/GCC authority guidelines and international references (HCM, ITE, MUTCD, PIARC) where applicable.
• Contribute to internal standards, templates, and knowledge sharing, and mentor junior modelers and engineers.

Required Qualifications and Experience

• Bachelor’s degree in Civil/Transportation Engineering or a related field; a Master’s degree is preferred.
• A minimum of 10 years of professional experience in transportation planning or traffic engineering, with a strong modeling focus.
• Proven, hands-on expertise in PTV VISUM (strategic/macroscopic) and VISSIM (microscopic), including calibration, validation, and scripting/customization.
• Demonstrated experience delivering studies in Saudi Arabia or the GCC region, with familiarity in local authority processes and approvals.
• Strong command of traffic engineering principles, including capacity analysis, LOS, signal operations, roundabout analysis, safety fundamentals, and multimodal integration.
• Experience in projects involving master planning, corridor studies, interchange/junction design, BRT/LRT/metro interface assessments, and work zone planning.

Technical Skills and Expertise

• Advanced proficiency in VISUM and VISSIM, encompassing network coding, demand modeling, signal control, transit modeling, and queue/spillback analysis.
• Working knowledge of related tools such as SIDRA, Synchro/SimTraffic, HCS, or Aimsun (desirable).
• Proficiency in scripting and automation for modeling workflows using Python, COM/.NET APIs for PTV tools, and data processing with GIS (ArcGIS Pro) and Spatial SQL.
• Experience with data pipelines, including surveys, Bluetooth/FCD, OD estimation, matrix estimation, and sensor integration.
• Exposure to Intelligent Transportation Systems (ITS) planning, adaptive signal control, and operations analytics using control center data.
• Familiarity with emissions and sustainability impact assessment methods and KPIs.
