About Parsons Corporation

Parsons Corporation cultivates an innovative culture focused on valuing people, embracing agility, and fostering growth. The company empowers its teams to achieve their full potential by working with exceptional individuals. Parsons is seeking a Traffic Signal Systems Expert to join its team in Riyadh, Saudi Arabia, for a full-time position.

Role Overview

The Traffic Signal Systems Expert will provide senior technical leadership for the assessment, planning, design, optimization, integration, operation, and performance monitoring of advanced traffic signal systems. This role supports a major urban traffic management program with a clear focus on measurable network performance. The expert will serve as the central technical authority for traffic signal systems across the program, ensuring that signal operations are safe, coordinated, data-driven, and operationally realistic.

Key Responsibilities

• Lead technical assessments of existing traffic signal systems, including controller hardware, cabinet configurations, detection systems, communications, central-system interfaces, timing databases, and operational procedures.
• Provide expert direction on adaptive signal control strategies, covering system configuration, operating parameters, corridor progression, congestion response, queue management, and performance monitoring.
• Review and optimize traffic signal timing plans, phasing sequences, cycle lengths, offsets, splits, clearance intervals, pedestrian timings, transit priority logic, and emergency vehicle preemption settings.
• Evaluate the performance of multiple signal control platforms and advise on their practical application, limitations, integration needs, and operational readiness within the agency environment.
• Lead the development of technical standards, guidelines, procedures, and checklists for traffic signal design, controller programming, detection placement, adaptive operations, signal maintenance, and field commissioning.
• Review traffic signal design packages, controller specifications, system architecture documents, testing plans, contractor submittals, and as-built documentation for technical completeness and operational suitability.
• Diagnose recurring signal operations issues, including split failures, detector failures, ineffective coordination, poor progression, excessive queues, and inconsistent controller settings.
• Define requirements for Automated Traffic Signal Performance Measures (ATSPM), high-resolution controller data, dashboards, alerts, and reporting tools that support continuous signal operations improvement.
• Work with ITS and systems integration teams to confirm that traffic signal systems properly interface with ATMS platforms, detection systems, CCTV/video analytics, AVL systems, traveler information tools, and incident response workflows.
• Support the implementation and tuning of public transport signal priority, Bus Rapid Transit signal operations, freight corridor coordination, pedestrian priority, and emergency vehicle preemption, balancing priority movements with overall network performance.
• Establish practical field testing, commissioning, verification, and acceptance procedures for new or modified signal installations, adaptive control deployments, detection upgrades, and central-system integrations.
• Lead technical workshops with agency staff, vendors, contractors, designers, operators, and maintenance teams to resolve signal system issues, confirm standards, and build consistent operating practices.
• Mentor client staff and project team members on traffic signal operations, adaptive signal concepts, controller logic, troubleshooting methods, performance analytics, and day-to-day TCC use of signal management tools.
• Provide input to project plans, risk registers, implementation schedules, quality reviews, and performance frameworks to ensure traffic signal system activities are properly planned, tracked, and delivered.
• Contribute to monthly, quarterly, and final reports by summarizing signal system progress, operational findings, risks, decisions, performance results, and recommended next actions.
• Act as a visible champion for proactive signal operations, helping shift the agency from reactive maintenance toward active, KPI-based management of the traffic signal network.

Collaboration and Technical Authority

This role requires close collaboration with traffic engineering, ITS, Traffic Control Center (TCC) operations, field maintenance, system vendors, and agency stakeholders. The expert will align traffic signal systems around a consistent, standards-based, and performance-driven operating model. The position involves guiding the agency towards active, KPI-based management of the traffic signal network.

Experience Requirements

Candidates for this position should possess 5 to 10 years of relevant experience in traffic signal systems. The role demands a strong technical background in the assessment, design, optimization, and operation of advanced traffic signal systems within urban traffic management programs.

Work Location

This full-time position is located in Riyadh, Riyadh, Saudi Arabia.
