About Parsons and the Role

Parsons Corporation is seeking a Traffic Signal Operations Engineer to join its team in Riyadh. This full-time role focuses on supporting the day-to-day operational performance of signalized intersections and corridors within the city. The position requires 5-10 years of relevant experience.

Role Overview and Objectives

The successful candidate will be responsible for monitoring traffic conditions, reviewing signal phasing and timing, identifying deficiencies, and implementing approved timing improvements via the traffic signal control system. This role is integral to transitioning signal management from a reactive approach towards continuous, data-driven performance improvement across Riyadh's road network.

Key Responsibilities

• Monitor signalized intersections and corridors using the traffic signal control system, CCTV, performance dashboards, detector information, field observations, and other operational data.
• Review signal phasing, sequence, splits, cycle lengths, offsets, clearance intervals, recalls, detector settings, and controller operating parameters to identify operational issues and improvement opportunities.
• Develop and implement approved traffic signal timing adjustments for isolated intersections and coordinated corridors under established change-control procedures.
• Conduct before-and-after observations to confirm that timing changes improve queues, delay, progression, throughput, and overall traffic operations without creating unacceptable secondary impacts.
• Support corridor progression and green-wave optimization through review of offsets, travel times, platoon movement, and coordination plans.
• Identify split failures, excessive queues, wasted green time, poor detector operation, coordination breakdowns, recurring congestion, and other signal-performance deficiencies.
• Utilize ATSPM and high-resolution controller data, where available, to evaluate arrivals on green/red, phase utilization, split performance, and detector activity.
• Coordinate with field maintenance teams regarding detector failures, controller faults, communication problems, cabinet issues, or other equipment conditions affecting traffic operations.
• Support adaptive signal operations by reviewing system performance, verifying controller and detection inputs, and escalating abnormal behavior to the appropriate specialist.
• Assist with the implementation and monitoring of special-event plans, incident-response timing plans, emergency vehicle preemption, and transit signal priority.
• Maintain clear records of timing changes, operational observations, reasons for intervention, approval status, and measured outcomes for shift handover and future reference.
• Conduct field visits during peak periods to validate system observations and identify operational issues not evident from central monitoring tools.
• Support the development of standard timing practices, signal operations procedures, corridor playbooks, performance thresholds, and TCC operational documentation.
• Provide technical support and knowledge sharing to TCC operators and junior traffic engineers on signal operations and controller behavior.
• Participate in regular signal-performance reviews and recommend locations requiring more detailed engineering analysis or geometric improvement.

Collaboration and Teamwork

The Traffic Signal Operations Engineer will work closely with senior signal timing engineers, adaptive/ATMS specialists, TCC operators, field technicians, and RCRC engineers. This collaborative environment is crucial for effective signal management and continuous operational improvement.

Required Experience

• A minimum of 5 to 10 years of experience in traffic signal operations or a related field.

Location and Work Type

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