Parsons; Riyadh; On-site; SAR 156,000 - 234,000; Full time

Job summary

Parsons is hiring a hands-on Traffic Signal Operations Engineer to optimize signal timing and improve corridor progression in Riyadh, Saudi Arabia. The role focuses on live operations, timing adjustments, and data-driven intersection management within a central system environment.

You will review phasing, offsets, splits, and controller parameters, implement changes, and monitor results to ensure improved delay, queues, and throughput while avoiding secondary impacts at adjacent intersections.

Qualifications

• Bachelor's degree in Civil Engineering, Transportation Engineering, or Traffic Engineering.
• Minimum 3 years of hands-on experience in traffic signal timing, operations, or Traffic Control Center support.
• Strong written and verbal English communication skills.
• Experience with live signal timing changes in real environments.
• Familiarity with central signal systems and ATMS platforms.

Responsibilities

• Monitor signalized intersections and corridors using central signal systems and field observations.
• Review phasing, cycle lengths, offsets, splits, and controller parameters.
• Identify operational problems affecting capacity, progression, or reliability.
• Develop and implement approved timing adjustments for intersections and arterial corridors.
• Conduct before-and-after evaluations of timing changes and assess impact on delay and queues.
• Coordinate with maintenance teams on faults and system issues.
• Support adaptive signal control and priority treatments (e.g., transit, emergency).
• Maintain records of timing changes and performance measures for transparency.
