Lighting and Control System Engineer (Roads O&M)

Position Summary

The Lighting and Control Systems Engineer is responsible for the operation, maintenance and performance of all lighting and lighting control assets on the RF-001 expressway network. The role covers conventional road lighting together with decorative and architectural lighting, smart lighting control networks, and underpass and tunnel lighting. The engineer ensures that all systems meet the applicable standards, achieve the required performance levels, and comply with contract KPI and SLA obligations.

Key Responsibilities

Decorative and Architectural Lighting

• Plan and supervise operation and maintenance of decorative and architectural lighting on bridges, interchanges, landmark structures and feature installations.
• Manage DMX512 and RDM controlled fixtures, scene programming, colour change sequences and show schedules; verify addressing, universes and data integrity across controllers.
• Diagnose data line, driver and node faults; maintain controller backups, scene libraries and as built control documentation.

Smart Lighting and Control Networks (Planned Future Scope)

• Support the planning, trial and future rollout of smart lighting control based on LoRaWAN, including gateways, nodes, network servers and a central management system (CMS). This scope is not yet implemented on the contract.
• Configure DALI and DALI-2 drivers, dimming profiles, calendar and astronomical time scheduling, and fault and energy telemetry as systems are introduced.
• Support feeder pillar monitoring, remote switching and metering integration, including device commissioning, provisioning and firmware updates.
• Develop performance, energy and fault reporting from CMS data to support contract KPI and SLA reporting once the system is operational.

Underpass and Tunnel Lighting

• Operate and maintain underpass and tunnel lighting in line with CIE 88 and BS 5489, covering threshold, transition, interior and exit zones.
• Manage daytime and night time stage dimming, luminance controllers, photometric (L20) sensors and traffic linked control logic.
• Verify emergency and standby lighting, UPS supported circuits, and, where applicable, integration with tunnel SCADA, ventilation and incident management systems.
• Confirm luminance levels, uniformity and the absence of flicker through scheduled measurement and inspection.

General Operations, Quality and Safety

• Lead fault finding, planned preventive maintenance and corrective works across street, decorative and tunnel lighting assets on the 29 expressway network.
• Supervise subcontractor and in house teams, review work orders in the asset management system, and enforce quality and SLA compliance.
• Prepare technical reports, method statements, risk assessments and as built records; support trials, retrofits and the HPS to LED conversion programme.
• Apply electrical safety, permit to work and Ashghal HSE requirements at all times.
