Traffic Signal Technician

Position Summary

The Traffic Signal Technician (IMSA Certified) is responsible for the installation, programming, maintenance, troubleshooting, repair, and optimization of traffic signal systems, Intelligent Transportation Systems (ITS), pedestrian signals, vehicle detection systems, communication networks, and related traffic control infrastructure. This position combines field operations with technical and administrative responsibilities, supporting both transportation operations and signal system performance initiatives. The role may also assist with signal timing reviews, asset management, system documentation, project coordination, and contractor oversight.

Working independently and as part of a multidisciplinary transportation team, the Traffic Signal Technician applies advanced knowledge of traffic signal technologies, industry standards, electrical systems, communication networks, and safety practices to ensure the safe and efficient movement of vehicles, pedestrians, transit, and emergency responders. IMSA certification is required to verify competency in traffic signal operations, maintenance, troubleshooting, and field technologies.

This position aligns with market benchmarks commonly found within transportation agencies, municipalities, engineering consulting firms, and infrastructure service providers and is generally comparable to Radford/Aon Professional Level P3-P4 technical specialist roles and Mercer/Willis Towers Watson technical infrastructure positions.
