WSP USA is seeking a Senior Traffic Engineer to join our New England based team covering Massachusetts, Rhode Island, Connecticut, Maine, New Hampshire, and Vermont. This role provides high‑level technical assistance and guidance for the analysis, improvement, planning, engineering, design, and operation of streets, highways, and related transportation infrastructure. Responsibilities include performing traffic engineering analyses, designing roadways, intersections, complete streets, roadside safety, work zones, and traffic signal design and timing, while ensuring delivery of high quality outcomes that meet or exceed industry standards.

The selected candidate must be authorized to work in the United States.

• Apply high‑level traffic engineering techniques and processes to identify improvements for various project phases involving roadway transportation engineering work including concept development, preliminary design, final design, procurement, construction, and operation.
• Perform professional traffic engineering work and conduct investigations and inspections of proposed and existing site conditions, roadways, intersections, roadside safety measures, signage, signals, pavement markings, and transportation corridors to determine conformance with applicable rules, standards, and construction or operating permits.
• Develop and design innovative concepts for strategic intersection and corridor improvements, including near‑term initiatives and longer‑term capital improvement projects and studies that require coordination with authorities, sub‑consultants, and clients.
• Design communications networks and traffic signal improvements to facilitate remote, real‑time corridor operations.
• Develop and incorporate advanced technologies, monitoring devices, modeling techniques, design requirements, and operating strategies to account for the safety and functionality of end‑users, transportation vehicles/systems, and implement future‑ready solutions with traffic engineering design standards.
• Provide technical assistance on complex or larger‑scale traffic engineering studies, capacity analyses, traffic plan review, signal system design, monitoring and control, and operations analysis.
• Prepare data and visualizations such as tables, charts, reports, models, cross‑sections, and other illustrations for the interpretation or presentation of more complex data, findings, or analyses.
• Prepare comprehensive technical reports and presentations that explain research, concepts, and recommendations to prevent, control, restore, or address engineering, design, and/or construction issues or opportunities.
• Collaborate with professionals, other engineers, planners, and DOT authorities on Federal, State, regional, and locally funded road and transportation improvement and development projects, as well as proposal and business development opportunities.
• Remain current in latest traffic engineering techniques and practices.
• Exercise responsible and ethical decision‑making regarding company funds, resources and conduct, and adhere to WSP’s Code of Conduct and related policies and procedures.
• Perform additional responsibilities as required by business needs.

• Bachelor’s degree in civil engineering, or closely related discipline (or equivalent experience).
• 5 to 7 years of relevant post‑education experience in engineering and prior traffic design experience.
• Professional Engineer license required, preferably in one of the New England states.
• Proficient and extensive knowledge of traffic engineering principles, practices, processes, and design/build related to traffic engineering preliminary and final design, including functional layouts of roadways, traffic control signals and equipment, capacity and operational analysis, and related communications systems.
• Experience with roadway planning, design, and construction management, including experience in preliminary and final design of roadways, access/egress, intersections, pedestrian elements, and bicycle accommodations. Previous work should also include project involvement in a variety of larger and more complex infrastructure projects, rehabilitation and…
