Transportation Civil Engineer IV

AECOM is seeking a Transportation Civil Engineer IV to join our Transportation team in Phoenix, Arizona. This is an exciting opportunity for an experienced transportation engineering professional to serve as a technical lead and subject matter expert on roadway and highway design projects throughout Arizona and the Southwest.

In this role, you will provide technical direction and engineering expertise across a variety of transportation infrastructure projects, supporting planning, preliminary engineering, final design, and project delivery. You will lead the development and review of roadway design plans, specifications, and technical calculations while coordinating with multidisciplinary teams to deliver high-quality, constructible, and cost-effective solutions. You will serve as a technical resource for project managers and other engineers, help establish design approaches, perform quality reviews, and support the development of innovative transportation solutions.

AECOM's Arizona transportation practice supports a diverse portfolio of infrastructure improvements, including highway and freeway widening, interchange improvements, roadway reconstruction, corridor improvements, intersection design, safety enhancements, and multimodal transportation projects. You will also contribute to business development efforts by supporting technical proposals, developing project approaches, participating in client presentations, and helping position AECOM for future transportation opportunities.

This position is ideal for an experienced engineer who enjoys solving complex design challenges, sharing technical knowledge, and playing an important role in delivering transportation infrastructure that improves mobility and connectivity throughout Arizona.
