ST3 Planning Coordinator; Capital Projects Coordinator, Sr

At the Seattle Department of Transportation (SDOT), we don’t just move people—we connect communities, build safer streets, and create a more sustainable city.

With a bold vision for the future, we’re tackling big challenges: making travel safer, cutting carbon emissions, and ensuring reliable, affordable transportation for everyone—no matter who they are or where they live.

Seattle is growing fast, and we’re growing with it. Thanks to a historic voter-approved $1.55 billion investment in transportation in 2024, we’re building sidewalks, fixing bridges, and improving transit connections to keep our city moving.

We’re a team of problem solvers, planners, engineers, communicators, and field crews—bringing purpose-driven work to life. Now, we need passionate, innovative talent like you. Let’s build a Seattle that works for everyone—together!

In November of 2016, central Puget Sound region voters approved Sound Transit's ST3 program-currently one of the largest transit expansion programs in the United States. Within Seattle, ST3 includes the West Seattle Link Extension (WSLE) and Ballard Link Extension (BLE) projects that will design and construct 12 new or expanded stations and nearly 12 miles of light rail connecting neighborhoods of West Seattle, South Lake Union, and Ballard to downtown Seattle and the regional transit system, as well as key infill stations along existing light rail lines such as the South Graham Street infill station.

While Sound Transit is the regional agency responsible to fund, design, and deliver these capital investments, the Office of the Waterfront, Civic Projects and Sound Transit, a program office within SDOT, carries out essential City functions to plan and permit ST3 projects built within the city, particularly within City owned right-of-way and properties. The City's program will also implement station access improvements and encourage transit-oriented development around new stations.
