About WSDOT

The Washington State Department of Transportation (WSDOT) is a multimodal agency with a global reputation for excellence. Our dedicated workforce plans, designs, builds, and operates an integrated transportation system that safely and efficiently moves people and goods throughout the state. In addition to maintaining over 20,000 lane miles of state highway and 4,100 bridges, WSDOT manages the world’s longest floating bridge, leads an award‑winning Active Transportation Plan, holds the record for the world’s widest tunneling project, and operates the largest ferry system in the nation!

WSDOT is seeking a motivated, mission‑driven Transportation Engineer 3 to join our State Hydraulics Office as a Stormwater and Drainage Design Lead. This is an opportunity to take on meaningful engineering challenges that protect people, restore ecosystems, and keep Washington’s transportation system moving safely and sustainably. In this dynamic role, you’ll be at the forefront of designing stormwater, hydraulic, and hydrologic solutions for some of the most complex transportation projects in the state.

You’ll collaborate directly with Project Engineering Offices across Washington, mentor project staff, and help ensure our designs meet the highest standards of environmental stewardship and regulatory compliance. Your work will support WSDOT’s core values of safety, innovation, leadership, and sustainability, all while helping shape the infrastructure that millions of travelers rely on every day. If you are ready to make a real impact on Washington’s transportation future, we encourage you to apply!

Among the varied range of responsibilities held within this role, the Stormwater and Drainage Lead will:

• Lead stormwater and hydraulic design efforts for transportation projects statewide, using tools such as MGSFlood, Storm
  
  Shed3G, and other advanced modelling software.
• Conduct field investigations, drive to project sites to assess drainage conditions, examine existing conveyance systems and existing stormwater Best Management Practices (BMPs), identify potential sites for new stormwater BMP and new conveyance systems, and examine the project site to help identify constraints to the stormwater and hydraulic design.
• Analyze drainage basins and determine stormwater flows, seasonal construction flows, treatment BMP needs, and stormwater conveyance design requirements.
• Mentor and coach project staff across the state on stormwater and hydraulics design procedures.
• Apply statewide standards, including the Hydraulics Manual and Highway Runoff Manual.
• Identify and resolve stormwater and hydraulic design issues before final design.
• Work closely with multidisciplinary teams, including engineering offices, environmental teams, and specialty groups to ensure projects are delivered successfully.
• Carry out various related duties that keep our hydraulics program running smoothly and effectively.

To be considered for this opportunity, the following are required:

• Hydraulics, Hydrology, and Stormwater Engineering Design: Foundational knowledge of engineering with focus on producing and delivering stormwater and hydraulic designs obtained through extensive experience, Engineering‑in‑Training certification or formal education.
• Technical Tools & Workflows: Experience using hydraulic and hydrologic modelling tools and managing technical workflows. Skilled in managing digital workflows for storing, retrieving, and producing stormwater, hydrologic, and hydraulic data for use in technical reports and design documentation.
• Analysis & Reporting: Experience conducting analysis of drainage basins using various techniques to calculate stormwater flows such as MGSFlood, Storm
  
  Shed3G, and/or other hydraulic and hydrologic software to determine flow rates and volumes of stormwater.
• Leadership & Communication: Proven ability to mentor, train, and lead technical design staff in workflows, design principles, stormwater, hydrology, and hydraulics topics. Demonstrated experience communicating complex information to both technical and non‑technical audiences.
• Growth Mindset: Actively demonstrates a commitment to…
