Lead drainage and stormwater design for transportation projects, including highways, roadways, intersections, transit corridors, and multimodal improvements.

Design storm drain systems, culverts, detention, conveyance systems, and other drainage infrastructure.

Perform hydrologic and hydraulic analyses, including watershed assessments, runoff calculations, pipe sizing, and drainage system modeling.

Prepare and oversee drainage reports, engineering calculations, plans, specifications, cost estimates, and construction documents.

Collaborate with roadway, structural, environmental, and other engineering disciplines to integrate drainage solutions into transportation projects.

Apply department of transportation and local agency drainage design standards and requirements.

Provide technical guidance, design reviews, and quality assurance and quality control (QA/QC) for drainage-related deliverables.

Build and maintain relationships with transportation clients and agency partners, contributing to proposals, project pursuits, and new business opportunities.

What You Bring to the Team:

Bachelor's degree in civil engineering or a related engineering discipline.

10+ years of progressive civil engineering experience, with significant experience in drainage design for roadway and transportation projects.

Professional Engineer (PE) license, preferably in Oregon or Idaho, or the ability to obtain licensure through reciprocity.

Strong technical background in hydrology, hydraulics, storm drain systems, culvert design, stormwater conveyance, and drainage infrastructure.

Experience preparing drainage reports, calculations, engineering plans, and construction documents for transportation projects.

Familiarity with ODOT, ITD, or comparable state and local transportation agency design standards.

Proficiency with hydrologic and hydraulic modeling and drainage design tools, such as HEC-RAS, HEC-HMS, HY-8, StormCAD, Civil 3D, or similar applications, as applicable to your project experience.
