You will collaborate with Otak's multidisciplinary teams to support mitigation planning, design, and installation. Project work includes fish passage restoration, transportation, third-party peer reviews, linear utilities, parks and trails, and policy analysis. Project locations span rural and suburban or urban areas, road corridors, and agricultural lands throughout the Pacific Northwest.

This position includes a mix of field work and hybrid remote and in-office work, and is based out of our Redmond or Everett, Washington office. Travel to Southwest Washington and Oregon is expected on a project-by-project basis.
