Transportation Engineer Jobs in Washington: Frequently Asked Questions
How do you become a transportation engineer in Washington?
Becoming a transportation engineer in Washington starts with a bachelor's degree in civil or transportation engineering from an accredited program, followed by passing the Fundamentals of Engineering exam to become an Engineer in Training. After gaining qualifying work experience under a licensed engineer, you apply to the Washington State Department of Licensing for your Professional Engineer license, which is required for signing off on public infrastructure projects and is the standard credential Washington public agencies and private consulting firms expect.
How much do transportation engineers make in Washington?
Transportation engineers in Washington earn a median of about $110,000 a year, based on May 2025 Bureau of Labor Statistics wage data, ranging from around $81,840 for the lowest 10% to over $160,670 for the top 10%. Pay rises with experience, specialty, and employer.
Which companies hire transportation engineers in Washington?
Washington transportation engineer roles are posted by Ardurra, WSP, and Otak and others right now, based on current listings on Migrate Mate as of November 2026. Washington's mix of large public agencies, regional transit authorities, and national engineering consultancies with Seattle-area offices creates a broad and consistent hiring pool.
Which Washington cities have the most transportation engineer jobs?
Seattle, Everett, and Wenatchee account for the most transportation engineer openings in Washington. Seattle and Bellevue anchor the market because of ongoing Sound Transit light rail expansion and dense private consulting activity, while Olympia draws demand from WSDOT headquarters and state agency contracting, and other regional centers benefit from proximity to major highway corridor and ferry system projects.
Are there remote transportation engineer jobs in Washington?
Yes, but they're rare. About 100% of transportation engineer openings tied to Washington are remote or hybrid as of November 2026, reflecting how site-dependent much of the work is. Roles centered on traffic data analysis, transportation planning studies, or report writing are the most likely to offer partial remote flexibility, while field inspection and construction oversight positions almost always require on-site presence.
How can I get hired as a transportation engineer in Washington with little or no experience?
The most realistic entry path is applying for Engineer in Training or junior engineer roles at WSDOT or large King County consulting firms, which regularly bring on new graduates through structured cohort hiring. Local transportation planning firms also hire analysts and design technicians who work toward PE licensure on the job. Passing the FE exam before applying and building a portfolio with AutoCAD or Civil 3D project samples gives candidates a clear edge over those without the credential or software exposure.
Where can I find and apply to transportation engineer jobs in Washington?
You can find and apply to transportation engineer jobs in Washington on Migrate Mate, which lists current Washington openings updated in real time. Search the available roles, identify the ones that match your experience and location, and apply directly to the ones that fit.
