Senior Water Resources Engineer

AKS is seeking an experienced Senior Water Resources Engineer with a Certified Floodplain Manager (CFM) certification to join our growing team in Tualatin. This individual will bring a strong technical background in floodplain analysis, hydraulic modeling, and flood risk assessment, and will collaborate with multidisciplinary teams, provide technical leadership on flood-related projects, coordinate with regulatory agencies, and help clients navigate complex floodplain regulations and permitting requirements.

What You’ll Do

• Develop, manage, and perform advanced 1D and 2D hydraulic and floodplain modeling for rivers, streams, drainage systems, and watersheds.
• Prepare and evaluate hydrologic and hydraulic analyses to support floodplain mapping, flood hazard assessments, and infrastructure design.
• Develop, calibrate, validate, and interpret hydraulic models using industry-standard modeling software.
• Perform FEMA-related floodplain studies, including Flood Insurance Studies (FIS), Flood Insurance Rate Map (FIRM) revisions, Conditional Letters of Map Revision (CLOMR), and Letters of Map Revision (LOMR).
• Prepare technical reports, engineering calculations, floodplain studies, and supporting documentation for regulatory and client submittals.
• Evaluate flood risks and develop practical mitigation strategies for public infrastructure, private development, and community improvement projects.
• Provide technical guidance on FEMA regulations, National Flood Insurance Program (NFIP) requirements, local floodplain ordinances, and applicable state and federal permitting requirements.
• Support floodplain development permitting, including floodway encroachment analyses, no-rise certifications, and substantial improvement/substantial damage evaluations, as applicable.
• Coordinate with FEMA, state and local agencies, floodplain administrators, and other regulatory stakeholders.
• Collaborate with civil engineers, surveyors, natural resource specialists, planners, and other technical professionals to integrate floodplain considerations into multidisciplinary projects.

Who You Are

• Bachelor's degree in Civil Engineering, Water Resources Engineering, Environmental Engineering, or a related discipline.
• Minimum of 7 years of professional experience in floodplain modeling, hydraulic analysis, and water resources engineering.
• Active Certified Floodplain Manager (CFM) certification.
• Professional Engineer (PE) license in Oregon or Washington, or the ability to obtain licensure through reciprocity, preferred.
• Demonstrated experience with both 1D and 2D hydraulic modeling and floodplain analysis.
• Strong understanding of FEMA floodplain mapping standards, NFIP regulations, floodway analyses, and floodplain development requirements.
• Experience preparing and reviewing FEMA-related technical documentation, including CLOMRs, LOMRs, and floodplain mapping studies.
• Strong technical writing, analytical, problem-solving, and communication skills.
• Ability to manage multiple projects, coordinate with clients and regulatory agencies, and deliver quality technical work within established schedules and budgets.
• Ability to work independently while contributing to a collaborative, multidisciplinary team.

Nice to Have

Experience with several of the following tools and technical applications is highly desirable:

• HEC-RAS (1D and 2D hydraulic modeling).
• HEC-HMS hydrologic modeling.
• FLO-2D or comparable 2D hydraulic modeling platforms.
• GIS applications, including ArcGIS Pro, for floodplain mapping and spatial analysis.
• FEMA floodplain mapping and regulatory processes.
• Hydraulic structure analysis, including bridges, culverts, and roadway crossings.
• Floodway encroachment and no-rise analyses.
