Hydrographer

Hydrographer High‑resolution hydrographic and geophysical data supports navigation, protects infrastructure, and informs development across coastal and offshore environments. Ports, agencies, and marine operators rely on a clear understanding of submerged conditions to plan expansions, maintain assets, and manage risk. At David Evans and Associates, Inc. (DEA), we deliver hydrographic surveying, marine geophysics, and geospatial services that define seafloor conditions and support ports, infrastructure, and construction. Our team integrates advanced survey platforms, specialized instrumentation, and multidisciplinary expertise to produce decision‑ready results. With more than 25 years supporting NOAA and decades of experience with federal agencies, ports, and private clients, DEA brings proven capability to complex marine environments. Crewed and uncrewed platforms expand our coverage and efficiency, supporting reliable data delivery in dynamic conditions. What You’ll Do This position will be based in our Vancouver, WA office, but will require frequent travel to remote and/or offshore project locations to support hydrographic and/or geophysical fieldwork.

Coordinate and collaborate with the project team(s) to review project plans and provide project updates. Perform in‑field quality assurance, data management, and documentation activities. Conduct in‑field mobilization and demobilization of survey vessels and equipment. Work independently or as a team to analyze and process hydrographic data, prepare survey documentation, produce project deliverables, and perform quality control checks of work products and procedures.
