HYDROGRAPHIC SURVEYOR (IMMEDIATE FILL)

Location: Imperial Beach, CA
Department: Marine Operations / Geospatial Services
Employment Type: Full-time

Position Overview

We are seeking a skilled Marine Hydrographic Surveyor to conduct precise underwater mapping and geospatial data collection in marine environments with vessel-mounted and unmanned hydrographic survey systems. This role combines advanced technical expertise in hydrographic surveying with hands-on marine operations, requiring both analytical precision and practical seamanship skills.

Key Responsibilities

Hydrographic Operations

  • Conduct multibeam and interferometric bathymetry surveys using industry-standard equipment

  • Perform side-scan sonar operations with autonomous underwater vehicles

  • Collect and process water column data including sound velocity profiles

  • Execute precise positioning using GNSS, RTK, and geodetic control networks

  • Validate survey data against established geodetic datums and coordinate systems

Data Management & Analysis

  • Process hydrographic data using industry-standard software (HYPACK, CARIS HIPS & SIPS, SonarWIZ, QPS Qimera, or similar)

  • Apply geodetic corrections and coordinate transformations

  • Generate bathymetric models, and technical survey reports

  • Ensure data meets IHO standards and client specifications

  • Maintain comprehensive survey documentation and metadata

Marine Operations

  • Operate small craft and have experience in working from mid-size research vessels and vessels of opportunity

  • Conduct SCUBA (air) diving operations for underwater inspection and environmental monitoring/mitigation tasks

  • Deploy and retrieve oceanographic instruments and survey equipment

  • Perform vessel maintenance and pre-survey equipment checks

  • Coordinate with vessel crews and diving safety officers

Required Qualifications

Education & Certification

  • Bachelor's degree in Hydrography, Ocean Engineering, Geodesy, Surveying, or related field

  • Geodetic Surveyor certification a plus

Technical Skills

  • Minimum 3 years experience in hydrographic surveying and geodetic applications

  • Proficiency with geodetic concepts including datums, projections, and coordinate systems

  • Experience with WGS84, NAD83, local geodetic networks, and datum transformations

  • Knowledge of tidal modeling, water level corrections, and uncertainty analysis

  • Familiarity with IHO S-44 standards and nautical charting procedures

Marine Operations

  • Commercial diving certification (PADI Advanced Open Water or equivalent)

  • Small boat operator's license or equivalent maritime certification

  • Experience operating vessels 20-35 feet in bay and coastal environments

  • Knowledge of marine safety protocols, emergency procedures, and maritime regulations

  • Physical ability to work in marine environments and handle heavy equipment

Software Proficiency

  • SonarWIZ, HYPACK, CARIS HIPS & SIPS, QPS Qimera, or equivalent hydrographic processing software

  • GIS software (ArcGIS, QGIS) and geodetic computation tools

  • Statistical analysis and uncertainty modeling applications

Physical/Adminstative Requirements

  • Ability to work outdoors in various weather conditions and marine environments

  • Capable of lifting equipment up to 50 pounds and working on unstable platforms

  • Swimming ability and comfort working in and around water

  • Willingness to travel and work extended periods at sea

  • Ability to travel to remote survey locations

  • Valid passport and driver's license

  • Ability to obtain and maintain appropriate security clearances if working on government contracts.

Application Requirements

Please submit:

  • Detailed resume highlighting hydrographic and geodetic experience

  • Cover letter describing relevant diving and marine operations experience

  • Portfolio of recent survey projects (if available)

  • Three professional references from hydrographic or marine operations background
