• Seismic reflection systems (single-channel and multi-channel preferred)
• Marine vibracore systems and other geotechnical samplers
• Acquire, process, and interpret integrated geophysical and geotechnical datasets
• Prepare maps, figures, and technical reports for engineering, regulatory, and scientific applications
• Support data processing and interpretation workflows using industry-standard software
• Mentor junior staff and assist with training and development in both field and office settings
• Support survey planning, logistics, and proposal development as needed

• Bachelor of Science degree (or higher) in geology, geophysics, oceanography, or a related field
• 4+ years of relevant marine geoscience experience
• Experience supporting marine geophysical surveys using:
• Chirp sub-bottom profiler
• Sidescan sonar
• Magnetometer
• Experience with marine geotechnical sampling, including vibracores or similar systems
• Experience with geophysical acquisition and interpretation software (e.g., Sonar Wiz, Hypack, Discover or equivalent)
• Strong technical writing and organizational skills
• Ability and willingness to support extended offshore rotations (typically 10-14 days) in physically demanding environments

• Prior experience acting as a Field Party Chief or senior field lead on offshore surveys
• Experience with multi-channel seismic acquisition and interpretation
• Experience with survey planning and vessel mobilization
• Familiarity with GIS and mapping software (e.g., ArcGIS, AutoCAD, Surfer)
• Experience supporting projects involving permitting, routing, or geohazard assessments

• This position is heavily field-based, with a significant portion of time spent offshore
• Candidates must be adaptable, safety-focused, and capable of working in dynamic marine environments
