• Operate and support the maintenance, calibration, and general upkeep of survey equipment, including underwater camera systems, benthic sampling equipment, positioning systems, and water quality profilers.
• Report equipment defects, non-conformities, and opportunities for continuous improvement.
• Ensure the safe collection, handling, storage, and return of environmental samples and survey data.
• Undertake seabed imagery review and analysis.

• Degree in Marine Biology, Marine Science, Oceanography, Environmental Science, or a related discipline.
• Valid offshore safety certification (e.g. STCW, BOSIET, or GWO).
• Valid offshore medical certification.
• Proficiency in Microsoft Office applications.
• Strong organisational and communication skills.
• Ability to work effectively within a team and in offshore environments.
