Graduate Hydrographic Surveyor

Support marine survey projects by assisting with hydrographic and geophysical data acquisition, processing, and reporting for offshore and coastal infrastructure projects.

About the Position

As a Graduate Hydrographic Surveyor, you will work with the project leadership team to support the acquisition, processing and interpretation of geophysical and hydrographic data across a range of marine survey projects. It is a hands-on graduate role designed to give you real breadth: mobilisations, field acquisition on our vessels, and office-based data processing and reporting.

This role will involve working both on-site and in the office / from home, as required. You must be based in the North West or Wirral, or willing to relocate before starting.

Duties & Responsibilities

Under the direction of senior management, you will be responsible for:

• Supporting the installation, calibration and operation of multibeam echosounder, sidescan sonar, sub-bottom profiler, magnetometer and positioning systems on a range of nearshore and offshore projects

• Assisting with the acquisition, quality control and processing of geophysical and bathymetric datasets, using QPS QINSy and other industry-standard software

• Supporting survey planning, mobilisations and equipment setup

• Contributing to survey reports for clients across offshore renewables, ports and harbours, nuclear new build and coastal infrastructure

• Maintaining health, safety and quality standards on every task

• Supporting other duties as directed by senior management that are deemed reasonably practicable

About You

We are looking for an enthusiastic recent graduate who can demonstrate the following:

• A proactive attitude and a genuine willingness to learn new techniques and new software. This is the most important thing for us. Attitude matters more than a perfect skills match on day one.

• Based in the North West or Wirral, or willing to relocate before starting (essential)

• Degree-qualified in a relevant scientific subject (e.g., Hydrographic Surveying, Geophysics, Geography, Marine Geography, Geomatics, Marine Science, Ocean Engineering, Physics or Geology)

• A basic understanding of the principles behind multibeam, sidescan, sub-bottom and magnetometer systems, or a strong interest in learning them if your course only touched on surveying techniques

• Prior placement, internship or dissertation project in a hydrographic, geophysical or wider marine environment (preferred)

• Familiarity with QINSy, Qimera, SonarWiz, FMGT, PDS or Oasis Montaj (preferred)

• Full UK driving license (essential)

• Strong attention to detail and problem-solving skills

• Proficient with MS Office applications

• Willingness to work flexibly and spend periods offshore around tidal cycles

• Ability to work effectively as part of a team, both on-site and in an office environment

• Right to work in the UK
