Key responsibilities

• Lead and support geophysical surveys using in-house equipment such as ERI, GPR, EM and HVSR
• Help design survey programmes to identify subsurface risks such as voids, utilities and varying bedrock depth, and integrate findings with geotechnical and geoenvironmental teams
• Support the design of third-party onshore surveys (MASW, 2D reflection and refraction, wireline and cross-hole seismic) and near-shore marine surveys (SBP, magnetometer, 2D reflection and refraction), with field supervision and offshore certification and training provided
• Process raw field data with industry-standard software (e.g. Res2DInv, Geolitix) and assist with the interpretation of 2D and 3D seismic datasets (IHS Kingdom)
• Carry out structural analysis and fault mapping, integrating geophysical, borehole and field data
• Write technical reports with clear visualisations and recommendations
• Manage field equipment maintenance and uphold health and safety standards on site

Required profile
