•  Lead geotechnical design for underground structures including tunnels, shafts, and associated works from concept through detailed design and construction phases.

•  Apply advanced soil and rock mechanics principles to develop safe, efficient, and innovative solutions for underground projects.

•  Ensure compliance with relevant design standards and guidance (e.g., Eurocode 7, BS codes, ITA guidelines, and applicable local regulations).

•  Undertake and review geotechnical analyses such as stability assessments, ground-structure interaction modelling, and support system design.

•  Oversee ground investigation planning, interpretation of geotechnical data, and development of geotechnical baseline reports.

•  Manage technical delivery of multi-disciplinary projects, coordinating inputs from structural, civil, and environmental teams.

•  Provide expert advice on excavation methods, ground improvement techniques, and temporary/permanent support systems.

•  Conduct site inspections, supervise construction activities, and provide technical input during tunnelling and shaft sinking operations.

•  Support business development through proposal preparation, client engagement, and participation in industry conferences.

• Promote health, safety, and equality in all aspects of work, adhering to company policies and values.

What we will be looking for you to demonstrate

•  Degree qualified in Civil Engineering, Geotechnical Engineering, or Engineering Geology (postgraduate qualification desirable).

•  Extensive experience in geotechnical design for underground tunnels and shafts in soft ground and/or hard rock.

•  Strong understanding of ground behaviour, soil and rock mechanics, and geotechnical risk management.

•  Familiarity with tunnelling methods (e.g., TBM, NATM, SCL) and shaft sinking techniques.

•  Proficiency in geotechnical analysis software (e.g., PLAXIS, FLAC, GeoStudio) and interpretation of ground investigation data.

•  Demonstrated ability to manage complex projects and lead multi-disciplinary teams.

•  Excellent communication skills and willingness to travel within the UK and internationally.
