Principal Geotechnical Engineer – Underground Structures

We are seeking an experienced Principal Geotechnical Engineer with a proven track record in the design and delivery of underground tunnels and shafts in both soft ground and hard rock conditions. You will join a diverse team of engineers, scientists and modellers, contributing to landmark projects across the UK, Ireland and internationally.

• 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 multidisciplinary 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.
• Mentor junior engineers and contribute to internal training programmes and knowledge‑sharing initiatives.
• 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.

• 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, Geo Studio) and interpretation of ground investigation data.
• Demonstrated ability to manage complex projects and lead multidisciplinary teams.
• Excellent communication skills and willingness to travel within the UK and internationally.
