The Position

We’re growing our geotechnical team in Cardiff and are looking for a practical, flexible Principal & Senior Geotechnical Engineer to play a key role in our continued expansion. This is an opportunity to join a busy, supportive office delivering a diverse range of projects across domestic and commercial structures, rail, bridges and temporary works, spanning both public and private sectors. You’ll take ownership of selected projects, work closely with engineers and technicians, and be supported by senior leadership, with real scope to develop your career while contributing directly to the wider growth of the business.

We are ideally looking for an experienced Principal Engineer, but we also encourage applications from experienced Engineers who are ready to progress to Principal level, with structured support and mentorship provided.

Responsibilities

• Take technical and delivery ownership of geotechnical projects, leading and approving designs for temporary and permanent works, with a strong focus on reviewing and checking the work of others.
• Lead project delivery across your remit, managing priorities, outputs, programmes and quality standards.
• Oversee and coordinate engineers and technicians within the team, providing technical direction and guidance.
• Manage project delivery activities including programmes, resourcing, forecasting and invoicing input.
• Prepare and review technical reports, feasibility and option studies, and associated project documentation.
• Undertake site inspections and geotechnical surveys where required.
• Act as a key client contact and support relationship development and business development activity.
• Collaborate with other offices and disciplines, mentor junior staff, and contribute to team and wider business growth.

Preferred Profile

• Degree qualified (BSc, BEng or MEng) in Geotechnical Engineering, Civil Engineering, Engineering Geology or a closely related discipline.
• Extensive relevant experience in geotechnical engineering alongside demonstrable experience leading technical scopes, project packages or small teams.
• Chartered status (or near-chartered) with a recognised professional body (e.g. CEng or CGeol).
• Experience working on UK projects and familiarity with UK standards and practice.
• Strong technical reporting skills and a high standard of written and spoken English.
• Independent right to live and work in the UK.
• Rail sector experience, geotechnical inspections/surveys, and familiarity with engineering software (e.g. GEO-5, FEM tools, CAD) beneficial but not essential.
• Full UK driving licence useful but not essential.
