Senior Geotechnical Engineer
Due to continued growth within CEL, Costain’s in-house multi-disciplinary engineering and design team, we have an exciting new opportunity for a Senior Geotechnical Engineer to join our Ground Engineering team and work on some of the UK’s most high-profile infrastructure projects, including HS2 High Voltage Rail Systems, Net Zero Teesside Power and the Northern Endurance Partnership, AMP8 Water frameworks, and the HALEU (High Assay Low Enriched Uranium) project for Urenco.
CEL deliver comprehensive design solutions across a range of UK Infrastructure sectors - Energy, Defence & Nuclear, Water, Rail, Roads and Integrated Transport. We support the full project lifecycle from feasibility to construction, focusing on sustainable, future-ready, and safe-by-design outputs.
As a Senior Geotechnical Engineer, you will be working within the Ground Engineering team to deliver ground engineering solutions for our large pipeline of projects. You will own ground engineering activities and designs from outline design through to construction, producing high-quality reports, specification, and calculations. You will identify deliverables, manage ground risks, and solve live construction problems.
This is a hybrid role. Your office will be in Manchester, with office attendance typically up to 3 days per week, with remote working to promote well-being and occasional visits to other offices and sites.

No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
- Produce and check geotechnical calculations and specifications for shallow and deep foundations, retaining walls, and earthworks, while reviewing and guiding the production of BIM/CAD models and drawings.
- Process AGS files, manage geotechnical data, produce digital 2D/3D ground models, and derive soil/rock design parameters for engineering use. Contribute to team initiatives for automating repetitive tasks and calculations. Utilising programming languages such as Python would be advantageous.
- Produce industry-standard and Eurocode 7 compliant reporting such as desktop studies, Ground Investigation Reports (GIRs), and Geotechnical Design Reports (GDRs); plan and scope ground investigations, and scope/interpret laboratory and in-situ test results.
- Collaborate closely with internal engineers, specifically civils & structural, mechanical, and electrical engineers, as well as project managers to coordinate project activities, attend and input into design reviews and interdisciplinary design check sessions/meeting (IDCs), and deliver technical presentations.
- Independently manage your own workload to deliver assigned work packages to agreed cost, time, and quality standards, while managing change and resource allocations.
- Respond to site Technical Queries (TQs) for permanent and temporary works designs; guide construction teams by reviewing previous designs and proposing alternative ground and civil engineering solutions.
