Senior Geotechnical Engineer

As a Senior Geotechnical Engineer, you will be working for CEL 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. CEL

• Costain’s in house multi-disciplinary engineering and design team delivers 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. By joining us, you will have the opportunity to work on some of the UK’s most high-profile infrastructure projects, such as 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. This hybrid role will be based in Manchester with office attendance typically 3 days a week along with a blended approach to remote working to promote wellbeing. #LI-MR1 Responsibilities 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. Knowledge, Skills, and Experience Essential UK experience as a Geotechnical Engineer or Engineering Geologist within civil engineering consultancy delivering design packages. Digitally proficient in undertaking design calculations using industry recognised packages, mainly Plaxis 2D/3D and Oasys Geotechnical Suite packages. Experience scoping & analysing field and laboratory data to develop ground models and derive project-specific geotechnical solutions. Proven working knowledge of UK regulatory frameworks (e.g. CDM Regulations). Good awareness of geotechnical data management and workflow automation. Excellent communication and relationship building skills to collaborate across multidisciplinary project team. Desirable Multi-sector project experience such as Rail, Water, Energy and Highways. Rock mechanics experience. Ability to utilise computational design tools and programming languages, such as Grasshopper or Python, for automation and data processing tasks. Environmental and sustainability considerations in project work. Essential Degree qualified in Civil Engineering, Geotechnical Engineering, Geology or Engineering Geology or equivalent experience. Chartered status (e.g. CEng or CGeol), or near chartered can be considered depending on experience.
