About the Role:

We are currently seeking an experienced Senior Geotechnical Design Engineer on behalf of our client to become a pivotal part of their expanding practice. In this position, you will drive the development and delivery of geotechnical solutions for diverse and complex infrastructure initiatives. Working alongside multidisciplinary engineering professionals, you will craft technically sound, pragmatic designs spanning initial feasibility and concept phases all the way through to detailed design and execution. This position offers the opportunity to take technical ownership of specialized geotechnical packages while partnering closely with broader civil and structural engineering teams.

About You:

The ideal candidate thrives on unraveling complicated engineering problems and designing highly effective, real-world solutions. You are a natural collaborator who excels in cross-disciplinary environments, easily forging strong partnerships with both peers and external stakeholders. You demonstrate sound engineering judgment, a proactive mindset, and a deep commitment to the successful delivery of every project.

Core Responsibilities:

• Produce high-quality geotechnical calculations, specifications, designs, and comprehensive technical documentation.
• Evaluate and design earthworks, slopes, retaining walls, deep and shallow foundations, and other associated ground elements.
• Analyze ground investigation findings to extract reliable geotechnical parameters and formulate targeted design advice.
• Execute advanced geotechnical assessments using industry-standard analytical and numerical modeling tools.
• Assess ground improvement strategies and earthworks schemes, focusing on stability, settlement, bearing capacity, and overall constructability.
• Ensure all design work strictly complies with relevant UK and European regulatory frameworks, including Eurocode 7.
• Draft, review, and finalize technical reports, engineering drawings, and project specifications.
• Supply specialized geotechnical expertise at every project phase, from early conceptualization to final detailing.
• Partner closely with structural, civil, and other engineering disciplines to ensure seamless design integration.
• Pinpoint potential geotechnical hazards and devise safe, constructible, and cost-effective mitigations.
• Offer on-site technical guidance and construction support when necessary.
• Audit the technical output of peers and actively mentor junior engineering staff.
• Assist in broader project delivery duties, ensuring quality control, schedule adherence, and inter-discipline coordination.
• Foster enduring professional relationships with key stakeholders, contractors, and external partners.
• Participate in business development efforts, including the preparation of project bids and proposals.

Required Qualifications & Experience :

• Bachelor’s or Master’s degree in Civil Engineering, Geotechnical Engineering, or a closely related discipline.
• Chartered Engineer (CEng) designation via the Institution of Civil Engineers (ICE), or currently in the advanced stages of achieving chartership.
• Proven background within a design consultancy setting, consistently delivering geotechnical expertise for infrastructure or heavy engineering builds.
• Deep understanding of core soil mechanics, rock mechanics, and applied geotechnical engineering principles.
• Demonstrable track record designing retaining structures, foundations, slopes, and bulk earthworks.
• Proficiency in evaluating site investigation data to derive robust design parameters.
• Hands-on experience with prominent geotechnical design and analysis software packages.
• Exceptional written and verbal communication abilities, specifically in drafting complex technical reports.
• Capability to autonomously manage a technical workload while integrating smoothly into wider multidisciplinary teams.
• Confidence and clarity when presenting technical concepts to external partners and project stakeholders.
• A team-oriented mindset with a genuine enthusiasm for mentoring and supporting less experienced engineers.
