Geotechnical Site Engineer

LSTC Group Ltd is a powerhouse in delivering full turnkey solutions that shape the future of the electricity sector. As part of the SOCOTEC Group, we are a leading infrastructure testing and asset inspection specialist serving the UK's regulated energy sector.

From initial design to inspection of assets, our work makes a real difference to clients and communities, with sustainability at the core of everything we do. With contracts across multiple sectors in the UK's power transmission and distribution infrastructure, we use our expertise to solve diverse engineering challenges, enhancing reliability and efficiency across the network.

Our extensive in-house capabilities eliminate the need for multiple suppliers and simplify processes for our clients. We provide comprehensive services including:

• Overhead Line Design
• Geotechnical & Foundation Engineering
• Underground Cable Design
• Substation Design
• Asset Inspection
• Infrastructure Projects
• Surveying and Earthing Services

We support transmission owners, distribution network operators, independent connection providers, and project developers who collectively invest billions annually in maintaining and expanding the UK's energy infrastructure.

At LSTC Group Ltd, we're looking for a driven and results-oriented Geotechnical Site Engineer to join our growing project team. If you're passionate about ground investigation, enjoy variety in your workday — from desk study to site supervision to report writing — and want to build your career towards chartership, this role is for you.

What you'll be doing

• Taking projects on a journey: from desk study and site reconnaissance, through ground model development, to site investigation and final geotechnical reporting.
• Supervising and managing subcontractors on site across the UK, ensuring work is delivered safely, on time and within budget — including occasional out-of-hours and weekend work.
• Logging and sampling soils to British Standards, and preparing/reviewing factual and interpretive ground investigation reports.
• Supporting foundation design in line with UK and client standards.
• Liaising directly with clients — understanding their briefs, agreeing deliverables, and keeping them updated on progress and quality.
• Preparing budgets, schedules, fees and programmes, and submitting monthly progress reports.
• Reviewing method statements and risk assessments, and championing health & safety and CDM compliance on every project.
• Mentoring and supporting less experienced engineers, sharing your knowledge and helping shape the next generation of geotechnical talent.
• Traveling across the UK to project sites and, where needed, working from our Tadcaster and other LSTC offices.

What we're looking for

• A Bachelor's or Master's degree in Civil Engineering, Geology, Geotechnical Engineering or a related field.
• At least 2 years' experience in ground investigation.
• Ideally, membership (or progress towards chartership) with ICE or GSL.
• A valid UK driving licence.
• Solid understanding of British Standards and Eurocode Design principles.
• Strong IT skills (MS Office essential; working knowledge of GIS tools like ArcGIS/QGIS a plus; CAD or geotechnical/structural software experience is a bonus).
• Excellent communication and report-writing skills, high attention to detail, and strong numeracy.
• A proactive, flexible, self-motivated approach — someone who thrives on variety and enjoys collaborating across disciplines.

Why join LSTC Group?

This is your opportunity to work on a diverse portfolio of projects spanning conceptual design through to construction, gain hands-on site experience across the UK. Please note that this is a field based role but the Geotechnical team are based in Tadcaster and you will be expected to attend this office on a regular basis among some of our other offices across the UK.
