STM Environmental Consultants is growing, and we’re looking for an experienced Senior Geotechnical / Environmental Consultant to join our team.
Based in Twickenham, we are a well-established geo-environmental consultancy delivering high-quality environmental and geotechnical solutions to a wide range of clients.
While STM operates independently with its own strong reputation and client base, we are also part of a wider group of geo-environmental companies. This means you benefit from the best of both worlds — the close-knit, supportive environment of a specialist consultancy, alongside the backing, collaboration opportunities, shared expertise, and increased project exposure that come from being part of a larger group.
At STM, you’ll take real ownership of projects from day one, working within a collaborative team that genuinely values professional growth and technical excellence.
The Role
You will lead and manage geo-environmental site investigations while playing a key role in client liaison, regulatory engagement, and business development.
This is an ideal opportunity for someone ready to step into (or further develop in) a senior position with project leadership and people management responsibility.
Key Responsibilities
* Project managing geo-environmental site investigations, flood risk assessments, and ecology projects
* Producing and reviewing factual and interpretative reports
* Peer reviewing technical reports
* Liaising with Local Authority regulators
* Preparing quotations and supporting business development
* Managing and mentoring junior staff
* Liaising with and working along side other colleagues in the wider Phenna Infrastructure division
Skills & Experience Required
* Extensive experience in:
* Geotechnical ground investigations
* Contaminated land risk assessments
* Excellent technical report writing skills
* Strong IT proficiency
* Experience managing projects and people
* Strong communication and client-facing skills
* Minimum 5 years’ relevant experience
Qualifications
* Degree (BSc or MSc) in Geo-Environmental Science, Engineering, or related discipline
* Full UK driving licence (essential)
