Geo- Environmental Consultant

Join Tetra Tech as a Geo-environmental Consultant

As a Geo-environmental Consultant, you will be involved in the delivery of technically complex projects helping clients solve ground engineering and land quality challenges while developing your technical skills.

Join a growing Geo-Environmental Team of around 100 specialists across 10 offices in the UK and Ireland, delivering consultancy and in‑house ground investigation services across Energy, Water, Defence, Nuclear and Property. This role focuses on contaminated land, site investigation and brownfield redevelopment, supporting projects across sectors including property and regeneration, defence estates and transport. It is an excellent opportunity to build your expertise within a collaborative, inclusive and fast‑growing technical environment.

You will help shape and deliver geo‑environmental investigations from desk study through to interpretation and reporting. Working across site and office locations, you will support the design, procurement, supervision and management of ground investigations, undertake desktop assessments, collect and interpret site data, produce clear technical reports, and carry out groundwater and ground gas monitoring and assessment. Your contribution will directly support sustainable development, risk management and environmental improvement on a wide range of complex sites.

• Technical Knowledge

  Strong geo‑environmental knowledge, experience in contaminated land investigation and assessment, and current standards and guidance. Experience in environmental due diligence would also be an advantage.

• Site Investigation & Supervision

  Confidence in managing and supervising ground investigation works on site, including groundwater and ground gas monitoring, with a strong focus on quality and delivery.

• Data Analysis & Reporting

  Comfortable collecting, analysing and interpreting site data, and producing Phase 1 geo‑environmental desk studies, preliminary risk assessments and Phase 2 interpretative reports.

• Communication & Collaboration

  Clear verbal and written communication, strong presentation skills, and the ability to work effectively with colleagues, clients and contractors.

• Initiative & Professionalism

  Self‑motivated, proactive and able to work independently while maintaining high standards in health, safety and environmental management.

2–5 years’ experience in a similar role and a degree in geology, engineering geology, environmental science or a related subject. A full manual driving licence is required. Site accreditations such as SMSTS, SSSTS, CSCS or First Aid would be beneficial.

60% site based and 40% office based, depending on workload. Site work is typically around London and the South East, with occasional travel further afield in the UK and internationally. We support flexible working, including hybrid options, job shares and part‑time arrangements, and offer excellent opportunities for career development, including Chartership bonuses.
