Join a fast-growing geo-environmental consultancy delivering technically complex and nationally significant projects across the UK. At Tetra Tech, you’ll work alongside industry-leading specialists on high-profile developments in sectors including Defence, Water, Energy, Nuclear and Property, helping clients solve complex environmental and land quality challenges while developing your own technical and leadership expertise.

Purpose & Scope of the Role

As a Principal Geo-environmental Consultant based in Leeds, you will join a northern geo-environment team of 30 specialists and become part of Tetra Tech’s national team of over 100 geo-environment professionals across 10 UK and Ireland offices.

You’ll lead and support a broad range of geo-environmental projects for organisations including the MOD, Homes England, Harworth Estates, United Utilities, Yorkshire Water and major airport operators. Working within multidisciplinary teams, you’ll provide technical oversight across the full project lifecycle, from desk studies and site investigations through to remediation design, implementation and regulatory liaison. You’ll also contribute to a business that has grown significantly in recent years and continues to invest in innovation, people development and flexible working.

The role also involves reviewing health and safety documentation, supporting compliance with CDM regulations, overseeing remediation works and providing geo-environmental support across the wider northern team.

Collaboration & Client Engagement

You’ll work closely with clients, regulators and multidisciplinary teams, building trusted relationships and delivering practical, sustainable solutions. Strong communication and report-writing skills are essential, alongside confidence engaging with both technical and non-technical stakeholders.

Mentoring & Professional Development

You’ll mentor and support junior colleagues through technical guidance, training and project delivery oversight. We actively support Chartership through structured mentoring aligned with The Geological Society, including Chartered Geologist and Chartered Scientist pathways, alongside attractive Chartership bonuses.

Innovation & Digital Capability

You’ll embrace digital tools and modern working practices, including GIS, AI and specialist contamination software, to improve efficiency and enhance technical delivery across projects.

Skills, Qualifications & Experience

You’ll hold a degree or master’s in geology, engineering geology or environmental science, with substantial geo-environmental consultancy experience across contaminated land assessment and remediation projects. You’ll be self-motivated, commercially aware and confident managing workloads and deadlines within a collaborative team environment. Eligibility for UK Security Clearance (SC level) and a full UK driving licence are required.
