Principal Geochemist

SLR is a global leader in sustainability solutions, helping clients tackle some of the world's most complex environmental and sustainability challenges. With over 5,000 employees operating across more than 125 countries, we combine global reach with local expertise, delivering innovative and practical solutions through a collaborative, people-first culture. As part of our continued growth, SLR's busy Mine Water team is seeking an experienced Principal Geochemist to join our expanding European Geochemistry team and support a growing portfolio of work, predominantly within the mining sector.

This role will provide technical leadership across a diverse range of mining projects, with a particular focus on mine waste and tailings geochemistry, acid rock drainage and metal leaching (ARD/ML), mine water quality, predictive geochemical modelling and mine closure. Acting as one of the team's senior technical practitioners, you will lead complex studies, provide technical oversight and mentor developing geochemists while collaborating closely with multidisciplinary specialists across hydrogeology, hydrology, water treatment, mining, tailings, waste management, environmental assessment and closure disciplines.

This is an excellent opportunity for an established geochemist to shape technical approaches, influence project outcomes, strengthen client relationships and contribute to the continued growth, technical development and reputation of SLR's geochemistry practice. The role can be based from any of SLR's UK offices, with flexible, agile and hybrid working options available. Occasional international travel will form part of the role.

As a Principal Geochemist, you will provide technical leadership across a broad range of mining projects throughout the mine lifecycle while supporting the development of both clients and colleagues.

• Leading the technical delivery of complex geochemistry studies across the mining lifecycle, including Scoping Studies, Pre-Feasibility Studies (PFS), Feasibility Studies (FS), Environmental and Social Impact Assessments (ESIA), operational support and mine closure planning.
• Providing senior technical direction for mine waste and tailings geochemical characterisation programmes, including sample selection and the design of static, kinetic, leach and mineralogical testing programmes.
• Leading the interpretation of complex geochemical datasets and undertaking robust assessments of ARD/ML, salinity, constituent mobilisation and long-term water quality risks.
• Developing practical geochemical management and mitigation strategies for waste rock, tailings, stockpiles, pit walls and other mine materials.
• Developing and reviewing geochemical source terms and water quality predictions to support mine water management, groundwater studies, water balances, closure planning and permitting requirements.
• Undertaking and overseeing advanced geochemical modelling using PHREEQC.
• Providing specialist technical input to mine closure studies, including pit lakes, flooded mine workings, seepage quality assessments, mine water treatment requirements and post-closure monitoring programmes.
• Integrating geochemistry with mine waste, tailings, hydrogeology, hydrology, mine water and closure engineering studies to deliver practical, risk-based recommendations.
• Acting as a technical reviewer and quality assurance lead for geochemistry deliverables.
• Leading technical investigations, field programmes, sampling campaigns and laboratory testing strategies where required.
• Managing project scopes, programmes, budgets, resources, laboratories and subcontractors.
• Supporting proposal development, project planning, client engagement and business development initiatives.
• Building and maintaining strong client…
