Senior Hydrogeologist

ITASCA North America | Canada-based

About the role

ITASCA North America is seeking a Senior Hydrogeologist to support challenging mining, groundwater, and environmental projects across Canada and North America.

This role is suited for a technically strong professional with experience in groundwater hydrology, contaminant hydrogeology, field investigations, groundwater flow and contaminant transport modeling, and technical reporting. Mining experience is strongly valued, particularly in mine water management, dewatering, depressurization, seepage, closure, permitting support, and hydrogeologic support for mine planning and operations.

Why this role matters

Water is often a defining factor in how mining, infrastructure, energy, and environmental projects are planned, permitted, operated, and closed.

As a Senior Hydrogeologist, you will help clients understand groundwater systems, evaluate uncertainty, and turn field data, project constraints, and models into practical recommendations. Your work will support mine water management, groundwater characterization, dewatering strategy, contaminant transport assessment, permitting, closure planning, and risk management.

What you'll do

• Lead or support hydrogeology, mine water, groundwater, and environmental projects.
• Plan, supervise, and interpret field investigations, including drilling, monitoring well installation, groundwater and surface water sampling, aquifer testing, and hydraulic testing.
• Interpret monitoring and testing data and develop conceptual hydrogeologic models.
• Develop, apply, or review groundwater flow and contaminant transport models.
• Analyze hydrogeologic, geochemical, and environmental data.
• Prepare technical reports, presentations, proposals, scopes of work, budgets, and work plans.
• Manage technical tasks or projects, including schedules, budgets, deliverables, and quality.
• Communicate technical findings to clients, regulators, project teams, and other stakeholders.
• Supervise and mentor junior and intermediate staff.
• Contribute to client relationships, proposal development, and the growth of ITASCA North America's hydrogeology practice.

What you bring

Required

• Advanced degree in hydrogeology, geochemistry, environmental engineering, or a related field.
• Approximately 10–20 years of relevant professional experience.
• Proven technical excellence and sound professional judgment in hydrogeology or a related field.
• Professional registration by a recognized organization, or ability to obtain registration where required.
• Experience with hydrogeologic field investigations, groundwater monitoring, aquifer or hydraulic testing, and data interpretation.
• Experience developing or interpreting conceptual hydrogeologic models.
• Experience with groundwater flow and/or contaminant transport modeling.
• Strong technical writing, verbal communication, and presentation skills.
• Ability to work independently on complex assignments and manage scope, schedule, and budget.
• Experience supervising or mentoring technical staff.
• Ability to support proposals, work programs, and client development.

Strongly valued

• Mining industry experience, particularly in mine water management, pit dewatering, depressurization, seepage, closure, water balance, permitting, or operational hydrogeology.
• Experience with contaminant hydrogeology, aqueous geochemistry, groundwater/surface water interaction, water supply, or remediation.
• Experience with MODFLOW, FEFLOW, MINEDW, MT3D, or other transport modeling tools, GIS, or data analysis.
• Experience supporting environmental impact assessment, permitting, regulatory engagement, or closure planning.
• Experience working with multidisciplinary teams involving hydrogeology, geomechanics, engineering geology, geochemistry, data science, and numerical modeling.
