About the role

Key responsibilities & impact

Develop, calibrate, apply, and review numerical groundwater flow models for mining, environmental, and water-resource projects
Support modeling related to mine dewatering, depressurization, pit and underground working inflows, groundwater recovery, contaminant transport, seepage, closure, and water management
Develop and interpret conceptual hydrogeologic models using geology, field data, monitoring records, hydraulic testing, groundwater chemistry, and project constraints
Evaluate model assumptions, calibration, uncertainty, sensitivity, limitations, and implications for client decisions
Prepare technical reports, model documentation, presentations, proposals, scopes of work, budgets, and work plans
Serve as a technical reviewer and internal resource for groundwater modeling quality
Mentor junior and intermediate staff in modeling methods, hydrogeologic interpretation, and technical communication
Work independently on complex assignments and manage modeling tasks or projects
Collaborate with hydrogeologists, geomechanics engineers, engineering geologists, geochemists, data scientists, and software developers
Support continued improvement of ITASCA’s modeling skills, workflows, training materials, and technical capabilities
As appropriate, work with the MINEDW product manager and in-house software staff to support groundwater model code development, feature improvements, user training materials, and marketing content

Requirements

What you’ll need

Advanced degree in hydrogeology, geochemistry, environmental engineering, or a related field
Approximately 10–20 years of relevant professional experience
Proven record of technical excellence in groundwater flow modeling
Strong experience developing, calibrating, applying, and interpreting numerical groundwater models
