• Assist with modeling related to mine dewatering, depressurization, inflows from pits and underground workings, groundwater recovery, contaminant transport, seepage, closure, and water management.

• Create and analyze conceptual hydrogeologic models utilizing geology, field data, monitoring records, hydraulic testing, groundwater chemistry, and project constraints.

• Assess model assumptions, calibration, uncertainties, sensitivities, limitations, and their implications for client decisions.

• Produce technical reports, model documentation, presentations, proposals, scopes of work, budgets, and work plans.

• Act as a technical reviewer and an internal resource for groundwater modeling quality assurance.

• Guide junior and intermediate staff on modeling techniques, hydrogeologic interpretation, and technical communication.

• Operate independently on intricate assignments and oversee modeling tasks or projects.

• Collaborate with hydrogeologists, geomechanics engineers, engineering geologists, geochemists, data scientists, and software developers.

• Contribute to enhancing ITASCA’s modeling skills, workflows, training materials, and technical capabilities.

• Work alongside the MINEDW product manager and in-house software team as necessary on groundwater model code development, feature enhancements, user training materials, and marketing content.

⛳️ Requirements

• Advanced degree in hydrogeology, geochemistry, environmental engineering, or a related discipline.

• Approximately 10–20 years of pertinent professional experience.

• Demonstrated record of technical excellence in groundwater flow modeling.

• Significant experience in developing, calibrating, applying, and interpreting numerical groundwater models.

• Familiarity with conceptual hydrogeologic models, hydrogeologic data interpretation, and model documentation.

• Capacity to critically assess model assumptions, calibration, uncertainties, sensitivities, and limitations.

• Experience in working independently on complex technical projects.

• Ability to supervise, manage, mentor, and review the work of others.

• Experience in the mining industry, especially in areas like mine dewatering, depressurization, pit inflow, pore-pressure estimation, water balance, closure, groundwater recovery, or operational hydrogeology.

• Knowledge of finite-element and/or finite-difference groundwater modeling techniques.

• Experience with contaminant transport modeling, parameter estimation, uncertainty analysis, sensitivity analysis, or stochastic modeling.

• Programming or scripting experience with Python, R, VBA, or similar tools.

• Familiarity with GIS, 3-D visualization, large datasets, database tools, or model pre/post-processing workflows.

• Experience in designing field investigations, aquifer testing, hydraulic testing, groundwater monitoring, or data collection programs.

• Expertise in developing modeling workflows, training materials, software documentation, or user-facing technical content.

• Professional registration from a recognized organization, or the ability to obtain such registration when necessary.
