About the role

As an expert in the use of groundwater modelling tools we are looking to you, the Specialist Groundwater Modeller, to provide the technical leadership required to best inform water related risk at our 16 iron ore mines in the Pilbara. 

In your position as Specialist Groundwater Modeller in the Water Resource Evaluation (WRE) Group – Resource Development you will play a pivotal role in the transformation of conceptual hydrogeological models into mathematical decision making planning tools.


Working Monday to Friday, 40 hours and reporting to a regional Hub Superintendent you will be:

  • Responsible for the development, construction and maintenance (reconciliation) of mathematical flow models to support WRE in the assessment of environmental impacts, management of mine dewatering and water supply requirements for mines in your assigned Hub.
  • In partnership with the Hub hydrogeologists and the Technical Assurance Lead, managing the modelling pipeline including the coordination, planning and delivery of models.
  • Identifying opportunities for continuous improvement in the mathematical modelling space.
  • Promoting a high level of competency in conceptual and mathematical modelling that is aligned with business drivers.
  • Mentoring Project Modellers and enjoy working in a team environment. and,
  • Scheduling works loads, project management, including controlling costs, and ensuring quality performance.

About you

To be successfully considered for this role we value your technical capability, including:
