The Opportunity

The Principal Hydrogeologist – Portfolio Technical Lead will oversee the technical components of hydrogeology across our iron ore and lithium portfolio. Reporting to the Senior Manager – Water, this role will provide portfolio‑wide technical oversight, strategic planning, and modelling leadership across MinRes’s hydrogeological hubs – Onslow, Central Pilbara, and Lithium.

You will be responsible for ensuring consistent technical excellence, robust compliance strategies, and accurate water resource modelling to support long‑term water security and management.

While this role is primarily based at our Osborne Park headquarters, occasional site travel will be required to engage with stakeholders, participate in technical presentations, and support complex project discussions.

Key responsibilities:

• Lead portfolio‑wide hydrogeological strategy setting in collaboration with the Senior Manager – Water, ensuring alignment with operational, expansion, and exploration objectives.
• Provide high‑level technical support, guidance, and quality assurance to hub Principals and Senior Hydrogeologists across all hubs.
• Oversee and advise on complex hydrogeological modelling activities, including guidance on modelling approach, review, validation, and interpretation of results.
• Champion consistent technical standards and processes to ensure accurate water balance scenarios, aquifer characterisation, and dewatering impact evaluations.
• Offer strategic advice and technical interpretation on challenging hydrogeological issues for operational decision‑making, expansion approvals, and exploration feasibility studies.
• Support hub Principals in regulatory engagements by clarifying model outcomes and technical analysis when required.
• Lead and mentor the corporate hydrogeological modelling team to deliver accurate, defensible, and fit‑for‑purpose solutions across multiple geographies and commodities.
• Maintain deep understanding of Western Australian hydrogeology in the resources sector, including groundwater regimes across iron ore and lithium projects.
• Collaborate across disciplines to integrate hydrogeological strategy into project plans and operational management.
• Occasionally attend site stakeholder meetings when complex technical explanations are required, particularly relating to modelling results and strategic implications.

What is required?

• Tertiary qualifications in Hydrogeology, Geoscience, Environmental Science, or related technical field.
• Extensive professional hydrogeology experience, with substantial exposure to Western Australia’s resource sector.
• Proven ability to provide high‑level technical leadership across multiple operations in a multi‑commodity environment.
• Strong expertise in guiding and reviewing hydrogeological modelling (groundwater, aquifer behaviour, water balance) and validating technical outputs.
• Excellent capability to interpret complex modelling results and communicate findings to technical and non‑technical stakeholders.
• Demonstrated leadership and mentoring skills, fostering excellence and collaboration across multidisciplinary teams.
• Ability to work strategically at portfolio level while supporting operational priorities.
• Strong communication skills with the ability to convey technical concepts clearly in written reports, stakeholder meetings, and presentations.
• Current WA driver’s licence.
