Senior Groundwater Modelling Specialist
Location: Remote with occasional travel to Saudi Arabia
Job Type: Contract
About the Role
We are seeking an experienced Senior Groundwater Modelling Specialist to support a major groundwater and environmental programme in Saudi Arabia. This role is primarily remote, with occasional travel required for client meetings, workshops, site visits, and project activities.
The successful candidate will lead the development and application of advanced groundwater models to support sustainable groundwater management, environmental assessments, and urban infrastructure planning. Working within a multidisciplinary team, you will provide technical leadership throughout the modelling lifecycle, from conceptual model development through to predictive simulations and client training.
Key Responsibilities
- Collect, review, analyse, and interpret hydrological, hydrogeological, geological, and environmental datasets to support groundwater modelling studies.
- Develop conceptual hydrogeological models and build robust numerical groundwater models using industry-standard software such as MODFLOW, FEFLOW, or equivalent.
- Define model boundaries, hydrostratigraphy, hydraulic properties, boundary conditions, and initial conditions.
- Calibrate and validate groundwater models using observed field data and undertake sensitivity and uncertainty analyses.
- Perform predictive groundwater simulations to evaluate management strategies, environmental impacts, and future development scenarios.
- Develop interactive dashboards and visualisation tools to communicate modelling results and project performance.
- Prepare high-quality technical reports, modelling documentation, presentations, and project deliverables.
- Deliver technical training and knowledge transfer sessions to client personnel on groundwater modelling methodologies, software, and interpretation of results.
- Work collaboratively with multidisciplinary teams including hydrogeologists, hydrologists, environmental specialists, GIS professionals, and engineers.
- Ensure all work is completed in accordance with project quality standards, HSE requirements, and client expectations.
Required Qualifications
- MSc or PhD in Hydrogeology, Hydrology, Water Resources Engineering, or a related discipline.
- Minimum 15 years of experience in groundwater modelling and hydrogeological investigations.
- Demonstrated expertise in conceptual and numerical groundwater modelling.
- Advanced experience using MODFLOW, FEFLOW, or comparable groundwater modelling software.
- Strong understanding of groundwater flow processes, aquifer characterisation, hydraulic parameter estimation, model calibration, validation, and sensitivity analysis.
- Experience supporting urban groundwater, infrastructure, or environmental water resource projects.
- Experience developing dashboards and data visualisation tools (e.g. Power BI, ArcGIS Dashboards, Python, or similar).
- Strong technical report writing and presentation skills.
- Experience delivering client training and knowledge transfer programmes.
- Excellent communication skills in English.
Preferred Experience
- Previous experience supporting groundwater resource management projects in arid or semi-arid environments.
- Experience working with government agencies, utilities, or major infrastructure projects.
- Familiarity with GIS software and groundwater data management.
- Previous experience working on projects in the Middle East is advantageous.
What We Offer
- Remote working with occasional travel to Saudi Arabia.
- Opportunity to contribute to a high-profile groundwater management programme.
- Collaborative, multidisciplinary project environment.
- Long-term contract opportunity with exposure to technically challenging and innovative groundwater modelling projects.
