Experienced Hydrogeologist/Modeler (M/F)
CONTRACT
Permanent Contract for Project
Working hours
Full time
Contract duration
Undetermined
Context
The Water Directorate (DE) is tasked with addressing societal needs related to water resource management and the environmental impacts of human activities on these resources in the context of climate change. You will join the Numerical Aquifer Modeling (MNA) Unit to contribute to modeling activities and the development and/or validation of the performance of various hydrogeological and hydrological calculation codes. This will involve bringing innovative approaches to support research and knowledge about aquifer systems and associated water environments (rivers, wetlands, etc.), aiming to optimize their quantitative and qualitative management at different scales (local, regional, national) and support the adaptation of hydrosystems to the transitions linked to global changes.
Mission description
Your main responsibilities will include:
– Contributing to projects supporting public or international policies on the quantitative and qualitative management and protection of groundwater resources, particularly in relation to surface water, seawater, and global changes;
– Modeling groundwater flow in relation to surface water (groundwater-river exchange and urban network) and modeling the transport of associated solutes/heat/mass (saltwater intrusion/point source and diffuse pollution/impacts of climate change, etc.);
– Contributing to the integration of innovative approaches to hydrogeological modeling using artificial intelligence and/or data assimilation and multi-objective optimization methods for management under uncertainty;
– Disseminating results through technical reports and publications;
– Presenting scientific results and communicating them effectively to all types of stakeholders, and being able to engage in dialogue with multidisciplinary teams.
Profile
Holding a Master’s degree, engineering degree, or PhD in hydrogeology, you ideally have initial postdoctoral or industry experience; international experience would be an asset.
You will also bring the following skills and qualities:
• Scientific and technical expertise
; • Solid knowledge of hydrogeology and expertise in flow modeling and transfer and transport processes;
• Proficiency in meshed calculation codes (MODFLOW-6, Marthe) and scripting approaches in Python, ideally with FloPy;
• Experience in algorithmic calibration and uncertainty analysis, particularly with the PEST/PEST++/PyEMU suite;
• Knowledge of saltwater intrusion contexts and variable density flow modeling;
• Rigor, organizational skills, and adherence to contractual obligations;
• Initiative and scientific creativity;
• Interpersonal skills and a passion for working in a multidisciplinary team.
• Excellent written and oral communication skills for publishing, presenting at conferences, and leading training sessions;
• Fluent written and spoken English.
Desired start date: As soon as possible.
Contract type: Permanent project-based contract.
Desired experience: 5-10 years.
