Job summary

Moody's is seeking a GIS-flood modeller to join a specialized Model Development team focused on high-resolution hydrologic and hydraulic models for flood hazard assessment. You will work on elevation models, geospatial input layers, and advanced AI/ML methods to improve model development and workflow automation.

As part of a multidisciplinary group, you will calibrate models against observed data, validate outputs, and communicate insights to stakeholders.

Qualifications

• Strong background in GIS, hydrology, or climate science with quantitative methods.
• Experience applying ML to geospatial or environmental data.
• Familiarity with large-scale data pipelines and HPC workflows.
• Ability to communicate complex concepts across disciplines.

Responsibilities

• Join a collaborative scientific team building high-resolution, large-scale hydrologic and hydraulic models and contribute to model components, data pipelines, validation, and research.
• Contribute to the development and application of large-scale flood hazard model components, including elevation models and other geospatial input layers, stochastic rainfall, rainfall‑runoff processes, hydraulic routing, floodplain inundation, and flood‑defence failure mechanisms.
• Calibrate and validate model components with a focus on GIS, using observed data, published research, and benchmark datasets, including comparisons between simulated and observed flood extents and depths.
• Evaluate model outputs such as flood footprints, hazard metrics, and loss patterns using statistical methods, visualisation, and GIS tools.
• Advance flood model input layer preparation, including elevation models, land use data, and remotely sensed data, through research, evaluation, and implementation of novel scientific and computational techniques.
• Explore, prototype, and evaluate AI and ML methods for model‑development challenges including surrogate modelling, spatial downscaling, feature extraction, anomaly detection, data processing, emulator development, and workflow automation.
• Contribute to the development of reproducible scientific workflows, code repositories, and data‑processing pipelines using modern software development practices.
• Communicate research findings and modelling insights to internal stakeholders, clients, and the broader scientific community.
• Contribute to an inclusive, collaborative culture through knowledge sharing, constructive review, and continuous learning.

About the Team

Our Model Development team brings together scientists, engineers, and data specialists to build natural catastrophe models for hazards including tropical and extra‑tropical storms, winter storms and convective storms, coastal and inland flooding, and tsunamis. The Inland Flood team develops high‑resolution, large‑scale hydrologic and hydraulic models spanning hazard through loss, combining observations, reanalysis and climate data, numerical and statistical modelling, engineering methods, and data assimilation. As AI and machine learning evolve, we integrate them selectively alongside established physical and statistical approaches to improve model development, data processing, quality assurance, and scientific insight. By joining the team, you will contribute to meaningful scientific work, grow as a GIS specialist or flood modeller, and help advance Moody's position as a global leader in catastrophe risk assessment.
