Hydrological Modelling and GIS Analyst

This role is part of Aon’s Impact Forecasting Flood team, which develops catastrophe flood models used in the re/insurance industry. The analyst will work on large-scale hydrological modelling and GIS processing to help turn precipitation data into flood footprints and loss estimates for clients. Responsibilities include collaborating with the Flood team on rainfall-runoff modelling and flood mapping, calibrating and testing large-scale rainfall-runoff models using gauge and historical precipitation data, developing and refining stochastic flood event sets, leading GIS and data workflows that link flood footprints, event definitions and exposure data to quantify losses, maintaining and enhancing event response infrastructure using external data such as satellite flood footprints and internal flood zones, contributing to post-event and predictive workflows for recent and forecast floods, and automating and stabilizing processing pipelines using Python and GIS tools. Candidates should have a university degree in Hydrology, Cartography, Meteorology, Climatology, Geography, Mathematics, or a related Earth science field. They should have strong skills in either GIS and raster data processing or hydrology/environmental modelling, with interest in growing in the other area. Experience using Python or R to automate tasks, ideally for GIS, raster, or environmental data, is required. A careful and structured approach to data quality checks and documentation is expected. Additional pluses include experience with hydrological rainfall-runoff or other environmental models, satellite or remote-sensing data such as flood footprints, Linux, Git, cloud or remote servers, catastrophe modelling, flood risk assessment, or a related field. Applicants must have a valid work permit in Czechia.
