TotalEnergies' core value is the safety of its collaborators. Some of our facilities are located on riverbanks, with transport occurring mainly by waterway. Weather conditions can cause the water level in these rivers to change rapidly and significantly, presenting a risk of flooding or navigability challenges. Predicting these water levels is highly dependent on weather forecasts, resulting in complex time series that require the use of modern artificial intelligence methods, including uncertainty quantification.

As a Junior Data Science R&D Mathematical Engineer (M/F), your main mission will be to develop modern deep learning models for complex time series forecasting.

• The first objective is to work on long-term weather predictions using generative AI modeling methods from scientific literature (such as flow matching, for example).

• The second aspect involves using these predictions and their uncertainty to infer a height with an AI model for dynamic systems (such as State Space Models, for example).

This work will lead to a publication and may continue as a PhD thesis.

TotalEnergies is above all looking for skills and personalities and welcomes all talents representing the diversity and richness of profiles. For many years, we have pursued a proactive policy promoting professional inclusion and supporting employees with disabilities throughout their careers.
