Data Modelling and Preparation Engineer (M/F)

Job Description

Missions

The engineer will be responsible for modelling our proxy system (PSM) and preparing a comprehensive set of harmonised, documented and ready-to-use palaeoclimate data for the model and data evaluation exercises within the ARCHIVES project

Activity

Collect, verify, and harmonize paleoclimate proxy datasets (stable isotopes, tree rings, marine and lacustrine sediments, speleothems, etc.).
Develop statistical tools, scripts and workflows enabling:
· the conversion of proxy signals into interpretable climate variables,
· the quantification, propagation and documentation of uncertainties.
· structuring the data in standard formats (NetCDF, interoperable formats) compatible with Earth System models and climate analysis tools.
Document the methodologies, manage versions (Git), and write user guides for the databases produced.
Contribute to the technical deliverables of the ARCHIVES project and to the preparation of the datasets required for numerical experiments.

Your Profil

Skills

Required Skills:
· Master's degree (or equivalent) in climate science, geosciences, environmental data processing, applied statistics/machine learning, or a related field.
· Proficiency in programming (Python, R) and the Linux/Unix environment.
· Experience in handling large environmental datasets (NetCDF, xarray, pandas).
· Proficiency in statistical analysis/AI approaches and time series processing.
· Experience in database management, metadata structuring and documentation.
· Ability to work independently and as part of a collaborative team.
· Good level of scientific English.
Desired Skills:
· Knowledge in paleoclimatology and the interpretation of the main types of proxies.
· Familiarity with proxy-system modeling concepts.
· Experience in projects involving model-data comparison or data assimilation.
· Knowledge of data management and dissemination standards (FAIR data, DOI, data catalogs).

Your Work Environment

The successful candidate will join a highly dynamic scientific team working on the ARCHIVES project and, more generally, within the PEPR-TRACCS program. The ARCHIVES project aims at improving the use of paleoclimate reconstructions to better constrain Earth System models parameters.
Within this framework, proxy-system modeling is a key methodological tool for establishing a rigorous link between simulated climate variables (temperature, precipitation, circulation, water isotopes, etc.) and signals measured in natural archives.
The recruited Engineer will play a central role in preparing harmonized, documented, and directly usable paleoclimate datasets for the project's model-data evaluation exercises, based on databases already available in the literature. The position is part of a collaborative environment involving climate modelers, paleoclimate archive specialists, and data processing experts. Constraints and Risks concern mainly the handling of heterogeneous and sometimes incomplete databases. The activities need to ensure complete traceability and reproducibility of procedures involving large volumes of data and shared computing environments.
The position is based at LOCEAN on the Pierre and Marie Curie campus of Sorbonne University. The LOCEAN laboratory (https://locean-ipsl.upmc.fr) is one of nine laboratories in the Paris region specializing in environmental and climate sciences at the Institut Pierre-Simon Laplace (IPSL) (https://www.ipsl.fr). The LOCEAN team's work focuses on studying the physical processes that control ocean and climate dynamics and variability over a wide range of time and space scales to better understand the climate system and its present, past, and future evolution. The close synergy between the scientific teams at LOCEAN and other IPSL laboratories within the IPSL Climate Modeling Center (https://cmc.ipsl.fr) enables research and development of a climate model based on the integration of several components for the atmosphere, the ocean, sea ice, and continental surfaces. It regularly participates in international exercises such as the Climate Model Intercomparison Project, on which the work of the Intergovernmental Panel on Climate Change is based. Modeling activities rely on both GENCI's large national computing centers and a dedicated IT infrastructure located at the IPSL premises.
