Computational Scientist / scientific programmer position in Data Assimilation and Earth System Modelling at the Laboratoire des Sciences du Climat et de l’Environment (LSCE).

Description of responsibilities

Researchers at LSCE are developing an innovative global Carbon Cycle Data Assimilation System (CCDAS). The aim of this assimilation tool is to constrain the parameters of the land-surface model ORCHIDEE and thereby quantify and reduce the uncertainty of modelled carbon, energy and water fluxes. The candidate will join the team responsible for the development of the CCDAS and will contribute to its consolidation and improvement. Responsibilities will include the improvement of existing tools for local and global scale assimilation experiments, adaptation of the CCDAS for the use of more diverse data sources, research into the implementation of alternative optimisation algorithms, running simulations and post-processing and analysis of the assimilation results. The position is initially available for 1 year with the possibility of renewal for up to 2 years depending on satisfactory job performance.


The candidate should have an undergraduate, and preferably master’s, degree(s) in Computational Science, Mathematics or a similar quantitative physical science, and a broad interest in natural sciences – more specifically in biogeochemistry and land-atmosphere interactions. Priority will be given to those candidates with a background in data assimilation/inversion and/or work experience in a research environment. In addition, the candidate should have expert knowledge of computing tools such as Python, FORTRAN and/or IDL programming and the UNIX system. The candidate should be highly motivated with a proven ability to be innovative, dynamic and work collaboratively with a team of scientists.
