The Max Planck Institute for Meteorology (MPI-M) is an internationally renowned center for climate research located in Hamburg, Germany. The MPI-M provides a vibrant international and interdisciplinary environment for conducting scientific research as well as access to state-of-the-art scientific facilities. The institute is located in the heart of one of Europe’s most livable cities, and embedded in an environment known worldwide for its breadth of climate research.
The EU Horizon 2020 Project ESM2025 (GA 101003536) aims to develop the next generation of Earth System Models (ESMs) by integration of new components in the ESMs, the representation of interactions and couplings between the components within the ESMs, and the improvement of key climate processes through the use of machine learning/artificial intelligence or the use of constraints derived from available observations. The Research Group Ocean Biogeochemistry in the Department OES (The Ocean in the Earth System) is one of the major partners in ESM2025, we are looking for a

Postdoctoral Scientist (W098 | all genders)

fixed-term position for 36 months

The successful candidate will be part of a team developing the new Earth system model ICON-ESM. The focus of the work is on improving biogeochemical processes determining the ocean carbon sink within the model HAMOCC, the ocean biogeochemistry component of ICON-ESM. This includes, but not limited to the representation of the marine nitrogen cycle, nutrients co-limitation, sinking of particulate organic carbon and shell material, remineralization, and air-sea exchange, as well as effects of vertical ocean mixing and transport processes.  

Your tasks

  • Contribute to the development of HAMOCC within the new-coupled MPI-M Earth System Model (ICON-ESM) and designing numerical experiments with a focus on improving bio-geochemical processes and the carbon cycle.
  • Supporting scientific cooperation within ESM2025 project partners.
  • Disseminating the results through peer-reviewed publications and presentations at con-ferences.

Our Requirements:  

  • A PhD in Geosciences, Oceanography, Environmental Sciences, or a related field.  
  • Experience in performing and analyzing experiments with a comprehensive Earth system model or ocean biogeochemical model.
  • Experience with high-performance computing environments and complex scientific codes is required.
  • Motivation and ability to participate in model development in an interdisciplinary and in-ternational environment.
  • Excellent communication skills and publication record.

What we offer

  • The position is offered for 36 months, starting as soon as possible.  
  • Payment will be in accordance with German public service positions (TVoeD E14), includ-ing extensive social security plans. The conditions of employment, including upgrades and duration, follow the rules of the Max Planck Society for the Advancement of Sciences and those of the German civil service.  
  • The Max Planck Society strives for gender and diversity equality. We welcome applica-tions from all backgrounds.  
  • Handicapped persons with comparable qualifications receive preferential status.

Candidates will be evaluated based on their qualifications and ability to fulfill the responsibil-ities as outlined for this project.
