Posted on Monday, February 5, 2024

GEOMAR Helmholtz Centre for Ocean Research Kiel is a foundation under public law jointly financed by the Federal Republic of Germany (90%) and the State of Schleswig-Holstein (10%). It is one of the internationally leading institutions in the field of marine research.

Through our research and our commitment to the transfer of knowledge and technology, we contribute significantly to the preservation of the function and protection of the ocean for future generations. The research group OSTIA “The ocean’s role in mitigating climate change” is funded by the European Research Council. Its objective is to improve our understanding of the legacy of ocean storage of anthropogenic carbon and heat for future climate, and of the importance of the ocean’s “weather” (ocean mesoscale phenomena) therein.

The research unit Biogeochemical Modelling of the research division 2 is offering a

Scientific Programmer position (m/f/d)

in Earth System Modelling (OSTIA-SciProg)

starting on June 1st 2024.

Job Description

  • Main tasks will be the development of a novel Earth system model set-up with a mesoscale-rich ocean, optimization of model run time, carrying out of centennial-scale climate change simulations that reach beyond phasing out of fossil fuel emissions, post-processing of model results, including the development of a workflow to reduce storage needs (e.g., data compression), data transfers and archiving, and visualization of model results and benchmarking against observations.
  • The scientific programmer position will be embedded into a larger ocean and Earth system modelling team, and with scientific project partners who are concerned with the response of the ocean to climate change. The position will be located within the Biogeochemical Modelling research unit at GEOMAR, a group with diverse research themes in marine biogeochemistry and climate, including the anthropogenic perturbation of the global carbon cycle. High performance computing facilities and infrastructure support is provided via the National High Performance Computing Alliance and Kiel University.



  • Master or PhD in Computational Fluid Dynamics, Climate Sciences, or a related field
  • Experiences in Earth system modelling or computational fluid dynamics modelling, including considerations of optimizing model run time
  • Experiences with high performance computing facilities
  • Experiences with handling of large data files that require consideration of, e.g., memory or storage limits
  • Skills in analyses and visualization of model results, such as with Matlab or Python
  • Communication skills in German and English

It is beneficial to have:

  • previous experiences with the climate model FOCI - Flexible Ocean and Climate Infrastructure or the ocean model NEMO - Nucleus for European Modelling of the Ocean
  • knowledge of Fortran

At a workplace, directly on the Kiel Fjord with many leisure and recreational opportunities, we offer you:

  • Good conditions for work-life balance: We offer, among other things, the possibility of mobile working and individual working time arrangements, vacation courses for the children of our employees, and good support in finding a place in a daycare center at the Kiel site
  • Support services for professional and personal life situations
  • An exciting work environment with the opportunity to provide important impetus for the development of sustainable solutions
  • Exciting topics in an international environment
  • Work in the field of marine and climate research, a forward-looking area with social significance
  • 30 vacation days + additional time off at Christmas and New Year's Eve
  • Company pension plan and capital-forming benefits

The position is available for a funding period of four years (end of project: May 31st, 2028). The salary depends on qualification and could be up to the class E13 TVöD-Bund of the German tariff for public employees. This is a full-time position. Part-time employment is generally possible with the framework of suitable working time models.
