Job description

The Climate Dynamics section of the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI) in Bremerhaven, Germany, is looking for a motivated and skilled Scientific Programmer. This role focuses on adapting the OpenIFS 48r1 atmospheric general circulation model (GCM) to integrate CMIP7 forcing files such as greenhouse gases (GHG), solar radiation, aerosols, ozone, etc. The development aspect of the task will be joined work coordinated with the EC-Earth community. The successful candidate will be involved in conducting tuning simulations to ensure that the coupled atmosphere-ocean model, AWI-CM3 MR, maintains an accurate climate state for CMIP7. Additionally, the role includes executing CMIP7 DECK simulations, standardizing model outputs, and uploading them to the ESGF node.

In this role, you will:

  • Modify the OpenIFS 48r1 GCM to read and integrate various CMIP7 forcing files.
  • Conduct tuning simulations to ensure the AWI-CM3 MR model is accurately represented for CMIP7 purposes.
  • Perform the CMIP7 DECK simulations using the AWI-CM3 MR.
  • Standardize the resulting model outputs and ensure their proper upload to the ESGF node.
  • Collaborate with top European climate modelers, computing scientists, and software engineers.


  • A master’s degree in software engineering, data science, computer science, mathematics, physics, meteorology, oceanography, climate sciences, or related fields. A PhD is preferred.
  • Demonstrated proficiency in Fortran, C++ or another statically typed, compiled programming language.
  • Demonstrated proficiency in Python, R, or another scripting language widely used for data analysis and processing.
  • Fluency in English.
  • Experience with version control systems like git, and familiarity with software testing and documentation practices.
  • Familiarity with high-performance computing (HPC) systems, parallel data processing, and data formats such as netCDF, GRIB, and Zarr is highly advantageous.

Further Information
For any questions you may have, you are very welcome to get in touch with Prof Dr Thomas Jung (
+49(471)4831-1761) or Dr Jan Streffing (; +49(471)4831-2479).

This is a full-time position, limited to 28months. It is also suitable for part-time employment. The salary will be paid in accordance with the Collective Agreement for the Public Service of the Federation (Tarifvertrag des öffentlichen Dienstes, TVöD Bund), up to salary level 13.
