Scientific Programmer "Adaptation of the elliptical solver to coastal taks" (m/f/d)


The Coastal Ecology section at the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI) invites applications to adapt elliptic solver to coastal tasks. You are expected to have skills in high-level programming. The position is an excellent opportunity to get familiar with the coastal ocean models and their performance aspects.


  • Adaptation of the existing elliptic solver (iterative process) to solve problems on mixed unstructured grids (triangular and quads) in 2-D space;
  • Adaptation of the elliptical solver to open boundary areas and wetting/dry zones;
  • Solver control optimization;
  • Based on the existing 2D solver, creating a 3D solver with an implicit vertical procedure;
  • Porting of the FESOM-C model to DKRZ HPC Levante;
  • Analysis of multidimensional model outputs on HPC with Python, Xarray and Dask.


  • Master degree in Computer Science, Mathematics, Oceanography, Physics or related fields;
  • Strong background in high-level programming;
  • Good communication skills in English;
  • Strong motivation;
  • Desirable: background in fluid dynamics or experience with the performance of numerical ocean simulations.
