Job description:Scientific Programmer (m/f/d) in Climate-Vegetation Modeling

The Climate Dynamics section of the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI) in Bremerhaven, Germany, is now inviting applications for a Scientific Programmer. This position focuses on coupling the LPJ-Guess vegetation model with the OpenIFS general circulation model (GCM). The successful candidate will coordinate closely with Lund University and work on tuning and simulations with the AWI-ESM3 LR model.

  • Integrating the LPJ-Guess vegetation model with the OpenIFS GCM.
  • Coordinating model development and implementation strategies with Lund University.
  • Conducting tuning simulations to ensure the AWI-ESM3 LR model reflects accurate climatic and vegetative states.
  • Executing climate simulations and ensuring the accurate representation of coupled climate- vegetation interactions.
  • Collaborating with leading climate modelers and researchers from AWI and partner institutions.

  • A Master's degree in fields such as software engineering, data science, computer science, environmental science, ecology, meteorology, or related areas. A PhD is advantageous.
  • 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 and strong communication skills.
  • Practical experience with version control systems like git, and familiarity with software testing and documentation practices.
  • Previous experience in running or developing on the LPJ-Guess model is highly preferred.
  • Familiarity with high-performance computing (HPC) systems, parallel data processing, and data formats such as netCDF, GRIB, and Zarr is highly advantageous.

This research center is part of the Helmholtz Association of German Research Centers. With more than 42,000 employees and an annual budget of over € 5 billion, the Helmholtz Association is Germany's largest scientific organisation.


The Helmholtz Association contributes to solving major challenges to assure the future of our society. With more than 39,000 people on staff in 18 national research centres, the Helmholtz Association is Germany’s largest scientific organization. The name Helmholtz stands for concerted research in which networks form the key principle behind inquiring thought and action. Concerted research is efficient and flexible.

The profile of the Helmholtz Association

The Helmholtz Association performs cutting-edge research which contributes substantially to solving the grand challenges of science, society and industry. To succeed in meeting these responsibilities, Helmholtz concentrates its work in six research fields: Energy, Earth and Environment, Health, Key Technologies, Matter, as well as Aeronautics, Space and Transport. Within each of these fields, research programs are developed by our scientists and regularly evaluated by renowned international experts. Their evaluation forms the basis for the programme-oriented funding that is allocated to Helmholtz research. Within the six research fields, Helmholtz scientists cooperate with each other and with external partners – working across disciplinary, organizational and national borders.

Promoting young academics

Helmholtz scientists, a high-performance infrastructure and modern and efficient research management are the ingredients to the Helmholtz Association‘s success and global impact.
Promoting young researchers is a major priority for the Helmholtz Association. Its qualification schemes for young researchers are geared mainly towards PhD students, postdocs and young managers. The Helmholtz Association has set high standards for its talent management. Its strategy begins with targeted recruitment of highly qualified staff at all levels, followed by comprehensive support aimed at further developing their potential. Ensuring equal opportunities is an essential element in all talent management activities undertaken by the Helmholtz Association.

The Helmholtz Graduate Schools and Research Schools at almost all Helmholtz Centres provide doctoral students with the general and specific skills and training they need, as well as ample opportunity to network with other working groups. The period following a doctorate is decisive in determining the direction and success of a scientific career. For this reason, we are about to establish Career Centers for postdoctoral researchers in the Helmholtz centres and a mentoring programme for especially gifted PostDocs in order to foster career orientation. This equips young researchers with the skills they need to go on to head a Helmholtz Young Investigators Group, for example. As a Young Investigator Group leader, junior scientists can independently set up their own group to conduct research in their specialist field.

Within its talent management strategy, the Helmholtz Association pays special attention to the increased recruitment of talented female scientists both from Germany and abroad. To this end, there are currently two funding programs supporting this policy Funding of first-time appointments of excellent women scientists (W2/W3)’ and ‘Funding to recruit top-level international women scientists (W3)’.

The increasing complexity of the content, structures and framework conditions of scientific work today requires researchers to organise their projects, their employees and, of course, themselves in a highly professional and effective way. In response to these demands, we have set up the Helmholtz Management Academy to provide junior leaders in science with professional management training. Furthermore, the Helmholtz network provides a platform for the alumni of the Helmholtz Management Academy and Mentoring programme to come together and share their experiences of leadership, career development and lifelong learning.
