The German Climate Computing Centre (DKRZ) is the central data processing facility for the German climate and Earth system modeling community and is one of the leading facilities in this area. DKRZ operates supercomputers of the highest performance class, modern high-performance clusters and graphics systems as well as one of the largest data and archive systems worldwide.

Subject to funding approval by the German Federal Ministry of Education and Research, we offer in the national ESM support team a position as

Project Assistance, part time (all genders)

High-performance computing (HPC) is the workhorse for Earth system modelling (ESM), providing new insights into Earth system processes to better understand global change and assess adaptation scenarios. Earth system models tend to become more accurate and trustworthy in the process, but the enormous changes in the HPC landscape in recent years have further complicated code adaptations and made them an ongoing task. These challenges posed by new heterogeneous HPC systems and the need for code refactoring are to be addressed jointly as part of a national ESM strategy.


While the scientific development of the ESM components has to be tackled in the home institutions, the technical challenges around HPC and software development can be addressed jointly. To this end, a national ESM support team will be formed. This team will help to efficiently apply resources, mobilise synergies, share insights and disseminate knowledge. Key points here are: direct HPC support for the ESM community; building expertise in HPC, workflows, modularisation and coupling of components; scalable diagnostics for ESM codes; training programs for the ESM community; and advancing the national ESM strategy.

Job description

This person will be responsible for project communication, workshop organisation, management of working groups and all technical needs to promote the community-wide acceptance of the national ESM support team.

Qualifications / Experiences

  • Affinity to Earth system science and/or scientific computing
  • Strong organisational skills and ability to work independently
  • Strong language skills in at least English and German

Employment conditions

As a member of the national ESM support team, you will have the opportunity to work in a flexible academic environment, follow your own initiative, build strong collaborations within the German Earth system modelling community, and establish extensive collaborations with HPC centres.
The German Climate Computing Centre (DKRZ) is the central simulation and data processing facility for the German climate and Earth system modelling and is one of the leading facilities in this area. The new national ESM support team will be closely integrated into the existing HPC support structures and can thus benefit directly from existing knowledge and experience. Since the Jülich Supercomputing Centre (JSC) will also be joining the support team with two additional positions, there will also be access to the most powerful supercomputer in Europe.
For all positions we expect good to excellent English skills, as this is our working language. Due to the intended concept of changing support tasks, the ability to work in a team in an interdisciplinary environment and willingness to travel is a must-have.
Hamburg is envisaged as the place of work for coordination and assistance, with a high proportion (up to 100%) of work from home possible.
The coordination (full time) and assistant (part time by arrangement) positions will start at the end of 2021. The start date can be arranged individually and the positions are initially limited to 36 months.
Payment will be in accordance with the German public service positions (TVöD E9 for the assistance), including extensive social security plans. The conditions of employment follow those of the German civil service.
DKRZ strives for gender and diversity equality. We welcome applications from all backgrounds. Handicapped persons with comparable qualifications receive preferential status.
