Job Description
The German Climate Computing Centre (DKRZ) is the central simulation and data processing facility for the German climate and Earth system modelling community and one of the leading institutions in this field worldwide. DKRZ not only operates supercomputers of the highest performance class and one of the largest data and archive systems but also participates in many national and international projects aimed at improving the software and infrastructure for climate modelling. Here we are offering a position as
HPC programmer (all genders)
Tasks
We are looking for new colleagues who are enthusiastic about high performance computing and the development of research software. Do you enjoy working in a team that improves modern climate models Do you have experience in adapting software for use on existing and future supercomputers Then DKRZ is the right place for you.
The latest generation of HPC systems (often with graphics processors as accelerators) are essential for high-resolution climate simulations. Implementing the models is challenging because these codes have grown over decades and are constantly being supplemented with new components. Climate models which are still mainly written in Fortran and use the OpenACC standard must therefore be optimised and modernised. It is obvious that this affects both the software engineering and the underlying programming language and parallelisation approach. Adaptation to the respective HPC environment at DKRZ is also being continuously optimised e.g. by evaluating new compilers. You will work with international teams of experts consisting of Earth system researchers and computer scientists but also directly with compiler and hardware providers. You will implement the tasks for our users so that climate simulations can run as efficiently as possible on DKRZ systems.
Qualifications / Experiences
- Academic degree with a background in computational science applied mathematics or equivalent training and knowledge
- Strong experience in parallel programming for HPC systems (MPI OpenMP)
- Experience in GPU programming using standards like CUDA HIP or OpenACC
- Confident handling of tools such as Git Spack shell scripting
- Very good communication skills and knowledge of English
- And of course you should enjoy programming and working with state-of-the-art supercomputers
Employment conditions
We offer work in interdisciplinary teams and excellent connections to national and international research networks. In addition to specific implementation and support requirements from our users and project partners your work will be characterised by the freedom to work creatively at the interface between applied computer science and the development of scientific applications. Participation in international conferences project meetings and hackathons enable further training and presentation of your own results.
We are based in Hamburg but want to create a suitable working environment by offering flexible working hours and location (up to 100% work from home within Germany). Remuneration will be based on the candidates qualifications according to TVD-Bund. You can ideally start in August 2025 but the exact starting date can be agreed individually. The position is initially limited to five years.
Interested applicants are requested to compile a single pdf document containing a cover letter a detailed CV and any additional documents (e.g. professional references).
Application deadline: Open until filled. Priority will be given to applications received by 31 June 2025.
