Research Software Engineer / Scientific Researcher (m/f/d)

Karlsruhe Institute of Technology (KIT) – The University in the Helmholtz Association In close partnership with society, KIT develops solutions for challenges – from climate change, energy transition and sustainable use of natural resources to artificial intelligence, balancing and an aging population. As The University in the Helmholtz Association, KIT unites scientific from insight to application-driven research under one roof – and is thus in a unique position to drive this transformation. As a University of Excellence, KIT offers its more than 10,000 employees and 22,800 students outstanding opportunities to shape a sustainable and resilient future. KIT – Science for Impact. We are looking for the Scientific Computing Center (SCC) as soon as possible and limited for up to 2 years for a Research Software Engineer / Scientific Researcher (m/f/d) The Scientific Computing Center is the Information Technology Center of KIT.

Earth system models (ESMs) are highly complex software systems that have often developed over several decades. In addition to the core model that com­putes meteorological processes, an ESM includes a wide range of specialized submodels - search as those for cloud microphysics or atmospheric chemistry - interconnected through well-defined interfaces. The computational demands of ESMs are immense, but their high degree of parallelism long-term climate simulations on modern HPC clusters. Continuously adapting these models to the latest hardware and software developments at ongoing challenge. Your responsibilities in this area will include the following tasks (in close collab-oration with domain scientists): Ensuring the sustainability of community ESM codes, and enabling the adoption of modern HPC systems Enabling and improving high-performance computing capabilities of ESM codes including performance optimization Contributing to porting ESM codes to heterogeneous HPC architectures, including GPU-accelerated systems Participation in model developments with regard to the further development of an improved simulation of the Earth system Participate in the NHR ESM community through software development support and user outreach Carrying out own research in atmospheric modeling, including running and analyzing ESM simulations Participating in scientific conferences and contributing to peer-reviewed publications

Degree (Master's level) and doctorate in atmospheric research, computer science, physics, engineering or a related field Strong knowledge in the programming languages Fortran, C++, and Python Solid background in build engineering, including Makefile development, compiler configurations, build optimization, and experience with Linux-based HPC clusters Good software development practices, including version control with Git, doc-umentation, and CI/CD workflows Substantial experience with distributed- and shared-memory parallelization using MPI and OpenMP. Additional background in development for heterogeneous architectures (e.g., CUDA or ROCm) is obtaining Familiarity with modern deep learning frameworks (e.g., PyTorch or Tensor-Flow) and contemporary AI models, search as transformer-based models or convolutional neural networks, is reform Strong communication and presentation skills and the ability and motivation to work effectively in a team Good written and spoken English skills; English language skills are an advantage
