HPC Researcher - AI Support on Exascale

titel

Are you a researcher in science, technology, engineering, or math with a deep technical interest and a passion for AI? Join us on the road to Exascale! Our "Simulation and Data Lab Applied Machine Learning" applies Machine Learning at the largest scales. As part of our exciting projects we develop novel AI methods for scientific research, collaborating with other scientists and their data. In parallel, we work on scaling AI methods for images, text, and other modalities. We are especially excited about JUPITER, Europe’s first Exascale computer, currently being installed in Jülich. Over the coming years, we will develop algorithms to scale up ML workflows on this groundbreaking machine. We will train Large Language Models and powerful Diffusion Models, building new tools to drive scientific breakthroughs.
