PostDoc Research Scientist* Large Language Model for Problem Solving

Оccupation: Computer scientist


The Fraunhofer-Gesellschaft (www.fraunhofer.de) currently operates 75 institutes and research institutions in Germany and is one of the leading organisations for application-oriented research. Around 32 000 employees develop the annual research volume of 3.4 billion euros.

As part of the largest organization for application-oriented research in Europe, Fraunhofer IAIS, based in Sankt Augustin near Bonn, is one of the leading scientific institutes in the fields of artificial intelligence, machine learning and big data in Germany and Europe. With our more than 350 employees, we develop intelligent solutions for the optimisation of products, services, processes and structures, as well as the development of new digital business models for our supporters and customers from the economy.

In the Hybrid Intelligence (HI) department, we bundle the expertise of a dedicated team of scientists and work with partners from science and industry on innovative approaches and solutions for the current challenges in the application.

Our portfolio includes:

  • Machine learning solutions such as multi-agent systems and Recommender systems
  • the LLM Explore Hub for NLP applications
  • Textanonymization tools
  • Finetuning tool sets for large language models Conception and implementation of practical AI workshops

For our Finance and Legal Intelligence business, we are looking for an PostDoc Research Scientist at the next time.
