This position offers the opportunity to work at the intersection of basic research, applied research, and the development of sustainable research data infrastructures.

  • Leading a research group that develops and investigates innovative methods and infrastructures for FAIRness and the AI-supported use of research data and metadata in the social sciences
  • Collaborating with national and international research data infrastructure initiatives (in particular NFDI and EOSC), as well as other teams and departments at GESIS 
  • Leading research projects in areas such as natural language processing, information retrieval, knowledge graphs, and/or machine learning Securing competitive external funding 
  • Coordinating infrastructure activities of the team and the transfer of research findings into innovative research infrastructures
  • Presenting research findings and infrastructure innovations at academic conferences and within interdisciplinary networks and communities

Your profile:

  • Completed academic university degree (Master’s or equivalent) and a completed or well-advanced doctoral degree / PhD in computer science or related fields
  • Relevant scientific expertise in one or more of the following areas: natural language processing, information extraction, information retrieval, knowledge graphs, and machine learning
  • Experience in managing projects and teams, as well as in securing and leading externally funded projects
  • Excellent command of English (spoken and written); knowledge of German is a plus (we support and expect you to achieve C1-level proficiency in German within the first three years)
  • Strong communication and problem-solving skills, as well as the ability to take initiative

Our Benefits:

  • A rapidly growing, international, and interdisciplinary work environment with close ties to regional and international research institutions in related fields 
  • Access to large research datasets, e.g., web and social media crawls
  • Flexible working hours and regulations for mobile working
  • Very good conditions for reconciling work and family life, e.g. subsidies for childcare for children who have not yet attained the age of compulsory schooling
  • Holistic company health management and discounted participation in the university's sports programme 
  • Generous support for your pension provision through a direct insurance plan
  • Promotion of your skills through further training measures
