• Extensive practical experience with GitHub and common development workflows
• Excellent knowledge of modern programming languages, especially Python

The following qualifications are also expected:

• Proven skills in software development and the ability to develop mature software components beyond pure research prototypes
• Extensive experience with data management technologies, especially semantic data management involving ontologies and OWL-based knowledge graphs
• Experience and interest in working in research teams
• Collaboration with other research groups in joint research projects

Desirable additions to your profile:

• Knowledge of human-computer interaction and data visualization
• Basic knowledge in the fields of engineering and materials science
• A PhD is an advantage, but not a requirement

What we offer:

Our mission is to keep rethinking and innovating the provision and use of research data and information. In TIB's Research and Development Department, you have the opportunity to advance your career in a sizable, dynamic and excellent environment. We provide a scientifically and intellectually inspiring environment with an entrepreneurial mindset embedded in a leading technical university and one of the largest technical information centers being part of the Leibniz Association. TIB collaborates closely with the L3S Research Center at Leibniz University Hannover, one of the world's leading research institutes in the field of Web & Data Science, within the Leibniz Joint Lab Data Science & Open Knowledge. Last but not least, we attach great importance to an open, creative and fun work atmosphere.

Furthermore, we offer:

• A job in the public service oriented towards the common good on the basis of the collective agreement for the public service of the German states (TV-L) with a salary in pay scale group 13 TV-L.
