Scientific Software Engineer (m/f/d)

The National Research Data Infrastructure (NFDI) is an outstanding infrastructure initiative for the science communities in Germany with the aim to harness the great potential of Research Data as a valuable resource for science and research. Since October 1st 2020, the first round of NFDI consortia is funded for a period of five years, with the option of a five-year extension. TIB will play a key role in shaping the NFDI from the very beginning.

Within this network the Technische Informationsbibliothek (TIB) – Leibniz Information Centre for Science and Technology – is looking to employ a

Scientific Software Engineer (m/f/d)

to join the Lab Linked Scientific Knowledge at the earliest possible opportunity.

The position is initially limited to 3 years with envisioned extension in the context of NFDI. The regular weekly working time is 39.8 hours (full-time). The position is only suitable for part-time work to a limited extent. The remuneration is based on pay scale group 13 TV-L.

You will work in a team to build a national research data infrastructure for chemistry in Germany (NFDI4Chem). NFDI4Chem will be a distributed infrastructure project with more than 30 FTE from IT and science and operates in the wider context of the NFDI in collaboration with eventually 29 further consortia from all areas of science. A detailed project description of NFDI4Chem can be found at

Your challenge
The vision of NFDI4Chem is the digitalisation of all key steps in chemical research to support scientists in their efforts to collect, store, process, analyse, disclose and re-use research data. This overall goal is addressed by several task areas (TAs). You will be assigned to TA6 Synergies, which is responsible for the coordination of the cross-cutting topics within the NFDI, including cross-domain metadata standards, semantic data annotation and cross-domain mapping of ontologies, as well as the provision of terminology services. You will work closely together with developers, scientists and infrastructure experts from over 25 university and non-university research institutions in a dynamic and inspiring environment. A special focus will be on the collaboration with TA3 Repositories and TA4 Standards.

Your tasks will focus on

  • Development of a data portal for the virtual environment of federated NFDI4Chem repositories and provision of an integrated view of the data sets archived by these repositories
  • Semantic linking of data catalogues and repositories, based on an extendable and adaptable vocabulary framework
  • Development of a metadata harvesting of repositories in NFDI4Chem taking into account different data and metadata standards, APIs, file formats, license information, archiving and publication guidelines and terms of re-use

Your qualities
You are equally experienced in frontend and backend development. Your competence is rooted in web software engineering, but you are also familiar with API design and databases. You should be able to think creatively, grasp new knowledge quickly, be able to design and develop innovative software systems and be interested in mastering complex challenges.

  • Working knowledge in the development and use of web services (REST APIs, SOAP)
  • Experience with core semantic technologies (RDF, OWL, SPARQL)
  • Experience with graph databases (neo4j)

Desired additions to your profile

  • Experience in development of controlled vocabularies and classifications is a plus.
  • Familiarity and interest in scientific data and meta-data management
  • Familiarity in Natural Language Processing, Artificial Intelligence, Data Analytics or Digital Libraries is an asset.
  • Knowledge of Research Data Management Tools and Services
  • Proficiency in German is a plus.

The Lab Linked Scientific Knowledge is embedded into the Research Group Data Science & Digital Libraries. TIB’s Research and Development Department offers a scientifically and intellectually inspiring work environment with an entrepreneurial mindset embedded in a leading technical university and one of the largest technical information centres being part of the Leibniz Association.

The research department at the TIB is relatively young and offers many opportunities. It is our vision to rethink the representation and provision of data and information and to organize them in an Open Research Knowledge Graph (ORKG) in the future. There is a close cooperation with the L3S Research Centre 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 and creative working atmosphere in which it is fun to work.

Furthermore, we offer

  • Funding for necessary equipment, conference and research visit travel
  • Candidates will work in the context of a national research and innovation project
  • A portfolio of technology components to build on, including ORKG,, TIB AV-Portal, and other
  • A modern workplace in a central location of Hanover with a collegial, attractive and versatile working environment
