Tech­ni­sche Infor­ma­ti­ons­bi­blio­thek (TIB) - Pro­gram Area C, Rese­arch and Devel­op­ment

TIB, being part of the Leib­niz Rese­arch Asso­ci­ation, is with around 600 employ­ees one of the lar­gest tech­nical inform­a­tion cen­tres in Ger­many, hav­ing three main func­tions:
1. Act­ing in the capa­city of the Leib­niz Inform­a­tion Centre for Sci­ence and Tech­no­logy, our for­ward-look­ing ser­vices secure the infra­struc­tural require­ments for pro­vid­ing rese­arch­ers in sci­ence and indus­try with high-qual­ity inform­a­tion and lit­er­at­ure.
2. Car­ry­ing out cut­ting edge rese­arch to fur­ther expand TIB’s role as a Ger­man inform­a­tion centre for the digit­isa­tion of sci­ence and tech­no­logy.
3. Offer lib­rary ser­vices for the Leib­niz Uni­ver­sity Han­nover.

Sci­entific Soft­ware Engin­eer / Onto­logy Engin­eer (m/f/d)

Pro­gram Area C, Research and Devel­op­ment, Lab Linked Sci­entific Know­ledge

Working field:

Your chal­lenge
The Lab Linked Sci­entific Know­ledge devel­ops tools and meth­od­o­lo­gies to sup­port sci­ent­ists in the digit­iz­a­tion of their research. This includes tools to doc­u­ment research activ­it­ies and the acquis­i­tion, pro­cessing, ana­lysis, stor­age, pub­lic­a­tion and re-use of research data.

Your tasks will be the devel­op­ment of know­ledge man­age­ment sys­tems and tools for semantic annota­tion of data using onto­lo­gies. Other duties will include con­vert­ing data to RDF as well as stor­age, retrieval, and visu­al­iz­a­tion. We expect you to be able to inde­pend­ently install, run, and main­tain neces­sary soft­ware to build semantic­ally annot­ated data repos­it­or­ies. This requires solid know­ledge of vir­tu­al­iz­a­tion plat­forms such as Docker as well as data­bases such as Vir­tu­oso, Apache Jena, Mon­goDB and oth­ers.

With your work in an inter­dis­cip­lin­ary team, you will make an import­ant con­tri­bu­tion to inform­a­tion infra­struc­ture pro­jects of Col­lab­or­at­ive Research Cen­ters from the engin­eer­ing sci­ences as well as NFDI4Chem, the Chem­istry Con­sor­tium in the National Research Data Infra­struc­ture (NFDI).

Your tasks will focus on
  • Devel­op­ment, cur­a­tion, and integ­ra­tion of onto­lo­gies for chem­istry and engin­eer­ing.
  • Devel­op­ment of con­trolled vocab­u­lar­ies and clas­si­fic­a­tions to stand­ard­ize data for research data man­age­ment (RDM).
  • Devel­op­ment of semantic tools for hand­ling onto­lo­gies and seman­ti­fic­a­tion of research data.
  • Devel­op­ment of know­ledge man­age­ment sys­tems in the con­text of inform­a­tion infra­struc­ture pro­jects of col­lab­or­at­ive research centres from engin­eer­ing sci­ences.
  • Com­munity out­reach and joint devel­op­ment and cur­a­tion of onto­lo­gies with domain experts and onto­logy users.
  • Organ­iz­a­tion of onto­logy work­shops for and with the sci­entific com­munity.


Your qual­it­ies
The suc­cess­ful can­did­ate will have exper­i­ence in com­puter sci­ence, chem­istry or engin­eer­ing sci­ences. You are famil­iar with con­trolled vocab­u­lar­ies and onto­lo­gies to describe domain con­cepts. Excel­lent verbal and writ­ten com­mu­nic­a­tion skills are essen­tial in order to col­lab­or­at­ively develop onto­lo­gies together with the sci­entific com­munity dur­ing work­shops and dis­cus­sions. You should be able to think cre­at­ively, grasp new know­ledge quickly, and be inter­ested in innov­at­ive soft­ware sys­tems and in mas­ter­ing com­plex chal­lenges.

  • Com­pleted uni­versity degree (Bach­elor’s or Mas­ter’s degree) in a rel­ev­ant field of study such as com­puter sci­ence, engin­eer­ing sci­ences, chem­ical inform­at­ics, bioin­form­at­ics, inform­a­tion sci­ences or com­par­able.
  • Excel­lent know­ledge of mod­ern pro­gram­ming lan­guages (espe­cially Python, Java, PHP as well as JavaS­cript and HTML) and mod­ern soft­ware devel­op­ment meth­ods.
  • Proven skills in soft­ware devel­op­ment in a team.
  • Exper­i­ence in devel­op­ing, integ­rat­ing and pub­lish­ing con­trolled vocab­u­lar­ies, ter­min­o­lo­gies and onto­lo­gies
  • Know­ledge in onto­logy devel­op­ment and with core semantic tech­no­lo­gies (RDF, OWL, SPARQL).
  • Solid exper­i­ence in using RDF and SPARQL for data mod­el­ing and query­ing.
  • Exper­i­ence in know­ledge rep­res­ent­a­tion and logic, semantic tech­no­lo­gies, and web engin­eer­ing.
  • Know­ledge and hands-on exper­i­ence with onto­logy tools such as Pro­tegé, Web­Pro­tegé or WebVOWL.
  • Excel­lent verbal and writ­ten com­mu­nic­a­tion skills.

The fol­low­ing will be con­sidered an advant­age
  • Exper­i­ence with Wiki­Me­dia soft­ware envir­on­ments, espe­cially Semantic Medi­aWiki.
  • Pro­fi­ciency in the Ger­man lan­guage.
  • Exper­i­ence with CI/CD work­flows in Git­Lab.
  • Exper­i­ence in DevOps and/or sys­tem admin­is­tra­tion.
  • Famili­ar­ity with and interest in sci­entific data and metadata man­age­ment.
  • Know­ledge of tools and ser­vices for research data man­age­ment.
