Description

  • Design, build, and maintain backend systems and APIs for Wikidata’s query infrastructure.
  • Improve the reliability, observability, and automation of the Wikidata Query Service and related data pipelines.
  • Integrate Wikidata Platform services with other Wikimedia systems and data sources.
  • Collaborate with SRE, data engineering, and product teams to ensure stability and scalability.
  • Monitor production systems, respond to operational incidents, and resolve performance bottlenecks.

  • Experience with knowledge graphs or RDF/SPARQL is preferred.
  • Familiarity with streaming data systems such as Kafka or Flink is preferred.
  • Comfort with CI/CD pipelines and containerization tools such as Docker and Kubernetes is preferred.
  • Experience in open source or open knowledge communities is preferred.
  • Familiarity with Wikimedia technologies, Wikidata, or MediaWiki is preferred.
  • Ability to overlap working hours with UTC+1 to UTC-5, with team overlap between 14:00 UTC and 17:00 UTC.
