Highlights

  • I'm hiring a data scientist to work for 12 months on mapping the geographic origin of Free/Open Source Software (FOSS) developers in various FOSS package ecosystems. See job description (in French) for details. Contact me via email for inquiries and applications.
  • I'm hiring a PhD student to work for 3 years on the thesis topic CodeLedger: tracking the provenance of critical open source components. The work will consist on enabling tracking the state of the Software Heritage archive in a distributed setting (e.g., with archive mirrors in place) and to allow using it for securing information about the provenance and integrity of Free/Open Source Software (FOSS) components that are part of the global software supply chain. See topic description for details. Contact me via email for inquiries and applications.
  • I'm hiring a postdoctoral researcher to work for 12 months on the extension and exploitation of the Software Heritage compressed graph (AKA swh-graph). Such a graph approximates the development history of all publicly available source code and is used in production to exploit and analyze at scale the largest version control system graph in the world (~20 billion nodes, ~200 billion edges).
