In a nutshell: DataLad (https://www.datalad.org/) was initially inspired by Debian as a unified distribution for software, and git-annex (developed by Joey Hess, a former DD, the original author of debian-installer, debhelper etc) to provide unified data access to disconnected data hosting portals.
Since its inception in 2013, DataLad became not only a distribution but also a complete Data Management platform. Through all these years, we have been actively collaborating with Joey Hess so lots of work was done directly at git-annex level, so we do not re-invent the wheel in DataLad and so that there is benefit to the wider git-annex based ecosystem of solutions.
Both "principle investigators" of the DataLad (me and Michael Hanke) are Debian developers, and we strive to ensure that DataLad and its dependencies are properly integrated within Debian.
So, if you like Git, interested in git-annex, and verse in Python -- this position might be a great fit for you. Please apply at https://searchjobs.dartmouth.edu/postings/57791
PS There is also a similar satellite job ad https://searchjobs.dartmouth.edu/postings/57749 for a position which will not be as deeply involved with DataLad, but with other projects such as https://dandiarchive.org/ etc (all is FOSS).
