Summary

Founded in 2008, HathiTrust is a not-for-profit collaborative of academic and research libraries. HathiTrust offers reading access to the fullest extent allowable by U.S. copyright law, computational access to the entire corpus for scholarly research, and other new services based on the combined collection. HathiTrust members steward the collection — the largest set of digitized books managed by academic and research libraries. For more information on HathiTrust, please visit www.hathitrust.org.

HathiTrust is looking for an experienced developer to help develop data workflows for large-scale digital library systems. HathiTrust has a repository of over a petabyte of data comprising about 17.6 million digitized books. There is an Apache Solr index comprising over 12 terabytes of full text from these books and a separate index with library catalog metadata (MARC records) for each item. We manage a variety of metadata in MariaDB and in MongoDB including information about holdings from member libraries, copyright and licensing information, US federal government documents, and more. We use in-house software written in the Perl and Ruby programming languages to manage indexing and search processes for this data, much of which is publicly available in HathiTrust's GitHub. Our infrastructure runs in multiple Linux environments, including virtual machines and containerized with Docker and Kubernetes.

As the Data Engineer you will work with developers, librarians, and other partners to modernize and improve indexing, search, and analysis for these kinds of data to enable improvements to HathiTrust's websites and applications. You will report to the HathiTrust Enterprise Technology Team Lead.
