Samuel Just is a Senior Technical Staff Member with 15 years of experience focused on distributed storage, currently based in Glendale, California. He has held senior engineering roles at IBM, Red Hat, and Salesforce and is a long-time contributor to the Ceph project, working on core OSD, Crimson Seastore, and the ceph/teuthology test suite. His work blends backend systems design, debugging and refactoring of storage internals, and improving test automation and reliability for one of the most widely used open-source distributed storage platforms. Samuel's background in CS and mathematics from Harvey Mudd underpins a pragmatic, detail-oriented approach to data integrity and snapshotting challenges at scale. Not obvious from titles: he frequently tackles test-framework and scheduling complexities as well as low-level cache and object-data handling, bridging QA and systems engineering.
