CephFS comprises a wide-ranging software suite including Linux kernel and userspace clients, a clustered userspace metadata server, and a messaging layer for storing data with Ceph’s native object store (“RADOS”), in addition to higher-level APIs for integrating with other systems (OpenStack, OpenShift, an NFS-Ganesha cluster, Samba, etc). As a member of the CephFS engineering team, you will have the opportunity to learn and work in many of these areas according to your experience and technical background. Candidates will be excited to develop new distributed algorithms to build out end-user features of the filesystem, such as instant cloning, file overlays, and coherent snapshots across multiple clients with a coherent distributed cache.

Contribute to the development of CephFS by designing and implementing new functionalities that enable innovative use cases. This includes designing new distributed algorithms, implementing them across clients and servers, and writing automated test cases to demonstrate they work. You will also identify and fix bugs and propose performance enhancements. This will involve work across our C++-language Metadata Server cluster and userspace clients, our Linux in-kernel client (which you may either develop on your own, or arrange with our kernel maintainers), and our messaging layer for storing data within Ceph’s “RADOS” distributed object store.
