IBM'sCeph[1] Engineering organization is looking for a Senior Software Engineer to join theCephFS team. In this role you will collaborate with our worldwideCeph engineering team to develop and enhanceCephFS[2], the file system component of theCeph software-defined distributed storage system. You willdesignand implement new capabilities and features to enable new use cases while improving scalability, performance and efficiency. You will participate in a vibrant and active open source community[3] to deliver enterprise-quality software.
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 withCeph'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 theCephFS 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.
You will work remotely with a worldwide team so communication is key. You will collaborate with others using modern open sourcetoolsincluding git (and GitHub), Jenkins,Redmine, and community-developed testing and validationtools.
Roles andResponsibilities of a Senior Software Engineer in IBM'sCeph Engineering Organization:
Work closely with the globalCeph open-source, multi-company engineering team to develop and enhanceCephFS, the file system component of theCeph software-defined distributed storage system. You will collaborate with other developers and users by attending online meetings, participating in email lists and online chat rooms, preparing written documentation, and giving presentations about your work. You will be expected to work proactively with other team members and the community to develop your own knowledge, and to be ready to mentor new contributors as you develop expertise.
Contribute to the development ofCephFS bydesigning and implementing new functionalities that enable innovative use cases. This includesdesigning 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 ourC++-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 withinCeph's "RADOS" distributed object store.
