Introduction
IBM's Ceph[1] engineering organization is looking for a senior software engineer to join the RBD team. In this role you will collaborate with our worldwide Ceph engineering team to develop and enhance RBD[2], the file system component of the Ceph software-defined distributed storage system. You will design and 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.
RBD comprises a wide-ranging software suite including Linux kernel and userspace clients, optional caches, and disaster recovery daemons, in addition to higher-level APIs for integrating with other systems (OpenStack, OpenShift, NVMeoF, etc). As a member of the RBD 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 storage system, such as enhanced consistency groups, disaster recovery, and multi-tenant capabilities.
