Design and architect large-scale production Ceph clusters, including CRUSH topology, failure-domain modeling, replication and erasure-coding strategies, storage hardware selection, and data placement architecture.
Lead fleet-wide capacity planning, performance modeling, and hardware qualification across 80+ production clusters comprising 20,000+ OSDs and 300 PB of raw storage.
Own major platform upgrades and migration initiatives, including Ceph releases, OpenStack integrations, and large-scale storage modernization efforts.
Drive resolution of the most complex cross-functional production incidents spanning storage, networking, virtualization, and compute systems.
Establish automation, operational standards, and reliability practices that improve platform scalability, reduce toil, and increase engineering efficiency across the storage organization.
7+ years designing, operating, and scaling distributed storage platforms, including deep hands-on ownership of production Ceph environments.
Expert-level Ceph knowledge including CRUSH maps, placement groups, OSD architecture, MON/MGR/MDS subsystems, RGW, CephFS, RBD, replication, and erasure coding.
Qualification
Required
Proven experience designing storage architectures and performing capacity planning, durability analysis, performance optimization, and failure-domain modeling at scale.
Experience leading major storage platform upgrades, migrations, and modernization programs from planning through production execution.
Strong automation and software engineering skills using Python and/or Go, combined with Infrastructure-as-Code and orchestration frameworks such as Terraform, SaltStack, and Ansible.
Deep expertise with advanced Ceph technologies including RGW Multisite, RBD Mirroring, CephFS at scale, BlueStore tuning, and erasure-coding optimization.
OpenStack storage architecture experience including Cinder, Swift, Manila, Nova, and Neutron integrations with Ceph.
Experience evaluating and integrating large-scale storage technologies such as NetApp, Isilon, Pure, VAST, Weka, DDN, and AI/HPC storage platforms.
Contributions to the Ceph community through upstream development, code reviews, bug fixes, architecture discussions, or open-source storage initiatives.
