We are not developing a new distributed-storage solution. Candidates with experience developing or operating distributed-storage platforms are encouraged to apply.

You will work closely with the Kubernetes platform, network, infrastructure, and application teams to keep storage services reliable and supportable.

What to Expect

• Operate and maintain Ceph and OpenShift Data Foundation environments.
• Monitor cluster health, capacity, latency, throughput, placement groups, and device status.
• Manage OSD and node replacement, recovery, rebalancing, backfill, scrubbing, and routine maintenance.
• Diagnose degraded placement groups, slow operations, quorum issues, device failures, and network-related storage problems.
• Plan and perform Ceph/ODF upgrades, expansion, patching, and configuration changes.
• Support block and shared-file storage through ODF, Ceph CSI, RBD, and CephFS.
• Troubleshoot persistent-volume provisioning, attachment, mounting, expansion, and performance issues.
• Maintain dashboards, alerts, runbooks, capacity plans, and recovery procedures.
• Test recovery from disk, node, service, and network failures.Coordinate server, disk, firmware, and network maintenance with infrastructure teams.
• Participate in production incident response and root-cause analysis.

What we are looking for

• Hands-on experience with Ceph
• Experience with storage monitoring, capacity planning, upgrades, expansion, and component replacement.
• Experience benchmarking storage workloads and analysing performance bottlenecks.
• Ability to diagnose storage issues across software, Linux, networks, and physical hardware.
• Knowledge of HDD, SSD, NVMe, HBA, firmware, and storage-network considerations.
• Automation experience using Ansible, Python, shell, or similar tools.
• Backup, snapshots, replication, and disaster-recovery operations.
