We are looking for a hands-on storage engineer to operate and maintain the Ceph-based storage services supporting our on-premises Kubernetes and OpenShift platform. The role focuses on operating and improving production storage services, including monitoring, maintenance, upgrades, capacity management, hardware replacement, performance troubleshooting, and failure recovery.

Responsibilities:

- 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.

Requirements:

- Experience developing or operating distributed-storage platforms.

- Strong Linux systems administration and troubleshooting skills.

- Strong understanding of distributed-storage concepts, including quorum, data placement, replication, failure domains, recovery, rebalancing, and block, file, or object storage.

- 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.
