Job summary

Optimum Solutions Pte Ltd is seeking a hands-on storage engineer to operate and maintain Ceph-based storage services supporting our on-prem Kubernetes and OpenShift platform. You will monitor, maintain, upgrade, and troubleshoot storage, manage capacity, perform hardware replacements, and coordinate with infrastructure teams to keep storage reliable.

This role emphasizes production operations rather than building new storage tech, with opportunities to optimize performance and disaster recovery

Qualifications

Hands-on Ceph experience required.
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 hardware.
Knowledge of HDD, SSD, NVMe, HBA, firmware, and storage-network considerations.
Automation experience using Ansible, Python, shell, or similar tools.
Experience with backup, snapshots, replication, and disaster-recovery operations.

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.
