Ceph Cluster Development Engineer (C++ Focus)

Job description

We are seeking a highly skilled Ceph Cluster Development & Operations Engineer with strong expertise in C++ systems programming to design, extend, and maintain enterprise-scale Ceph distributed storage clusters. The role involves deep development in Ceph core subsystems (RADOS, OSD, RGW, MDS), performance optimization, and operational excellence across multi-site, multi-zone architectures.

You will work closely with system architects, SREs, and cloud infrastructure teams to ensure the reliability, scalability, and security of mission-critical storage systems deployed across multiple data centers and Kubernetes environments.

Key Responsibilities

• Design, build, and operate large-scale Ceph clusters including RADOS, RGW, RBD
• Contribute to or extend Ceph core components written in C++ (e.g., OSD, RGW, librados, BlueStore, MGR modules).
• Profile and optimize performance across network, disk I/O, and replication layers (PG placement, CRUSH rules, BlueStore tuning).
• Develop automation and tooling for cluster lifecycle management (deployment, upgrades, scaling, failover, and recovery).
• Integrate Ceph with Kubernetes (via Rook-Ceph, CSI drivers) and CI/CD pipelines for continuous delivery.
• Implement and validate multi-site replication and disaster recovery architectures for high availability.
• Develop and maintain secure storage solutions using dm-crypt, KMS integration, and CephX authentication.
• Build observability pipelines using Prometheus, Grafana, and custom exporters for metrics and health analytics.
• Write and maintain SOPs, automation scripts, and system documentation to support production-grade operations.
