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.
• Collaborate with upstream Ceph community or maintain in-house forks for feature development and bug fixes. Qualifications Required Skills

• Strong proficiency in C++ (C++11 or later), with experience in large-scale distributed systems or kernel-adjacent development.
• Deep understanding of Ceph architecture and its core components: MON, OSD, MGR, RGW, MDS, and CRUSH maps.
• Proficient in Linux systems programming, debugging (gdb, perf, valgrind), and performance profiling.
• Experience with Python or Go for tooling and automation.
• Strong foundation in data replication, erasure coding, and consistency models in distributed storage.
• Hands-on experience with Kubernetes, Rook-Ceph, Helm, Ansible, and related DevOps tools.
• Familiarity with TCP/IP, HTTP/S3 APIs, block storage (RBD/iSCSI), and object storage semantics.
• Ability to conduct root-cause analysis and lead performance investigations under production environments. Preferred Skills
• Contributions to the Ceph open-source project or prior experience modifying Ceph source code.
• Experience with multi-site replication, object versioning, compliance retention, or legal hold features.
• Background in distributed storage systems, file systems, or cloud storage platforms.
• Familiarity with containerized environments, network virtualization, and cloud-native observability stacks.
• Excellent technical documentation and communication skills in English.
• Strong oral and written communication skills in English. Exceptional ability to articulate messages in English.
