We are hiring an experienced Ceph Engineer on behalf of our Client to work with our Client’s engineering team, which develops and runs external SAP Cloud Infrastructure services for their customers. These cloud services are based on OpenStack, a flexible open-source cloud computing platform. In addition to developing new cloud solutions, the work entails operating a secure, stable, and robust cloud platform. To that end, the team runs monitoring services organized into support groups that provide 24h follow-the-sun troubleshooting support, operates a flexible and scalable control plane, and adheres to state-of-the-art security standards.

Role Description

As a Ceph Developer, you will work on the core components of the Ceph storage platform, with a focus on performance optimization, feature development, and long-term maintainability. You will contribute to both upstream Ceph and internal forks, designing and implementing enhancements across modules like RGW, RADOS, RBD, and CephFS. This role combines deep system-level development with the operational realities of running Ceph in large-scale, Kubernetes-driven cloud-native environments.

• Optimize storage system performance, scalability, and reliability
• Troubleshoot distributed storage issues and debug low-level system behavior
• Participate in upstream Ceph development and community discussions
• Integrate Ceph with Kubernetes via Rook and CSI drivers
• Monitor and improve system observability using telemetry and metrics
• Plan and execute development tasks using Agile methodologies
• Contribute to technical documentation, design reviews, and internal knowledge sharing

Required Skills

• Strong proficiency in C++ and Python (5+ years)
• Hands-on experience with Ceph (any of RGW, RADOS, RBD, CephFS)
• Solid understanding of Linux internals (I/O, memory management, threading)
• Familiarity with Kubernetes, Rook, and Ceph CSI drivers
• Experience with Git, GitHub, and CI/CD pipelines
• Exposure to large-scale infrastructure or cloud-native environments
• Proficiency with observability tools (Prometheus, Grafana, etc.)

Optional Skills

• Contributions to open-source projects (especially Ceph)
• Experience with cloud platforms: AWS, Azure, or OpenStack
• Familiarity with performance profiling tools and storage benchmarks
• Knowledge of S3 and Swift protocols and object storage semantics
