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++ (5+ years)
Experience with Python
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

Project background
The engineering team develops and runs external SAP Cloud Infrastructure services used by our customers. These cloud services are based on Openstack, a flexible open-source cloud computing platform. It allows us to build and manage a complex cloud infrastructure, controlling virtual machines, storage, and networking resources. This platform lets us scale applications and efficiently manage our cloud environment to serve the individual use cases of our customers. In cases where Openstack does not ship a suitable solution to fulfill our customers’ demands we develop technical solutions to augment our current service offering wherever possible.
