Senior Site Reliability Engineer - Ceph / On-Prem Cloud Storage

Deine Rolle im Team

Unsere Erwartungen an dich

Qualifikationen

• You know the Ceph fundamentals from real-world operations: CRUSH, pools and placement groups, replication vs. erasure coding, BlueStore, scrubbing, recovery and backfill under load.
• You have managed storage infrastructure end to end, from the physical layer with drives, firmware, BIOS, controllers and hardware diagnostics through rebalancing, host drains, capacity expansion and hardware generation migrations.
• You are comfortable using Kubernetes as a control plane, not only as a workload runtime, and understand operators/controllers, custom resources, reconciliation and GitOps.
• You can also move confidently around OpenStack and debug issues involving Ironic, Neutron, Nova or Glance when needed.
• You have dealt with situations where durability really matters - such as degraded or near-full clusters, recovery under load or split-brain conditions - and you are used to making changes in a staged, evidence-based and reversible way.
• You have strong Linux and bare-metal skills, understand the block layer, filesystems and I/O behaviour, and are comfortable working with Ansible, Terraform and GitOps.
• AI-assisted engineering is already part of your day-to-day work.
• You work autonomously, bring a strong sense of ownership, and are comfortable debugging problems where the actual root cause may sit somewhere between storage, networking, Kubernetes and OpenStack.
• You would rather verify what is happening from evidence than assume how the system should behave.
• We work in an international environment in English, so you should feel comfortable discussing technical topics, documenting decisions and working with the team in English.

Erfahrung

• Several years of hands-on experience as an SRE, Storage Engineer or Platform Engineer running production storage infrastructure, with solid experience deploying, operating and debugging Ceph in production.
• You have practical experience with LLMs and agentic tools and know where they can meaningfully support development, testing, reviews or operations.
• Ideally, you also bring experience with RGW / S3, RBD mirroring, CephFS or ceph-csi, deeper OpenStack storage integrations and Go and/or Python.
• Experience around VLAN/BGP, storage performance tuning, NVMe/BlueStore, observability, data protection, encryption, auto-remediation, security baselines or multi-site storage is also relevant for the role.
