Our Object Storage platform runs on Ceph, spans multiple data centers, and holds double-digit petabytes of customer data. It is growing fast. We are looking for a staff-level engineer who knows Ceph, Linux and the network underneath it well enough to keep it healthy as it scales.

We follow a "you build it, you run it" model. You will deploy, operate and improve the platform with the Network, SRE, Data Center and infrastructure support teams. A separate development team works on the product, and you will work closely with them.

Your tasks

• Own the reliability, performance and capacity of our production Ceph clusters across locations
• Solid understanding of server hardware (disks, controllers, NICs) and how it affects storage performance, so you can diagnose hardware-related issues remotely
• Diagnose the hardest issues across the full stack, from disk and server through the Linux network stack to the Ceph service, and lead incident response and postmortems
• Automate deployments, upgrades and routine operations (Ansible) so they need less manual work
• Build monitoring and observability that catch problems before customers do
• Plan capacity and growth with the Data Center and Network teams
• Take part in the on-call rotation
• Follow Ceph releases and the community, and bring useful practices back to the team

Your profile

• 5+ years as an SRE, Linux or storage engineer, with proven experience running Ceph in production (the more petabytes the better; 20 PB+ clusters are ideal)
• Strong knowledge of Linux and its network stack, plus good networking fundamentals
• Solid understanding of server hardware (disks, controllers, NICs) and how it affects storage performance
• Experience with object, block and file storage concepts
• Automation experience, ideally Ansible, and scripting in Python or Bash (you don't need to be a software engineer)
• Monitoring and observability experience (e.g., Prometheus, Grafana)
• Calm, structured troubleshooting when things break, and clear communication in English (German is a plus)
• Willingness to undergo extended security vetting (SÜ2)

Benefits

• Hybrid working model.
• Flexible working hours through trust-based working hours.
• At some locations a subsidized canteen and various free drinks.
• Modern office space with very good transport connections.
• Various employee discounts for activities and products.
• Employee events such as summer and winter parties, as well as workshops.
• Numerous training and development opportunities.
• Various health offers, such as sports and health courses.
