IONOS Cloud runs on highly available, redundant block storage that must be provisioned quickly, reliably and at scale. You own the software behind it and build on the Linux storage stack instead of reinventing it. Your focus is provisioning.
Tasks
- Maintain and improve our existing block storage provisioning
- Design and develop the next generation of our storage provisioning
- Add monitoring and alerting for the provisioning workflow to detect failures early
- Make provisioning robust against failures and safe to retry
- Design and implement provisioning that keeps storage highly available and redundant, including failover
- Analyze and resolve complex issues across the storage stack, from the Linux kernel up to the provisioning layer
- Migrate from legacy components step by step, without breaking existing users
Qualifications
- Expert Go skills and several years of professional development experience
- Deep knowledge of Linux, including the kernel, block storage, software RAID (MD), LVM and network block devices (NBD, RNBD)
- Experience with VMs (libvirt, QEMU, cloud-init), building VM images and developing Kubernetes Operators
- Working knowledge of C, enough to read and debug low-level code
- Fluency with Git, Docker, shell and CI/CD, including GitOps workflows (for example ArgoCD)
- Experience with observability tools (Prometheus, Grafana) to monitor provisioning and troubleshoot issues
- Experience building highly available, redundant systems, including replication, failover and distributed-systems fundamentals (idempotency, retries, consistency, failure handling)
- Affinity to cloud environments and to automating infrastructure provisioning
- Daily use of AI coding assistants (for example Claude) in your development work
- Strong analytical and problem-solving skills and a structured, independent way of working in a team
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.
