This fast-paced engineering role focuses on Linux-based software-defined infrastructure and applications, covering all layers of the stack, including bare metal, virtualization (KVM) and containerization (Docker, LXC/LXD), storage (Ceph and Linux filesystems), networking (OVS, OVN and Core networking), up to OpenStack and Kubernetes, and the open source applications running on top of them. Resolving complex customer problems related to Ubuntu, OpenStack, or Kubernetes and other open source software, maintaining a close working relationship with Canonical's field, support and product engineering teams and participating in upstream communities are core to the job.
