Role Summary Ubiquiti's Prague office is looking for a Virtualization Software Engineer to build a new internal platform for managing virtual machines at scale. You'll design and implement a greenfield service on top of libvirt/QEMU that orchestrates VM lifecycle and virtual network topologies, exposed via an API to other internal systems. The project stack: C++ (greenfield project — not a hard requirement; e. g. Go or Rust are fine if you make the case) libvirt / QEMU / KVM Linux (networking, bridging, virtio) Responsibilities: Design and implement a service that manages VM lifecycle (create, start, stop, snapshot, destroy) on top of libvirt Expose a clean API consumed by other internal tools and services Model and provision multi-node virtual network topologies (bridges, VLANs, virtio-net) Own the component end-to-end: architecture, implementation, tests, observability, and documentation Collaborate with adjacent teams on integration and end-to-end scenarios Requirements: 5+ years of professional software engineering experience Proficiency in C/C++ (or Go/Rust), with familiarity in Linux-based networking stacks Hands-on experience writing software against the libvirt API, QMP, or directly against QEMU/KVM — not just operating VMs through a GUI Solid understanding of Linux virtualization internals: KVM, virtio, vhost, network namespa
