Virtualization Software Engineer

Who we’re looking for

• 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 namespaces, bridging
• Comfortable designing and shipping long-lived services (APIs, lifecycle, error handling, observability)
• Excellent problem-solving, analytical, and debugging skills
• Strong communication and documentation abilities
• Fluency with modern AI-assisted development tools
• Fluent in English

What you’ll do

• 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
