Technology Focus

This is a general selection process for software engineers focused on virtualisation and container technology – from the kernel through userspace. Apply if you are an exceptional Go, Rust or C/C++ engineer and want to work on next‐generation open source VMM or container technology, or related open source networking and storage. Container, virtualisation and cloud infrastructure are essential for modern software deployments.

We invest in open source related to application isolation, workload orchestration, system or OCI containers, micro‐service architecture, or cloud infrastructure. LXD – a modern system container and virtual machine manager used on Ubuntu, ChromeOS and other Linux platforms, covering low‐level kernel work, filesystems, VMMs, networking,



and higher‐level REST API and CLI. OpenStack (Charmed OpenStack, OVN/OVS, Ceph) – delivering cloud platform technologies to large‐scale computing environments.

These teams hire system‐level C/C++, Go, Rust and Python developers to work on security‐critical, performance‐critical and mission‐critical code, focused on software delivery, containers, security, sandboxing, application orchestration and management. We have remote container and virt engineering roles in every time zone. Conduct security analysis and reviews to ensure defence in depth.

Collaborate proactively with a distributed team. Write high‐quality code to create new features. Debug issues and produce high‐quality code to fix them. Review code produced by other engineers. Undergraduate degree in Computer Science or STEM, or a compelling narrative about an alternative path.

Experience working on open‐source virtualisation or container technology. Professional written and spoken English. Performance engineering and security experience. Distributed work environment with twice‐yearly team sprints in person. Whatever your identity, we will give your application fair consideration.
