About the role
About the Role
Software has moved to play a central role in network technology. From outstanding routing implementations like Bird and FRR to overlay networking technology such as OVN/OVS and Cilium, from kernel with SwitchDev to userspace with DPDK, from P4 to OpenFlow, the relationship between network innovation and software continues to deepen. We are building teams to bring the very best open source networking software to market in a well integrated and opinionated stack that brings the latest hyperscaler innovation to end users and enterprise customers.
We work with networking silicon providers to optimize Ubuntu and related applications for their ASICs, boards and appliances. We aim to provide a complete open source stack for data center networking, from bare metal through virtualization, container and serverless, and also to address IoT networking systematically.
You will have a good chance of success if you are an outstanding software engineer, passionate about networking, with a special interest in the interface of hardware ASICs for acceleration and software for innovation and control. We value experience in open switch initiatives such as SoNIC and DENT, and upstream experience with components such as routing, kernel networking, eBPF, DNS, firewalls and load balancers. Our selection process is rigorous and requires work from the candidate as six to eight interviews over a period of months. We look for excellent academic results and a commitment to quality, resilience, documentation, security and performance in your work.
At Canonical you will have the opportunity to engage with the broader open-source community and industry leading partners in developing future-proof networking solutions. We're looking for individuals who can help build a thriving community, contribute to a broad range of technologies, and contribute to the deployment of Ubuntu, Ubuntu Core, Private Clouds, MAAS and Kubernetes across a broad range of devices and use cases.
