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.\nWe 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.\nYou 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.\nAt 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.\nLocation: we have network software engineering roles in APAC (Top-of-Rack switches) and Americas (SmartNIC/DPU) time zones.\nWhat your day will look like\nWork with the most advanced operating systems and network application technologies available\nParticipate upstream and deliver the Ubuntu SoNIC stack\nCollaborate with public clouds and network silicon providers\nDesign and implement the best software-defined networking experience for the data center\nWrite high-quality, well-designed, fast, secure and well-documented software\nDebug issues and produce high-quality fixes\nCollaborate proactively with a globally distributed organization\nContribute to technical documentation to make it the best of its kind\nDisplay technical leadership internally, towards our partners, and in the open source communities\nInfluence open-source projects and communities\nWork from home, with global travel twice a year for company events of up to two weeks duration\nWhat we are looking for in you\nAn exceptional academic track record\nUndergraduate degree in Computer Science or STEM, or a compelling narrative about your alternative path\nDrive and a track record of going above-and-beyond expectations\nKnowledge of networking: architecture, design, and protocols\nUnderstanding of Linux networking, from kernel to user space\nFluency in C/C++ and at least one of Rust, Python or Golang\nProfessional written and spoken English \nExperience with Linux\nExcellent interpersonal skills, curiosity, flexibility, and accountability \nPassion, thoughtfulness, and self-motivation \nExcellent communication and presentation skills \nResult-oriented, with a personal drive to meet commitments \nAbility to travel twice a year, for company events up to two weeks each\nAdditional skills that you might also bring\nFamiliarity with existing open source networking technologies: SONIC / SAI, kernel (e.g. eBPF, AF_XDP), DPDK, Switchdev, OVN, Open vSwitch.\nFamiliarity with data path hardware acceleration protocols and interfaces, such as RDMA, RoCE, iWARP, NVMe, SR-IOV\nComputer architecture knowledge of x86, ARM, and RISC-V\nExperience in complex IP network engineering and implementation\nExperience with virtualization technologies, e.g., QEMU, KVM, etc.\nPrevious contribution to open source projects and community involvement\nPerformance engineering and security experience\nWhat we offer you\nWe consider geographical location, experience, and performance in shaping compensation worldwide.
