Open Source Networking Software Engineer

Open Source Networking Software Engineer - ToR Switch / SmartNIC / DPUSoftware 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.Location: we have network software engineering roles in APAC (Top-of-Rack switches) and Americas (SmartNIC/DPU) time zones.What your day will look likeWork with the most advanced operating systems and network application technologies availableParticipate upstream and deliver the Ubuntu SoNIC stackCollaborate with public clouds and network silicon providersDesign and implement the best software-defined networking experience for the data centerWrite high-quality, well-designed, fast, secure and well-documented softwareDebug issues and produce high-quality fixesCollaborate proactively with a globally distributed organizationContribute to technical documentation to make it the best of its kindDisplay technical leadership internally, towards our partners, and in the open source communitiesInfluence open-source projects and communitiesWork from home, with global travel twice a year for company events of up to two weeks durationWhat we are looking for in youAn exceptional academic track recordUndergraduate degree in Computer Science or STEM, or a compelling narrative about your alternative pathDrive and a track record of going above-and-beyond expectationsKnowledge of networking: architecture, design, and protocolsUnderstanding of Linux networking, from kernel to user spaceFluency in C/C++ and at least one of Rust, Python or GolangProfessional written and spoken EnglishExperience with LinuxExcellent interpersonal skills, curiosity, flexibility, and accountabilityPassion, thoughtfulness, and self-motivationExcellent communication and presentation skillsResult-oriented, with a personal drive to meet commitmentsAbility to travel twice a year, for company events up to two weeks eachAdditional Skills That You Might Also BringFamiliarity with existing open source networking technologies: SONIC / SAI, kernel (e.g. eBPF, AF_XDP), DPDK, Switchdev, OVN, Open vSwitch.Familiarity with data path hardware acceleration protocols and interfaces, such as RDMA, RoCE, iWARP, NVMe, SR-IOVComputer architecture knowledge of x86, ARM, and RISC-VExperience in complex IP network engineering and implementationExperience with virtualization technologies, e.g., QEMU, KVM, etc.Previous contribution to open source projects and community involvementPerformance engineering and security experienceWhat we offer youDistributed work environment with twice-yearly team sprints in personPersonal learning and development budget of USD 2,000 per yearAnnual compensation reviewRecognition rewardsAnnual holiday leaveMaternity and paternity leaveEmployee Assistance ProgrammeOpportunity to travel to new locations to meet colleaguesPriority Pass, and travel upgrades for long haul company eventsAbout CanonicalCanonical is a pioneering tech firm at the forefront of the global move to open source.As the company that publishes Ubuntu, one of the most important open source projects and the platform for AI, IoT and the cloud, we are changing the world every day.We recruit on a global basis and set a very high standard for people joining the company.Canonical is an equal opportunity employer.We are proud to foster a workplace free from discrimination.Diversity of experience, perspectives, and background create a better work environment and better products.Whatever your identity, we will give your application fair consideration.#J-*****-Ljbffr
