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 like Work with the most advanced operating systems and network application technologies available Participate upstream and deliver the Ubuntu SoNIC stack Collaborate with public clouds and network silicon providers Design and implement the best software-defined networking experience for the data center Write high-quality, well-designed, fast, secure and well-documented software Debug issues and produce high-quality fixes Collaborate proactively with a globally distributed organization Contribute to technical documentation to make it the best of its kind Display technical leadership internally, towards our partners, and in the open source communities Influence open-source projects and communities Work from home, with global travel twice a year for company events of up to two weeks duration What we are looking for in you An exceptional academic track record Undergraduate degree in Computer Science or STEM, or a compelling narrative about your alternative path Drive and a track record of going above-and-beyond expectations Knowledge of networking: architecture, design, and protocols Understanding of Linux networking, from kernel to user space Fluency in C/C++ and at least one of Rust, Python or Golang Professional written and spoken English Experience with Linux Excellent interpersonal skills, curiosity, flexibility, and accountability Passion, thoughtfulness, and self-motivation Excellent communication and presentation skills Result-oriented, with a personal drive to meet commitments Ability to travel twice a year, for company events up to two weeks each Additional Skills That You Might Also Bring Familiarity with existing open source networking technologies: SONIC / SAI, kernel (e.g. eBPF, AF_XDP), DPDK, Switchdev, OVN, Open vSwitch.
