System Software Engineer - Ubuntu Networking

San Antonio, TX, United States

Our growing investment in Ubuntu now enables us to hire a group of outstanding systems software engineers to focus on the connectivity of Ubuntu in a wide range of circumstances, from cloud to server to desktop and IoT. We would like to strengthen the tooling, services, documentation, robustness, security and clarity of Linux network abstractions to provide fast, reliable and secure connections for Ubuntu.

The network stack is one of the most critical aspects of any operating system where stability, reliability and uptime are paramount. Its ease of use and reliability contribute to Ubuntu's success from IoT, Desktop, Server to the Cloud. We are expanding our Foundations team to focus our efforts on this essential function and are looking for people passionate about lower level technologies involved in an operating system's network stack. Applicants will be comfortable discussing bridges, bonds, routing, DNS resolution and other technologies used to interconnect modern operating systems. We'll work with a very wide range of upstream components and communities covering a wide range of connectivity tech. We might touch the kernel, iwd, networkmanager, wpa_supplicant, bluetooth stacks, conman, mobile data stacks, ethernet, infiniband, network virtualisation capabilities, VPNs and offload to smartnics. We model Ubuntu connectivity with Netplan and will continue to drive this forward as the easiest and most effective central tool to enable connectivity everywhere.

The Ubuntu Foundations Team delivers and maintains the core of the Ubuntu system, the base for the entire Ubuntu family of products and services. Ubuntu strives to deliver the latest and best free software components, in an easy to use and highly reliable form. We build on the technical excellence of Debian and bring additional focus and shape to the solutions we offer industry.

As a Linux System Engineer, you will maintain and integrate core components involved in the network stack of the Ubuntu Distribution. You will be discussing design with other team members, upstream projects, mentor less senior engineers and participate in code reviews and design reviews. You will also be working with other teams to ensure architecture decisions improve the overall performance and experience of Ubuntu.

Location: The Foundations team is based in EMEA and Americas time zones, from UTC+4 to UTC-8.
