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.

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
