Job description

Canonical is a leading provider of open source software and operating systems to the global enterprise and technology markets. Our platform, Ubuntu, is very widely used in breakthrough enterprise initiatives such as public cloud, data science, AI, engineering innovation and IoT. Our customers include the world's leading public cloud and silicon providers, and industry leaders in many sectors. The company is a pioneer of global distributed collaboration, with 1100+ colleagues in 75+ countries and very few office based roles. Teams meet two to four times yearly in person, in interesting locations around the world, to align on strategy and execution. The company is founder led, profitable and growing.

Canonical is building a new generation of Ubuntu‑based container images to simplify open‑source application deployment across the world. These container images will be free to use with long‑term security commitments, and engineered for performance, security and usability. As with Ubuntu, we will work in the open and welcome community participation.

In this role, you’ll be developing the tools and technology for building and maintaining this new generation of container images. You’ll be working with multiple teams, both inside and outside Canonical, to ensure we deliver container images with the highest quality whilst maintaining a seamless Ubuntu user experience. You will also be highly involved in the implementation and maintenance of the Continuous Integration and Continuous Delivery automation around these container images, for which you are expected to demonstrate deep insights into container‑based DevOps.

You will be contributing to fast‑moving products like Rocks (OCI images) and Chisel, and thus have the chance to help steer and consolidate this new team. You’ll gain experience with numerous container technologies and participate in exciting and exploratory tasks, where your feedback will be critical for the decision‑making process. As an engineer, your seniority will be based on your software development background and ability to lead junior team members.

Come build a rewarding, meaningful career working with the best and brightest people in technology at Canonical. This is an exciting opportunity for experienced software engineers looking for a place to leave their mark, who are passionate about shaping an open source product with the highest quality, with and for the community!
