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.
