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 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, as well as industry leaders in many sectors. The company is a pioneer of global distributed collaboration, with 1,200+ 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.

We are hiring a Senior Site Reliability / Git Ops Engineer for our Information Systems (IS) team. This role offers an opportunity for an automation‑first senior technologist with a passion for Linux to build a career with Canonical and drive success for those leveraging Ubuntu and open source products. If you have experience in IT operations automation, Infrastructure as Code, and a passion for technology, you will enjoy working with some of the best people in the industry at Canonical.

The IS team at Canonical supports and maintains all of Canonical’s IT production services, running services used by over 60 million Ubuntu users.

As a Senior SRE & Git Ops engineer, you’ll drive operations automation to the next level, both in our private clouds and public clouds. You will utilize open source infrastructure as code software, CI/CD pipelines, and Canonical’s leading products for software operation automation. In addition, you will improve Canonical products and open‑source technologies by providing critical feedback to developers, submitting bugs, writing pull requests, and collaborating on design and implementations with other teams.

You will be part of a global team of SREs that support each other to provide the best possible services to the company, Canonical’s customers, and the Ubuntu community.

• Provide assistance and work with globally distributed engineering, operations, and support peers.
• Earn uninterrupted development time to focus on larger projects and automation of manual tasks.
• Share experience, know‑how, and best practices with other team members in design sessions, mentorship, and “doing work together.”
