Software Engineer - Python - Ubuntu Pro client - graduate level

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 1200+ 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 Software Engineer to develop, test and release improvements to the Ubuntu Pro client.

Ubuntu Pro is a suite of specialist services provided by Canonical. Whether for enterprise customers deploying systems at scale or users who want security patching for their personal Ubuntu LTS at home, the Ubuntu Pro Client is the command‑line tool that manages all these services.

The quality and stability of the Ubuntu Pro Client is critically important, since it comes pre‑installed on every Ubuntu system. You’ll work with the Ubuntu Server team, alongside major cloud partners and multiple Canonical product teams to develop, test and release improvements to the Pro client. You will also be a voice in communication with our users, ensuring their needs are met.

This role requires quality‑oriented software engineering in Python and a focus on software interoperability over a vast range of target releases and environments. Excellent Python skills are a key requirement, with previous contributions to open source Python projects being an advantage. The Pro client often interacts with the Ubuntu package management; therefore, experience in configuring apt, and knowledge of deb packaging and general system administration is advantageous in this role.

Applicants should be passionate about the Ubuntu project and its values and about building tools that are used by millions of people around the world. A personal interest and emphasis on quality, thinking of edge cases, ease of use, documentation, and careful community coordination is important. The Pro client is used at all ranges, from mission‑critical environments to hobbyist Ubuntu users; applicants should be ready to work with the whole spectrum of end users and help guide engineering best practices with all of them in mind.
