About the Job: Junior Software Engineer at Canonical (Ubuntu Engineering)

Canonical is a global leader in open source software and operating systems, renowned for Ubuntu – a platform widely adopted in breakthrough enterprise initiatives such as public cloud, data science, AI, engineering innovation, and IoT. Our diverse customer base includes the world’s leading public cloud and silicon providers, alongside industry leaders across various sectors.

As a pioneer of global distributed collaboration, Canonical thrives with over 1200 colleagues spanning 75+ countries, with very few office-based roles. Teams regularly convene two to four times annually in intriguing international locations to align on strategy and execution. The company is founder-led, profitable, and experiencing strong growth.

We are seeking junior engineers to join our Ubuntu Engineering organization. We’re looking for individuals who possess a deep commitment to quality, performance, and resilience in software. Ideal candidates will be equally comfortable designing and engineering new software as they are packaging, integrating, testing, and shipping the vast catalog of open source software available in the Ubuntu repositories.

Our engineers are at the forefront of integrating the freshest open source software, providing robust upgrade paths, and engineering the future of Ubuntu. Ubuntu is not merely the world’s most deployed open source operating system; it’s a dynamic platform empowering innovation for millions of users globally, from students and hobbyists to high-performance engineering and creative teams in corporate and academic environments.

Key Ubuntu Engineering Teams:

You could be working with one of these pivotal teams that ship Ubuntu:

  • Foundations: Dedicated to maintaining foundational software, including architectures, package managers, compilers, toolchains, bootloaders, filesystems, and core utilities.
  • Server: Leading the design, evolution, and future direction of our Ubuntu Server distribution.
  • Desktop: Driving Ubuntu Desktop, including the future immutable desktop (Ubuntu Core Desktop), WSL, gaming technology, and a suite of modern desktop applications crafted with Flutter.
  • Debcrafters: A newly formed team responsible for the forward movement, maintenance, and overall health of the Ubuntu archive—one of the most abundant repositories of open source software available today.

What You Could Work On:

Bring your existing expertise and develop new skills by contributing to one of the most prolific pieces of open source software. As an engineer working on Ubuntu, your responsibilities could fall into any or all of the following categories:

  • Development: Design, build, and ship new foundational systems software and applications using languages like Rust, Go, Flutter, and Python.
  • Architecture: Engineer the seamless integration of open source components, from boot firmware to cloud application deployment.
  • Packaging: A combination of Debian and Snap packaging to effectively ship software within the distribution.
  • Automation: Build and maintain the critical machinery responsible for building, testing, and shipping Ubuntu.
  • Distro Engineering: The ongoing maintenance and evolution of a leading Linux distribution and its expansive repositories.

If you possess skills in these areas, or other skills you believe can contribute to Ubuntu, and you are eager to build your career in open source, this role is for you. Our junior career path is designed to support both new graduates and early-career engineers.

At Canonical, you will have ample opportunities to engage with and contribute to the broader open source community. We are looking for individuals who can help foster a thriving community and contribute with enthusiasm and precision across a broad range of technologies.

  • Packaging, integrating, testing, and uploading open source software to the Ubuntu repositories.
  • Debugging complex issues, then designing and delivering robust solutions.
  • Authoring and improving technical and community documentation.
  • Contributing to upstream and neighboring open source projects.
  • Collaborating effectively as part of a globally distributed team.
  • Continuously learning and progressing their technical and professional skills.
