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.

This is a general track for Senior+ (Senior/Staff/Principal) Engineers in any team at Canonical. After the first round of interviews we will establish which teams might be an excellent fit, and progress your application with them.

At Canonical a Senior+ Engineer is not only an outstanding software architect and coder, they also demonstrate the leadership qualities needed to rally a team or department to ship outstanding products. A Senior+ Engineer partners with other Engineering leaders (Managers, Directors, VPs) to take joint responsibility for outcomes at team, department and company level. We hire based on academic results and proven execution, and we select those with a passion for open-source software, innovation, and cutting-edge technology. In this role, you will make a significant contribution in Canonical's portfolio through high-quality code, technical leadership, team motivation and direction, exceptional design, and crisp documentation.

As a Senior+ Engineer you'll drive the architecture, design and evolution of high-impact open source software. Our teams work at every level of the stack. From the kernel and system software at the core of Ubuntu through to major language runtimes and the bleeding-edge of cloud automation and distributed systems, you'll have the opportunity to work on complex but highly rewarding projects. Our teams also build the services which deliver Ubuntu to the world, on cloud, devices, servers and PCs.

Additionally, this role will give you the opportunity to engage with the broader open-source community. We're looking for individuals who can help build a thriving community, contribute to a broad range of technologies, and ensure seamless software operations at scale.
