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.

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.

Location: we have remote opportunities for Senior Engineers in every time zone.
