Senior Site Reliability Engineer

Join to apply for the Senior Site Reliability Engineer role at Canonical
.

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, and industry leaders in many sectors. The company is a pioneer of global distributed collaboration with over 1,200 colleagues in more than 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 Engineer to lead next‑generation operations at scale, using pure Python infra‑as‑code from bare metal to containers and applications. The goal is to perfect enterprise infrastructure Dev Ops.

We run hundreds of private cloud, Kubernetes, and application clusters for customers across physical and public cloud estates, raising the bar on automation by embracing a universal operator pattern and model‑driven operations.

To succeed in this role, you need to believe in automation as a pure software engineering problem, not a hack‑it‑till‑it‑works‑for‑me problem. You should be interested in the scientific approach to operations at scale, driven by metrics and code, and you must be able to learn the entire stack – from bare metal networking and kernel up to serverless and open source applications.

Location:

Globally remote role.

As a cloud operations engineer, you will bring Python software‑engineering skills and rigour to the operations domain, practicing Dev Sec Ops  from bare metal to application. You will architect and run Open Stack, Kubernetes and software‑defined storage, and enable Dev Sec Ops  for applications running on that infrastructure.

You will work in a high‑pressure operations environment with mission‑critical services for global brand‑name customers, gaining experience across a broad range of cloud technologies and staying current with the latest capabilities in open source infrastructure.

• Degree in Software Engineering or Computer Science

• Distributed work environment with twice‑yearly team sprints in person
