Dear Hiring Team,

I am writing to express my strong interest in the Senior Site Reliability Engineer position at Canonical. With a degree in Computer Science and extensive experience in Python software engineering and Linux operations, I am confident in my ability to contribute to your mission of perfecting enterprise infrastructure devops. My background includes deploying and managing OpenStack and Kubernetes clusters at scale, and I thrive in high-pressure environments that demand automation and reliability.

Canonical's pioneering work in open source and distributed collaboration aligns perfectly with my values. I am excited by the opportunity to work on cutting-edge infrastructure and to continuously learn and improve. Thank you for considering my application.

Sincerely,
[Your Name]

### Sample Interview Questions

Describe your experience with Python in the context of infrastructure automation. How have you used Python to manage systems at scale?I have used Python extensively to write automation scripts for provisioning, configuration management, and monitoring. For example, I developed a Python-based tool to automate the deployment of Kubernetes clusters across multiple cloud providers, which reduced setup time by 80% and ensured consistency.Can you walk us through a time you handled a major incident in a production environment? What steps did you take?In a previous role, a critical database cluster experienced a sudden performance degradation. I first triaged by checking monitoring dashboards and logs, identified a query deadlock, then coordinated with the development team to roll back a recent code change. I also implemented automated alerting and a runbook to prevent recurrence.How do you approach designing a resilient system? Give an example of a design you implemented.I follow the principle of designing for failure. For a microservices architecture, I implemented circuit breakers, retries with exponential backoff, and distributed tracing. I also set up multi-region deployment with active-passive failover, which was tested regularly through chaos engineering experiments.Explain the difference between reliability and availability. How do you measure and improve both?Availability measures uptime (e.g., 99.9% availability), while reliability includes correctness and performance under load. I use Service Level Indicators (SLIs) like latency and error rate, and define Service Level Objectives (SLOs). To improve, I focus on error budgets, blameless postmortems, and automated remediation.Why are you interested in joining Canonical specifically, and how do you feel about the distributed work model with twice-yearly travel?I admire Canonical's leadership in open source and its global remote-first culture. The opportunity to work with a diverse team and travel to sprints is appealing. I believe remote work fosters autonomy and deep focus, while in-person sprints build strong relationships, which I've experienced successfully in past remote roles.  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 Senior Site Reliability Engineer

Next-gen operations at scale, with pure Python infra-as-code, from bare metal to containers and applications. Our goal is to perfect enterprise infrastructure devops.

We run hundreds of private cloud, Kubernetes, and application clusters for customers across physical and public cloud estate, and we are raising the bar on what’s possible with 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 need to be interested in the scientific approach to operations at scale, driven by metrics and code, and you need to be able to learn the entire stack, from bare metal networking and kernel up to serverless and open source applications.

Location: Globally remote role

## The role entails

Our cloud operations engineers bring Python software-engineering skills and rigour to the operations domain. We practise devsecops from bare metal to application. We architect and run OpenStack, Kubernetes and software defined storage, and we enable devsecops for applications running on that infrastructure too.

To become a member of this team, you need to be a software engineer fluent in Python, you need a genuine interest in the full open source infrastructure stack from metal to containers, and you need the ability to work in a high pressure operations environment with mission-critical services for global brand name customers.

We evolve our offerings as the state of the art improves, so you get to stay current with the latest capabilities in open source infrastructure. We drive upgrades to keep our customers on the latest, best solutions.

## What we are looking for in you

* Degree in Software Engineering or Computer Science
* Experience with Linux and familiarity with Linux networking and storage
* Python software development expertise
* Operational experience
* Excellent interpersonal skills, curiosity, flexibility, and accountability
* Ability to travel internationally twice a year, for company events up to two weeks long

## Nice-to-have skills

* Experience with OpenStack or Kubernetes deployment or operations
* Familiarity with public or private cloud management

## What we offer colleagues

We consider geographical location, experience, and performance in shaping compensation worldwide. We revisit compensation annually (and more often for graduates and associates) to ensure we recognise outstanding performance. In addition to base pay, we offer a performance-driven annual bonus or commission. We provide all team members with additional benefits, which reflect our values and ideals. We balance our programs to meet local needs and ensure fairness globally.

* Distributed work environment with twice-yearly team sprints in person
* Personal learning and development budget of USD 2,000 per year
* Annual compensation review
* Recognition rewards
* Annual holiday leave
* Maternity and paternity leave
* Employee Assistance Programme
* Opportunity to travel to new locations to meet colleagues
