About this role.
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.

We are hiring a Software Engineer for Ceph & Distributed Storage. As part of Cloud Engineering, you’ll be building modelling software to drive systems such as OpenStack, Ceph, and Kubernetes with a focus on distributed storage and Ceph. You’ll be engineering solutions to scale in production, working with our field teams to ensure we’re meeting the needs of customers looking to adopt cutting-edge technology.
Applicants should be passionate about the future of the software defined datacenter, distributed systems, and open source. Canonical is a globally distributed team of engineers who share that passion, and you will need to work well in that context.

Sample interview questions
I would first establish the scope through client latency, OSD latency, network, disk, and monitor metrics, then correlate the timing with recovery, rebalancing, backfill, workload changes, and hardware events. I would inspect Ceph health details and logs, validate CRUSH placement and pool settings, and isolate whether the bottleneck is network, storage media, CPU, or an uneven OSD workload before proposing a low-risk remediation.
I would separate API, domain, and infrastructure concerns, define idempotent operations, and use explicit state transitions for lifecycle actions. The service would include retries with backoff, timeouts, structured logging, metrics, input validation, and clear error handling. I would also create unit and integration tests around failure scenarios such as unavailable nodes, partial completion, and conflicting requests.
The operator should reconcile desired and observed state safely and idempotently, expose meaningful status conditions, and avoid destructive actions without safeguards. It should manage upgrades, configuration changes, secret handling, health checks, resource limits, and recovery from failed reconciliations. Documentation and observability are also essential so operators can understand and safely operate the system.
I start by improving observability and collecting evidence from the affected environment, including logs, traces, metrics, configuration, versions, and event timelines. I form testable hypotheses, narrow variables through comparison with healthy systems, and build a minimal reproduction or simulation where possible. I communicate findings and uncertainty clearly, then validate the fix with targeted tests and production-safe rollout steps.
I would make progress visible through concise written updates, well-scoped issues, design proposals, and reviewable pull requests. I would document decisions and trade-offs asynchronously, seek early feedback on ambiguous work, and remain responsive across time zones without relying on meetings for every decision. For open-source contributions, I would follow project conventions and engage constructively with maintainers and users.
