AI Summary

The role, at a glance.

Canonical is seeking a Go software engineer to develop and support Juju, an open-source platform for automating distributed software and infrastructure operations. The role focuses on designing concurrent, distributed systems that operate across public and private clouds, Kubernetes, and bare-metal environments. The engineer will collaborate asynchronously with a distributed global team, debug production and upstream issues, and contribute publicly to open-source communities. Strong Go development experience, written English communication, and comfort with Linux, cloud, networking, and container technologies are central to success. The role is home-based within EMEA and includes periodic travel for team and company events.

Sample interview questions
How would you structure a Go service that must safely process many concurrent operations?

I would define clear ownership of shared state, favor message passing or well-scoped synchronization, use contexts for cancellation and deadlines, and protect critical sections with appropriate primitives such as mutexes or channels. I would also add race detection, load tests, metrics, and structured logging to validate correctness and behavior under contention.

Describe how you would investigate an intermittent failure in a distributed system.

I would first establish the failure pattern, affected versions, and environmental conditions. Then I would correlate logs, traces, metrics, and relevant state across components, form and test hypotheses, and create a minimal reproduction where possible. After fixing the cause, I would add regression coverage and observability that makes recurrence easier to detect.

What considerations matter when integrating a system with Kubernetes or another container platform?

I would consider desired-state reconciliation, idempotent operations, authentication and authorization, resource limits, networking, persistent storage, upgrade paths, and failure recovery. I would use the platform APIs carefully, handle eventual consistency, and ensure the integration produces actionable status and error information.

How do you contribute effectively to an open-source project with distributed maintainers?

I begin by understanding project conventions and existing discussions, then propose focused changes with clear rationale and tests. I keep pull requests small, respond constructively to review feedback, document trade-offs, and communicate progress transparently so maintainers can evaluate and integrate the work efficiently.

How would you decide between SQL and NoSQL storage for an infrastructure automation feature?

I would start with the access patterns, consistency needs, data relationships, scale, operational requirements, and query requirements. SQL is usually preferable for transactional workflows and rich relational queries, while a NoSQL option can fit flexible schemas or high-scale key-based access. The decision should include backup, migration, observability, and operational complexity.
