Principal Engineer, Backend Engineering

Atlassian's internal AI usage is growing rapidly across engineering, driven by adoption of tools like Codex, Cursor, Claude Code, and Rovo CLI. This growth is a signal of value, and we need a Principal Engineer to build the infrastructure that makes it sustainable.

You will own the technical vision and architecture for the DevInfra AI Front Proxy, a cloud-hosted service that sits at the developer-workflow boundary and governs every internal model call against cost, trust, context, and attribution constraints. The proxy spans three integration surfaces: managed local configuration pushed via MDM, the cloud proxy service itself, and a browser extension for web AI interfaces. It is the single layer through which all internal AI traffic flows for cost enforcement, security policy integration, model routing, semantic caching, and telemetry.

This is a high-impact, high-ambiguity role. You will partner with teams across developer infrastructure, AI platform, security and compliance, and developer tooling to define and ship the platform that makes exponential AI usage growth safe, measurable, and cost-efficient at Atlassian scale.
