Senior Systems Engineer — AI Code Metrics Daemon

Working at Atlassian
Atlassians can choose where they work - whether in an office, from home, or a combination of the two. That way, Atlassians have more control over supporting their family, personal goals, and other priorities. We can hire people in any country where we have a legal entity.
We're building the observability layer for AI-assisted software development, measuring how much of an engineering org's code is actually written by AI coding agents, and attributing every line back to the work that produced it. You'll own major parts of a cross-platform endpoint agent end-to-end: architecture, implementation, and real-world deployment onto developer machines.
What You'll Do

• Build the core systems that detect and attribute AI-generated code at the line level across real Git workflows (rebases, cherry-picks, resets, and all)
• Design reliable pipelines for capturing, classifying, storing, and shipping developer + agent activity from the endpoint
• Work directly with Git internals (reflog, commit identity across history rewrites, blob-level attribution) to collect data without interrupting developers
• Build and maintain integrations with coding agents (Cursor, Claude Code, Copilot, Codex, Gemini CLI, and more) via editor/CLI hooks
• Own cross-platform behavior across macOS, Linux, and Windows

What We're Looking For

• Strong systems engineer - backend, OS internals, endpoint/agent software, or developer infrastructure
• We use Go, but it's fine if that's not your background (what matters is comfort with concurrent, long-running, low-level software)
• Experience building production systems that must be fast, reliable, and invisible to the user
• High-agency, high-responsibility individuals with strong product intuition (you care how developers experience what you build)
• Excited about developer tools and using data to understand how engineers actually work with AI coding agents
• Bonus: Git internals, developer tools / dev infra, endpoint or monitoring agents (EDR, sync clients, telemetry agents), SQLite or embedded storage, or cross-platform native development
