Senior Machine Learning Engineer

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. Interviews and onboarding are conducted virtually, a part of being a distributed-first company.

About the team

Jira is Atlassian's flagship work‑tracking product and one of the most important systems of work in the world. Working on Jira Experience as an ML engineer means building the intelligence layer on top of that system of work. You get to design AI that orchestrates work between humans and machines: models that infer intent from messy, unstructured input; recommend the next best action across fragmented tools; and personalize workflows to the unique patterns of each team.

The problem space is both broad and deep spanning large‑scale retrieval and ranking, representation learning on the teamwork graph, multi‑modal understanding across text and video, and human‑in‑the‑loop systems embedded directly in product. It's a rare opportunity where solving hard ML problems doesn't just move an internal metric; it directly reshapes how the world's teams coordinate, collaborate, and ship work using Jira.
