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.

Dev Infra builds the tools, platforms, and infrastructure that every engineer at Atlassian uses to ship. We are hiring a Senior Principal Engineer for our AI Foundations team, the group responsible for making AI work well across our engineering: how we measure it, the context we feed it, and the compute it runs on.

The reach of this work is unusual. Because Dev Infra builds and stress tests the same class of developer tools Atlassian sells, what you build shapes both how Atlassian ships software and what Atlassian ships to millions of developers.

In this role, you will:

• Set the technical vision for how Atlassian enables and builds AI across the software development lifecycle, and turn it into infrastructure teams adopt.
• Stay hands on. Prototype the hardest parts yourself, write code, and set the engineering bar others build to. At this level you lead by doing.
• Build the foundational systems that make AI effective for every engineer, including how we measure whether AI works, give it the right context, and run it reliably and affordably at scale.
• Give engineers and leaders real signal instead of hype, so the company can see where AI genuinely helps.
• Partner across engineering and product teams to shape both the tools we use internally and the AI capabilities we ship to customers.
• Decide when to buy a proven solution, when to build alongside our product teams, and when a problem deserves something purpose built.
• Grow the talent around you. Mentor senior engineers, align principals across the organization, and raise the ceiling for what the team believes is possible.

At Atlassian, we strive to design equitable, explainable, and competitive compensation programs. We follow consistent hiring practices and account for each candidate's skills, knowledge, and experience when setting base pay within the range.
