Working at Atlassian

Responsibilities
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.
Qualifications
12+ years in hands on technical leadership roles, with end to end ownership across the software development lifecycle.
A track record of setting technical direction across a function or organization, not just one team, and bringing many engineers with you.
Deep expertise building large scale systems in one or more of: distributed systems and cloud infrastructure, developer platforms, data and measurement systems, or applied AI.
Genuine technical depth. You still write code, go deep into hard problems, and raise the quality bar for everyone around you.
Strong judgment on cost, scale, and return on investment. You treat efficiency as a real engineering problem.
Experience influencing decision makers and turning ambiguity into a clear plan.
Real excitement for an open, unmapped space. Building software with AI is being invented now, and you want to help invent it.
Nice to have:
Hands on experience with modern AI systems such as large language models, agents, or AI developer tools.
Background in developer experience, developer productivity, or the tooling and infrastructure behind CI and CD.
