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.
At Atlassian, we’re on a mission to unleash the potential of every team. As part of that mission, we're investing deeply in Generative AI — pioneering advanced modeling and rapid innovations that accelerate how teams work, discover, and create.
We’re seeking a Senior Machine Learning Systems Engineer (P50) to join our new GenAI Modeling & Innovation Forge in Singapore. You’ll focus on building and scaling the systems that power advanced GenAI modeling, rapid prototyping, and applied research—bridging cutting-edge algorithms with reliable, high-performance infrastructure.
