Principal ML/AI Software 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.
To help our teams work together effectively, this role is fully remote but requires you to be located in Turkiye.
What you'll do
We are looking for a Principal Engineer experienced in the ML/AI domain to drive the vision, development, and launch of AI-powered products and platforms at Atlassian. You will lead initiatives across two key areas:

• AI Foundation - Building scalable AI infrastructure and tools to expedite the development of AI-powered features across Atlassian's product teams.
• NextGen AI - Exploring cutting-edge AI applications (for example, chatbot experiences, generative AI features) to shape the future of our products.

This role requires strong technical leadership, balancing hands-on engineering, strategic decision-making, and cross-functional collaboration to ensure the successful end-to-end delivery of AI solutions.
Joining Atlassian is an opportunity to be at the forefront of industry transformation.

• Facilitate product and technical decisions, ensuring alignment with business goals.
• Drive platformization of AI/ML systems to improve scalability, reliability, and adoption across teams.
• Partner with customer teams to understand needs, build relationships, and expand the scope of AI adoption.
• Explore and apply state-of-the-art AI/ML techniques to solve novel product challenges.
• Evaluate in-house model development vs. third-party APIs for ML/AI solutions.
• Establish best practices for AI development, quality measurement, monitoring, and scalability.

Must-Have:

• 7+ years of experience in Machine Learning engineering, including hands-on work with training/inference pipelines, prompt engineering, and ML systems, demonstrating deep expertise in applied ML.
• Proven track record of tech-leading AI/ML products from conception to launch.
• Strong platform mindset - experience building reusable tools/infras to accelerate AI development.
• Strong programming skills in any OOO programming language - we're open to candidates from different tech backgrounds.

Nice-to-Have:
