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 Principal Machine Learning Engineer (P60) to join our new GenAI Modeling & Innovation Forge in Singapore. This is a hands-on technical leadership role where you'll push the boundaries of advanced GenAI modeling, rapid prototyping, and applied research-turning state-of-the-art techniques into high-impact innovations across Atlassian.
Advance GenAI Modeling with Knowledge
  • Design and build novel approaches for knowledge-grounded LLMs, embeddings, and multimodal modeling.
  • Explore fine-tuning, post-training, and retrieval-augmented strategies to adapt foundation models to Atlassian's data.
  • Lead technical explorations that expand the frontier of what's possible in applied generative modeling.

Prototype & Experiment Rapidly
  • Drive POC experimentation, from agentic workflows to novel GenAI-powered assistants.
  • Translate research ideas into fast, working prototypes that demonstrate user value.
  • Define and implement evaluation methods (groundedness, hallucination detection, human-in-the-loop) to measure success.

Provide Technical Leadership
  • Act as the technical anchor of a small tiger team (manager + ICs), mentoring engineers and scientists.
  • Influence design and implementation across retrievers, rankers, orchestration, and serving infrastructure.
  • Collaborate with product and platform teams to transition prototypes into scalable systems.

Shape Innovation Strategy
  • Contribute to the roadmap for the Forge as a global hub for advanced GenAI modeling and applied research.
  • Partner with peers across Rovo, Jira Search, Knowledge AI, and Platform to drive cross-team impact.
  • Champion responsible AI, groundedness, and data quality in all innovations.

What We're Looking For
Experience
  • Extensive experience in ML/AI engineering (generally 6+ years), with deep expertise in LLMs, NLP, or search.
  • Proven track record of building and shipping ML-powered or GenAI-integrated products.
  • Hands-on experience with retrieval-augmented generation (RAG), embeddings, hybrid retrieval, or agentic workflows.
  • Strong background in scaling ML systems from prototype to production.

Skills
  • Expert-level knowledge of GenAI ecosystems (OpenAI, Anthropic, Mistral, OSS) and fine-tuning/serving frameworks.
  • Deep technical skills across modeling, infrastructure, and orchestration (LangChain, LlamaIndex, vector DBs).
  • Strong prototyping ability, balancing speed with rigor in experimentation.
  • Ability to set technical direction and inspire peers with thought leadership.

Education
  • Master's or PhD in Computer Science, Machine Learning, or related field preferred-or equivalent industry experience.

Nice to Have
  • Experience with multimodal models, knowledge graphs, or semantic embeddings.
  • Familiarity with evaluation metrics for search/GenAI (NDCG, groundedness, human preference modeling).
  • Contributions to open-source ML frameworks or GenAI research communities.
  • Passion for mentoring, fostering innovation, and shaping a new AI hub in Singapore.

Why Join Us?
  • Play a founding role in Atlassian's Singapore-based GenAI Modeling & Innovation Forge.
  • Drive technical breakthroughs and deliver high-visibility prototypes with global impact.
  • Collaborate with world-class peers, rich enterprise data, and robust infrastructure.
  • Be part of a mission-driven, remote-first company where innovation is valued and amplified.
