Atlassian is looking for an experienced and visionary Principal Machine Learning Engineer to join our FinOps Insight team based in Australia.

Your future team

We are a team of people with backgrounds in FinOps Analysts and Data Engineers. We operates within the Cloud FinOps organisation, which is part of the Core Engineering department.

Our org is on a mission to drive cost-efficiency to sustain Atlassian’s growth with our team focusing on bringing relevant data and compelling insights, helping teams make informed decisions and sustain their unit economics.

This role is ideal for someone who is both strategic and hands-on, and for someone who thrives on curiosity, enjoys solving complex problems, and is passionate about harness the power of AI to accelerate time to impact without scaling up teams

What You’ll Do

• Drive the development and implementation of the cutting edge machine learning algorithms, training sophisticated models that power financial insights, including anomaly detection, forecasting, and NLP-driven analytics on financial health

• Develop scalable ML pipelines to support timely anomaly detection and cost optimisation.
• Design system and model architectures, conduct rigorous experimentation and model evaluations
• Work closely with data engineers to aggregate and structure cloud financial data for effective ML applications.
• Ensure MLOps best practices, including model deployment, monitoring, and continuous learning
• Collaborate with FinOps Analysts, engineering, and product teams to translate ML insights into business impact.
• Collaborate with cross-functional teams to integrate AI-driven intelligence into our tooling
• Optimise models for performance, interpretability and efficiency in real-work applications
• Coach data engineers, fostering a culture of learning and innovation in ML and AI
• Master or PhD in a quantitative subject (Statistics, Mathematics, Computer Science, Operations Research, or relevant work experience)
• 5+ years of related industry experience in the data science domain
• Expertise in anomaly detection, forecasting models, NLP, and optimisation techniques.
• Proficiency in ML frameworks (e.g.TensorFlow, PyTorch, Scikit-Learn) and MLOps tools.
• Strong programming skills in Python, SQL and with the ability to write performant production-quality code, experience with Spark, cloud platforms and data environment (AWS, GCP, Azure / Databricks)
• Deep knowledge of ETL and software engineering tools, incl. Kafka and Airflow
• Ability to balance innovation with practical execution, delivering solutions that drive measurable impact.
• Ability to communicate and explain data science concepts to diverse audiences and translate ML insights into actionable cost efficiency strategies, craft a compelling story
• Experience building and scaling machine learning models in business applications using large amounts of data
• Focus on business practicality and the 80/20 rule; very high bar for output quality, but recognise the business benefit of “having something now” vs “perfection sometime in the future”
• Agile development mindset, appreciating the benefit of constant iteration and improvement

It’s great, but not required, if you have

• Familiarity with FinOps and cloud financial management
• Hands-on experience with cloud cost attribution, cost modelling and optimisation.
• Experience with agent-based AI frameworks like CrewAI and Langchain, along with LLMs and LGMs
• Excelling in solving ambiguous and complex problems, being able to navigate through uncertain situations, breaking down complex challenges into manageable components and developing innovative solutions
