Own machine learning projects from initial concept through production deployment, measurement, and continuous improvement.
Develop scalable data and modeling approaches using large, complex datasets.
Design robust system and model architectures that meet requirements for quality, latency, scale, reliability, privacy, and cost.
Build and improve machine learning solutions across areas such as information retrieval, search ranking, personalization, natural language processing, deep learning, and large language model applications.
Design and execute rigorous experiments, offline evaluations, online tests, and error analyses to measure model quality and product impact.
Collaborate with product, engineering, data science, analytics, and platform teams to integrate AI capabilities into Atlassian products and services.
Translate research and emerging AI techniques into reliable, maintainable, production-quality systems.
Identify opportunities to improve model performance, operational efficiency, developer experience, and customer outcomes.
Communicate technical decisions, trade-offs, results, and recommendations clearly to both technical and non-technical audiences.
Mentor and support machine learning engineers, contribute to technical strategy, and help establish best practices across the organization.
