As a Senior Principal Machine Learning Engineer, your role will be instrumental in steering the development and deployment of advanced machine learning algorithms and system architecture. You will be tasked with training complex models and working in close collaboration with product, backend/front end engineering, and analytics teams to seamlessly integrate AI functionalities into every Atlassian product and service. Your day-to-day responsibilities will span a wide range of tasks, including designing system and model architectures, conducting meticulous experimentation and model evaluations, and mentoring budding ML engineers. Your role extends beyond these tasks, playing a crucial part in harnessing the transformative power of AI across our product suite.
Your role and impact:

• AI-Powered Atlassian Integration: Craft and implement innovative machine learning models in Atlassian tools.
• Advanced Data Analysis: Dive deep into vast datasets to extract meaningful insights. Your work will power the AI models to understand complex user interactions and content within Atlassian tools to propel team work forward across the globe.
• Robust Model Development: Design, build, and refine models that can accurately perform tasks such as topic and entity extraction, search ranking, and retrieval augmented generation at scale.
• Collaborative Innovation: Join forces with product managers, designers, and developers. Your collaborative efforts will ensure that AI features are not only powerful but also intuitive and user-friendly.
• AI Evangelism: Be the voice of AI within the team. Educate and inspire your colleagues about the potential of AI, leading workshops and knowledge-sharing sessions.

On the first day, we'll expect you to have

• Ph.D. or Master's degree in Computer Science, Machine Learning, Artificial Intelligence, or a related field.
• 8+ years of experience in machine learning, with a focus on large-scale model development and optimization.

• Familiarity with model optimization techniques, including quantization, pruning, and knowledge distillation.
• Strong problem-solving skills and ability to work in a fast-paced, collaborative environment.
• Excellent communication skills and ability to translate technical concepts for diverse audiences.

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

• Experience with LLMs and domain-specific fine-tuning.
• Knowledge of cloud-based ML platforms (e.g., AWS, GCP, Azure).
• Experience working in a consumer or B2C space for a SaaS product provider, or the enterprise/B2B space
