• Lead and mentor a team of MLOps engineers, fostering technical growth and a culture of operational excellence • Define and drive the MLOps roadmap, aligning infrastructure capabilities with Research, Engineering and product objectives • Establish best practices, standards, and processes for ML infrastructure, deployment, and operations • Own technical decision-making for ML infrastructure architecture and tooling choices • Architect and oversee scalable, automated machine learning pipelines, CI/CD workflows, and orchestration frameworks • Drive the design and implementation of robust model serving infrastructure using platforms like Triton, TorchServe, TensorFlow Serving, and KServe • Define inference architecture strategy optimized for ultra-low latency and high throughput • Design and maintain feature stores, robust data pipelines, and scalable storage solutions to efficiently handle large volumes of data • Collaborate with research teams to bridge the gap between experimentation and production • Define logging, alerting, and monitoring strategy to track model performance, drift, and system reliability

• Want to apply AI to real projects with direct business impact, instead of just POCs that never reach production? • We are looking for a Senior Artificial Intelligence / Machine Learning Engineer to lead cutting-edge solutions in a modern, data-driven, 100% remote environment. • You will be part of a small, autonomous team with direct contact with product and the freedom to propose architectures and technologies. • Design, train, and put ML/Deep Learning models into production. • Build data and MLOps pipelines (training, versioning, monitoring). • Work side by side with Product and Engineering to understand problems and metrics. • Rapidly prototype and evolve solutions into scalable production systems. • Optimize model performance, cost, and quality in the cloud. • Drive AI engineering best practices within the team (code review, standards, testing). • Explore and apply LLMs, NLP, and generative models where appropriate.

As a Principal Machine Learning Engineer, you will drive the development and implementation of cutting-edge machine learning algorithms, training sophisticated models, and collaborating with product, engineering, and analytics teams to build AI functionalities into Atlassian products and services. Your daily responsibilities will encompass a broad spectrum of tasks - designing system and model architectures, conducting rigorous experimentation and model evaluations, and providing guidance to emerging ML engineers. Your role is pivotal, ensuring AI's transformative potential is realized across our offerings. Technical Leadership & Execution - Drive complex decisions that impact the work of teams and change their technical direction over multiple quarters - Regularly tackle the largest and most complex problems on the team, from technical design to launch - Set the direction of systems and capabilities, balancing progress over perfection - Determine plans-of-attack on large projects and solve complex architecture challenges Model Development & Experimentation - Design, develop, and deploy production-grade ML models (e.g., ranking, retrieval, LLM-based systems) to optimize user experience and achieve business objectives - Conduct meticulous experimentation and model evaluations, backing decisions with data - Develop robust feature engineering practices to ingest, process, and serve features for offline training and online inference at scale - Oversee end-to-end deployment of ML solutions into production, ensuring continuous evaluation, monitoring, and improvement Cross-Functional Collaboration - Collaborate closely with product managers, designers, and engineering teams to integrate AI/ML capabilities into products - Partner across engineering teams to take on company-wide programs spanning multiple projects - Communicate complex technical concepts clearly to both technical and non-technical stakeholders Mentorship & Organizational Impact - Mentor and guide junior and senior engineers, fostering a culture of innovation, collaboration, and continuous learning - Actively share knowledge and expertise through mentoring and coaching beyond direct reports - Contribute to programs of work that scale across the department - Identify, solve, and bridge gaps/problems across teams using experience and expertise Decision Making & Direction - Quickly collate and analyze key decision parameters, balancing speed, risk, and impact appropriately - Limit ambiguity and risk by experimenting and prototyping - Understand how contributions of multiple capabilities fit into larger products and platforms At Atlassian, we strive to design equitable, explainable, and competitive compensation programs.
