* Strong analytical and problem-solving skills, with the ability to guide teams through complex challenges while keeping business impact in focus.
* Experience across the full ML lifecycle, including data preprocessing, model training, evaluation, deployment, and monitoring in production environments.
* Expertise with MLOps tools and practices (e.g., MLflow, SageMaker, Docker, CI/CD pipelines), and the ability to set standards and best practices for the team.
* Excellent communication and presentation skills, capable of clearly articulating technical results and strategic implications to both technical and non-technical stakeholders, including senior leadership.
* Demonstrated track record of stakeholder engagement, leading cross-functional collaboration with product, engineering, and business teams.
* Solid foundation in statistics, including techniques such as hypothesis testing, significance testing, and probability theory.
* Comfortable working in an agile environment, driving iterative development cycles and mentoring cross-functional teams.
