pipeline design, model development, deployment, and monitoring.
• Make key architectural and design decisions to ensure our ML systems are scalable, reliable, and
efficient.
• Navigate project requirements, creating clear plans of action and defining technical roadmaps.
• Optimize complex data pipelines and ML models for performance.
• Mentor junior engineers on the team, fostering their growth and ensuring high technical
standards.
• Act as the technical point of contact for your projects, managing communication with product
managers and other stakeholders.
• Cultivate a team environment focused on continuous learning, where innovative audience
measurement methodologies are developed and refined through collaborative effort

Basic Qualifications:
• Master’s or Bachelor’s degree in Engineering, Mathematics, Statistics or a related field.
• A proven track record of owning and shipping production machine learning systems.
• Deep expertise in classification models, regression models, anomaly detection, boosted models,
deep learning and simulation problems, particularly with large datasets.
• Deep expertise in ML concepts, data engineering, and MLOps practices.
• Proficiency in Python and SQL.
• Must have deployed E2E ML systems by automating training and inference pipelines.
• Hands-on experience with distributed computing frameworks like Apache Spark.
• Experience with workflow orchestration tools (e.g., Airflow) and MLOps.
