• Identify opportunities for prescriptive analytics and automation in key product and marketing workflows.
• Support development of reusable ML pipelines for production-scale use cases in product recommendation, lead scoring, and SEM planning.
Collaboration & Communication
• Present insights and recommendations to a variety of stakeholders — from ICs to executives — in a clear and compelling manner.
• Translate business needs into data problems, and complex findings into strategic action plans.
• Work cross-functionally with Engineering, Product, BI, and Marketing to deliver and deploy your work.
