• You have experience with orchestration and deployment tools like Airflow to deliver reliable, production-ready models that scale
• You have a background in dynamic pricing and promotion modeling, applying advanced methods to optimize strategy and outcomes

• You are flexible and curious, contributing beyond model development to the broader analytics landscape
• You are confident working independently while managing strong cross-functional relationships across multiple teams
