  • Apply reinforcement learning or optimization techniques to continuously improve pricing and inventory control
  • Run A/B and multivariate tests to evaluate new pricing strategies and product features
  • Use causal inference to pinpoint what truly drives conversion and yield performance
  • Work with ML and Data Engineers to deploy, monitor, and retrain models in production
  • Ensure scalable, reliable data pipelines and robust feature engineering processes
  • Partner with Product, Engineering, and Commercial teams to align model outcomes with business objectives
  • Translate data-driven insights into actionable pricing and capacity strategies
