Pricing Science & Modeling

• Design the pricing methodology for multiple channels (direct + OTAs) : demand forecasting, price elasticity estimation, competitor response, inventory / lead-time effects, seasonality & events.
• Build hybrid rules + ML systems that start simple (guardrails, explainability) and graduate to Bayesian / causal, RL / bandit approaches where appropriate.
• Define KPIs (revenue / seat, conversion, occupancy, margin) and attribution logic; build offline / online evaluation, backtests, and simulation / sandbox environments.
• Partner closely with Product to keep price recommendations explainable and operator-friendly.
