📋 Description

• You will transform demand, occupancy, and purchasing behavior data into models that price a network with thousands of origin-destination pairs and multi-leg routes. • Conduct exploratory and statistical analysis to discover patterns, generate hypotheses, and guide modeling. • Model demand and no-shows per origin-destination pair using gradient boosting and time series methods, correcting for censored demand bias (unconstrained demand). • Estimate price elasticity and willingness-to-pay by segment and route as the basis for price optimization. • Model seat protection and capacity allocation (fare buckets) on multi-leg routes, balancing load factor and revenue. • Design A/B tests and causal inference analyses that validate price changes and measure real uplift, with clear statistical rollout criteria. • Ensure interpretability (e.g., SHAP) to defend each price to the business and regulators. • Design strategies for routes with limited historical data, starting from literature priors and evolving to ML solutions, on a per-tenant basis.

🎯 Requirements

• Strong quantitative background (Statistics, Economics, Mathematics, Engineering, Computer Science or related) and a solid foundation in probability, inference, and experimental design. • Exploratory data analysis (EDA) and strong storytelling and visualization skills. • Classical ML (regression, classification, clustering) and time series; familiarity with deep learning (PyTorch or TensorFlow). • Python and the Data Science ecosystem (pandas, scikit-learn, statsmodels); SQL for large-scale data. • Causal inference and/or A/B testing and impact measurement. • Clear scientific communication and comfort with AI-assisted development (e.g., Claude Code).

🏖️ Benefits

• Remote work • Project duration: 6 months, with possibility of extension or internal hire.
