# Senior Data Scientist - Payments (Inference) at Airbnb

Airbnb's Payments Data Science team is seeking a senior data scientist to lead quantitative measurement and fraud mitigation efforts across their global marketplace. You'll develop causal inference frameworks, design experiments in their two-sided marketplace, and build machine learning models to optimize payment safety and efficiency. Your work will directly inform decisions made by senior leadership across payments, finance, and trust functions, requiring a rigorous, evidence-based approach to complex problems without established playbooks.

Day-to-day responsibilities span causal inference methodology, ML model evaluation and development, optimization simulations, and stakeholder communication. You'll conduct root cause investigations, build predictive models to classify user behavior, support evaluation of AI/LLM systems, and deliver research reports that drive product roadmaps. The role emphasizes balancing competing tradeoffs while ensuring transactions remain fast, safe, and compliant at global scale.

This position is ideal for someone with 5+ years of quantitative analysis experience (or 3+ years with a PhD) holding a Master's in math, economics, statistics, or related field. You should demonstrate strong expertise in causal inference, experimentation, statistical modeling, and end-to-end machine learning development, with solid statistical programming skills. The role is remote within the USA.
