Who We Are:
Travel is a force for good. At Expedia Group (Expedia, Hotels.com, Vrbo, Travelocity, Orbitz, Wotif, and others), our mission is to power global travel for everyone, everywhere—because we know that travel strengthens connections, broadens horizons, and bridges divides.

With unrivaled knowledge of the industry and advanced technology, we’ve built a marketplace that filters through millions of possibilities for travelers and partners worldwide.
About the Team:
The Marketplace Machine Learning Science team is launching a high-impact initiative focused on Customer Lifetime Value (CLV)—a key business metric that will shape long-term company performance and executive decision-making. As a Machine Learning Scientist III, you will lead efforts to build causal models and experimentation frameworks that optimize how we serve millions of travelers globally.
This is a high-visibility role with direct exposure to executive leadership and cross-functional teams across product, engineering, marketing, customer service, pricing, and more. You’ll be joining a zero-to-one initiative with strong leadership support and urgency to deliver impact starting immediately.
Strategic Impact & Visibility:
This role offers a rare opportunity to shape how Expedia Group measures and optimizes long-term customer value.

In this role, you will:
Lead the research and implementation of scalable machine learning and data science solutions end-to-end with engineering rigor
Apply causal inference techniques to understand drivers of customer lifetime value and measure the impact of business interventions (e.g., marketing, service, product features)
Design and execute robust experiments (e.g., A/B tests, quasi-experimental methods) to evaluate business strategies and validate model performance
Translate complex findings into actionable insights for both technical and non-technical stakeholders
Break down ambiguous business problems into structured, data-driven solutions
Stay informed on relevant ML and AI research, with support from Expedia’s learning and development resources
Collaborate with other machine learning and data science teams to foster a strong data science culture across Expedia Group
Minimum Qualifications:

Typically requires 4+ years of professional experience, though candidates with equivalent project or research experience are encouraged to apply
Strong hands-on experience in causal modeling and experimental design
Proven ability to analyze large, complex datasets and generate actionable insights
Pragmatic problem solver focused on scalable and effective methods
Ability to share ideas effectively with diverse technical and business audiences
