Expedia Group is an American travel technology company headquartered in Seattle, Washington, that runs consumer brands such as Expedia and Vrbo alongside a B2B travel network and a travel advertising business. It began in 1996 as a division of Microsoft, went public in 1999, was spun off from IAC in 2005, and its portfolio also includes Hotwire, Orbitz, Travelocity, Wotif and Trivago. Current openings cover software development and machine learning engineers and scientists, product managers, data engineers, account managers for hotel partners, and analysts in Seattle, London, Austin and Chicago.

At Expedia Group, we help travelers explore the world, one journey at a time. As a global travel company powered by passionate people, trusted partnerships, and leading technology, we connect travelers, partners, and advertisers through our consumer brands, B2B network, and travel advertising business.

Here, you'll do meaningful work that helps millions of people discover, book, and experience travel with more ease, confidence, and joy. Our five Behaviors-Traveler First, Think Big, Operate with Excellence, Ownership Mindset, and Succeed Together-help foster a supportive environment where people can grow their careers and have the flexibility, benefits, and support to do their best work. Join us and build for travelers everywhere.

Expedia Group is seeking a talented and experienced Data Scientist III to join our Hotels.com Analytics team. In this role, you will own analytics for some of Hotels.com’s most important growth domains - such as customer growth, loyalty & retention, large-scale merchandizing campaigns, and website performance.

You will frame ambiguous questions, design and execute rigorous analyses and experiments, and translate insights into decisions that shape the Hotels.com strategic priorities, product roadmap, and marketing tactics. You’ll work closely with product, marketing, supply, and collaborate with central analytics teams. Using tools like SQL, experimentation platforms, and occasionally Python, you will drive impact at scale.

This is a high-impact, individual contributor role where your work will directly influence how millions of travelers discover, choose, and book hotels on Hotels.com.

In this role, you will:

  • Deep dive into Hotels.com customers and booking data to uncover patterns, diagnose issues, and suggest clear growth and optimization paths.
  • Design, conduct, and analyze experiments (A/B tests, Pre/Post) for product and marketing initiatives, leveraging industry best practices and internal experimentation platforms.
  • Develop and leverage a best-in-class analytical toolkit (SQL, Python, statistical and causal methods, experimentation frameworks) to extract insights and make data-driven recommendations.
  • Collaborate closely with cross-functional teams (Hotels.com Product, Loyalty, Marketing, Supply, as well as other Analytics teams) to identify key business challenges and provide analytical insights and recommendations to support decision-making.
  • Drive action to improve Hotels.com KPIs (such as revenue, engagement, retention, and marketplace health), utilizing the 80/20 rule to focus effort on the most impactful results. Demonstrate creativity and persistence in overcoming roadblocks.
  • Develop and maintain clear and user-friendly dashboards and reports to track and analyze KPIs (e.g., customer value, engagement, campaign outcomes). Train stakeholders on their usage.
  • Be curious and constantly monitor key metrics and trends to proactively suggest actions, test ideas, or highlight business opportunities for Hotels.com.

Experience and Qualifications:

  • Mastery of SQL and experience working with complex data ecosystems.
  • Proven track record in translating big data into strategic and actionable business recommendations; driving end-to-end processes through data extraction, analysis, insight, implementation, and evaluation.
  • Excellent communication and presentation skills, with the ability to present complex information clearly and concisely.
  • Robust experience applying statistical methods and experimentation techniques such as A/B testing and Pre/Post analyses.
  • Demonstrated experience working with Director+ stakeholders to influence decisions and drive outcomes.
  • Solid business acumen and problem-solving abilities.
  • Strong technical foundation in analytics and data storytelling.
  • Ability to appropriately visualize quantitative analyses for both presentations (e.g., PowerPoint) and reporting purposes (e.g., Tableau).
  • Relevant degree in a quantitative discipline such as Mathematics, Data Science, Engineering, or similar is preferred.
  • Experience in e-commerce or the travel industry is a bonus.
