Introduction to the Team

Expedia Group Advertising helps Expedia Group and its partners connect with travelers and understand the impact of advertising across Expedia Group brands and partner channels. Within Emerging Business Technology, the Measurement, Attribution & Data Platform organization builds the data, measurement, and attribution capabilities that translate advertising interactions and outcomes into trusted insights.

As a Data Scientist III, you will shape how we measure advertising performance and outcomes. You’ll apply statistical methods, causal inference, experimentation, and predictive modeling to complex, large-scale datasets-developing approaches that help distinguish the impact of advertising from other factors in a traveler’s journey. Your work will inform attribution, measurement, and reporting experiences used by advertisers and internal teams to make better decisions.

You’ll partner closely with engineering, product, and analytics stakeholders to define measurement problems, evaluate data quality and assumptions, and turn analytical methods into scalable, reliable solutions. You’ll bring scientific rigor to ambiguous questions, communicate findings and tradeoffs clearly, and help ensure that insights are actionable and trustworthy in production.

We’re looking for a data scientist who takes ownership of high-impact work, exercises sound judgment, and raises the bar for analytical quality. At this level, you’ll lead projects from problem framing through validation and adoption, influence measurement strategy, and help evolve the platforms and methods Expedia Group uses to understand advertising outcomes.

In This Role, You Will

• Analyze large, complex datasets to solve business and product challenges.

• Develop and apply statistical, machine learning, and experimentation methodologies to generate actionable insights.

• Partner with stakeholders across Product, Engineering, and the business to define problems and drive data-informed decisions.

• Build scalable analytical solutions, dashboards, and measurement frameworks.

• Communicate findings and recommendations clearly to technical and non-technical audiences.

• Mentor junior team members and contribute to analytics best practices.

Minimum Qualifications

• Bachelor's degree in Data Science, Statistics, Mathematics, Computer Science, Economics, Engineering, or a related quantitative field.

• 4+ years of experience in data science, analytics, or a related field applying statistical analysis, experimentation, machine learning, or predictive modeling to business problems.

• Advanced proficiency in SQL and Python, R, or similar programming languages.

• Experience designing and executing experiments, statistical analyses, and predictive models, and translating findings into business recommendations.

• Ability to independently manage analytical projects from problem definition through implementation and stakeholder adoption.

• Strong communication skills with experience presenting insights to both technical and non-technical audiences.

Preferred Qualifications

• Master's degree or PhD in a quantitative field.

• Experience developing, deploying, or monitoring machine learning models in production environments.

• Expertise in experimentation, causal inference, A/B testing, and advanced statistical methods.

• Demonstrated ability to influence business strategy and decision-making through data-driven insights.

• Experience mentoring junior team members and partnering with senior stakeholders.

• Familiarity with AI/ML applications, generative AI, and large-scale data environments.
