Customer Service AI (Booking.com)

We are extending our AI capabilities in Customer Service at Booking.com and are looking for a Data Scientist who is passionate about turning data into meaningful insights and measurable business impact.

You will explore large-scale datasets, design and evaluate experiments, and work closely with cross-functional teams to shape how AI improves customer and partner experiences. You should be comfortable working independently, communicating clearly with both technical and non-technical audiences, and driving projects from exploration to measurable outcomes.

Conduct data exploration and visualization to uncover insights that guide AI and operational decisions.
Design, analyze, and interpret A/B tests and other experimental setups.
Measure the impact of AI solutions and communicate findings to stakeholders.
Collaborate with Product, Engineering, and Operations to turn insights into scalable improvements.
Own the design and delivery of entire Data Science solutions based on business requirements, bringing them from the initial idea-generation phase to implementation independently.
Work autonomously on consuming data, preparing it for data science use, translating business problems to data stories, and solving them effectively by applying suitable statistical data analysis and modeling methods.
Work primarily within the scope of their team to deliver work that informs business decisions for the product/business topic they currently work on, occasionally collaborating across multiple teams.
Design and interpret quantitative experiments to objectively guide key business decision making.
Identify and manage stakeholders in operational, project-based, and managerial roles; communicate complex analysis results clearly.
Actively support junior colleagues through coaching, mentoring, and setting a good example.
Be flexible in adopting existing internal and external Data Science approaches, proposing and spotting opportunities to apply new approaches and expanding technical competencies.
Use Data Science for impact while learning to incorporate scalability, reproducibility, and long-term orientation.
Contribute to the community by supporting community projects, actively participating in community strengthening activities (e.g., recruitment), and connecting with peers beyond their area.
Collaborate with peers in related crafts (e.g., Data Engineering) and anticipate data needs.
Ensure quality of work via validating through peer review.
Influence business decisions within their specific area (e.g., product team).

Requirements

Strong experience in Python for data analysis and modeling.
Hands-on experience with Databases (especially Snowflake) and PySpark for large-scale data processing.
Knowledge of Causal Inference and experimental design techniques.
Excellent communication and storytelling skills.
Independent, proactive, and comfortable working in fast-paced environments.
Must be knowledgeable about the larger data ecosystem at Booking and how it relates to the work they do.
Must be knowledgeable with the operational, tactical and strategic goals of their area and have high level knowledge of the goals of their wider area.
