Role description

The Data Analytics Engineer II operates as a fully independent contributor on data pipelines and data models of moderate complexity, supporting the cross-brand data, reporting, and analytics needs of Booking Holdings. This role takes end-to-end ownership of well-scoped deliverables—from ingestion through transformation to enablement of reporting—within an established framework set by senior peers and the Solutions Architect.

Success in this role means consistent, high-quality delivery on data products for the business areas served by the team (such as Finance, FP\&A, Treasury, Procurement, Market Intelligence and others), while building a strong foundation in the team's tooling (Snowflake, dbt, Dagster, Python, AWS, Terraform) and growing technical judgment under guidance from Senior Engineers and the Solutions Architect.

This role provides a hybrid way of working with an onsite presence of 2 days/week.

Key Job Responsibilities and Duties

• Pipeline Development: Builds and maintains data ingestion, transformation, and orchestration pipelines on Snowflake, dbt and Dagster (or Airflow/equivalent) under established team standards, ensuring data is delivered on time and to agreed quality.
• Data Modeling on Snowflake: Implements dimensional data models on Snowflake based on requirements gathered by Business Analysts and Product, following team conventions for naming, layering, and documentation; exposure to other modeling approaches (e.g. Data Vault) is a plus.
• Python for Data Analytics Engineering: Writes clean, testable Python—including object-oriented code—for Dagster assets, sensors and IO managers, as well as for general Data Analytics Engineering tasks.
• Source Integration: Integrates data from a wide variety of sources (ERPs, transactional systems, SaaS tools, flat files, spreadsheets, etc.), with awareness of the relevant business semantics.
• Quality, Testing \& Monitoring: Writes tests (dbt tests, custom checks), implements basic data quality monitoring, and proactively investigates anomalies for the pipelines they own.
• Operational Excellence (Awareness Level): Works within the team's CI/CD, Git, Docker, and Terraform setup with growing independence; contributes to infrastructure-as-code and DataOps practices under guidance of senior peers.
• Collaboration: Partners daily with other Data Analytics Engineers, the Reporting team, Business Analysts and the Product Manager to translate requirements into pragmatic technical solutions, escalating ambiguity early.
• Documentation \& Knowledge Sharing: Documents the pipelines, models, and decisions they own and shares learnings with the team through code reviews and informal knowledge sessions.
