This role involves collaboration across multiple domains and stakeholders, offering the opportunity to broaden your expertise while working on complex, real-world data challenges.

Your tasks

• Work collaboratively with both technical and non-technical stakeholders, translating complex or ambiguous business logic into scalable data solutions

• Contribute to the semantic layer (LookML) to ensure consistent, scalable reporting and enable self-service analytics across multiple domains

• Take ownership of data quality, implementing testing, monitoring, and documentation; proactively detect and resolve issues in business-critical data pipelines

• Support reliable data workflows, including working with orchestration tools such as Airflow/Astronomer where needed

• Contribute to and uphold strong analytics engineering practices, including code reviews, reusable patterns, and reducing technical debt

• Balance work across multiple data domains and shared definitions, which requires adaptability and effective context switching

Requirements

• Min. 5 years of hands-on experience with dbt and modern cloud data warehouses (BigQuery)

• Proficiency in SQL skills and experience building well-structured, reusable models in a layered architecture

• Ability to translate unclear or messy business requirements into clean, performant, and maintainable data transformations

• Familiarity with Git-based workflows, version control, and CI/CD practices in analytics engineering environments

• Comfort working in environments with high engineering and governance standards

• Strong collaboration and communication skills, with the ability to engage proactively with stakeholders beyond data teams

• Interest in developing expertise across domains such as payments, credit, and fraud/AML, rather than focusing narrowly on a single area
