Lead the design and maintenance of enterprise-grade dimensional models using Kimball standards. Design fact tables, dimensions, conformed dimensions, and surrogate key strategies. Ensure models are optimized for Redshift performance (distribution styles, sort keys, query patterns). Review and refactor existing models to improve usability, performance, and scalability. Write and optimize complex SQL queries on Amazon Redshift for analysis, validation, and performance tuning. Profile source data to validate assumptions and inform modelling decisions. Support downstream analytics and BI teams with query optimization and model usage guidance. Partner with data engineers and analysts to align modelling decisions with ELT implementation. Facilitate requirements and modelling workshops with business stakeholders and data knowledge workers. Translate business concepts, KPIs, and metrics into well-defined dimensional structures. Act as a trusted advisor to business and analytics teams on data interpretation and usage. Communicate complex data concepts clearly to non-technical audiences. Define and enforce modelling standards, naming conventions, and design patterns. Document data definitions, business rules, and assumptions. Support data lineage, impact analysis, and enterprise data consistency. Contribute data governance and best-practice frameworks. Provide guidance and mentoring to junior modelers and analysts. Review data models and SQL developed by others. Influence architectural and design decisions across the data platform.
