The Data Architect / Quality Assurance Engineer will help define, document, and improve the data models, standards, validation frameworks, and quality assurance practices that support the City’s enterprise data integration ecosystem. This position will work across departments, programs, systems, and technical teams to understand business processes, source-system behavior, data definitions, data quality issues, and integration needs. The role will help translate that understanding into enterprise data models, data contracts, validation rules, metadata, quality checks, and architectural guardrails that make City data more consistent, trustworthy, reusable, and scalable.The Data Architect / Quality Assurance Engineer will play a key role in reducing downstream errors, improving API and integration design, supporting data governance, and ensuring that enterprise data products are designed with quality and reuse in mind from the beginning. The position will support priority departmental and enterprise modernization efforts, while also contributing to broader enterprise data architecture and data quality work across CityGeo’s portfolio.We are looking for a candidate who can bridge business process analysis, data architecture, quality assurance, and practical implementation.
