- Validate PostgreSQL event schemas and DynamoDB read models
- Maintain detailed data lineage and field-level mapping
- Work closely with external vendors, engineers, DBAs and business stakeholders

Required experience:

- 8+ years’ experience in data architecture
- Extensive SQL Server and T-SQL expertise
- Proven ownership of complex, large-scale data migrations
