- Design, implement,



and operate large-scale ETL/ELT pipelines and workflow orchestration to ensure data is clean, accurate, versioned, and accessible
- Define data modeling, partitioning, schema evolution, and versioning conventions so datasets remain queryable, interoperable, and reproducible at scale
- Establish and maintain authoritative data catalogs, including schemas, metadata, lineage, sensitivity labels, and access policies
- Validate released datasets against their sources for completeness, correctness, schema consistency, and query performance, defining objective acceptance criteria
- Work closely with Machine Learning and AI Engineers to make data products directly consumable by analytics, APIs, and AI/agent workflows
- Collaborate with clients and cross-functional teams to scope requirements, lead technical sessions, and document architectures for knowledge transfer and internal ownership
- Mentor and support other data engineers, reviewing designs and code and raising the team's engineering standards
- Stay up to date with emerging trends in data engineering — open table formats, data catalogs, orchestration — and drive their adoption where they add value
