About the Team The Data Platform and Observability Engineering (DPOE) team is building Workday’s next-generation data-product platform the compute, storage, catalog, orchestration, governance, and developer workflows that engineering and analytics teams use to create and operate production data products and marts. We own the services and infrastructure behind a modern lakehouse stack: dbt Core, Airflow, Trino, Apache Iceberg, Amazon S3 Tables, AWS Glue Catalog, access control, and a visualization layer such as Apache Superset or Metabase. We treat the platform as a product. Our roadmap is how Workday teams model, test, query, and govern high-volume data without each standing up a stack of their own. About the Role ​Own the technical vision and architecture for Workday’s data-product platform — a highly scalable lakehouse that lets teams build, govern, and operate data products and marts. This is a hands-on, high-autonomy role for an engineer who can design the platform end-to-end (modeling and dbt, orchestration, distributed query, table format, catalog, security, and infrastructure as code) and who still writes and reviews highly performant analytical SQL. You will set technical direction across multiple teams, mentor senior and staff engineers, and act as the primary architect and escalation point for the platform — from project and pipeline design through query performance, governance, and reliability. • Architect and build the data-product platform on dbt Core, Airflow, Trino, Apache Iceberg, S3 Tables, and Glue Catalog, designed for high-volume ingestion and interactive query performance. • Own the platform path teams use to ship products: project structure, orchestration, CI/CD, environments, semantic / metrics definitions, and operational support. • Drive performance and scaling across modeling and query paths: Iceberg layout and maintenance, partitioning, incremental processing, compression, and Trino tuning under production load. • Lead HA/DR design for platform services — multi-AZ resilience, failover, backup/restore, and recovery objectives appropriate to a shared production platform. • Design security and access-control architecture, including authentication and authorization for multi-tenant data access across catalog, compute, storage, and visualization. • Use Terraform to define how the platform is built and evolved; set the bar for infrastructure, environments, and blast radius. • Own operational excellence: monitoring, alerting, capacity planning, safe reruns and backfills, and participation in an on-call rotation for the platform. • Evaluate and introduce n
