What This Person Owns
The infrastructure every data-driven team at Mercor runs on: Snowflake, Fivetran, Airflow, and Hex. You own how data is organized, who can access what, what it costs to run, and how reliably it operates. This is a foundational hire on a new Data Platform team, you'll help set the standards other engineers build against.
What They Do Day-to-Day
– Bring structure and clear ownership to how data is organized in Snowflake across projects and teams
– Design narrow, role-based access controls, and partner with automation so access is granted and revoked as people join, change teams, or leave
– Extend row access policies and PII masking across all sensitive datasets
– Migrate data from a variety of vendor and internal sources into properly owned, governed homes
– Own Fivetran connector health and cost, Airflow/Astronomer pipeline reliability and on-call, and Hex governance across company-wide dashboards
– Monitor and right-size Snowflake warehouse spend
– Help build CDC/streaming ingestion and other internal data platform tooling
What We're Looking For
– Hands-on experience with Snowflake administration: roles, grants, warehouses, cost/performance tuning
– Experience designing data access and governance models (RBAC, row-level security, PII) at scale
– Comfort owning vendor tooling end to end (Fivetran, Airflow/Astronomer, or similar), including on-call
– Track record migrating or re-architecting live production data systems without breaking dependent teams
– Strong SQL and Python, with infrastructure fluency to make judgment calls, not just execute a spec
– Experience owning CDC/streaming pipelines in production (Debezium, Kafka, Snowpipe Streaming or similar), including reasoning about delivery semantics, partitioning, and safe cutovers between systems.
