About the role

  • Senior Data Engineer designing and scaling data pipelines for a go-to-market platform. Build and own systems that create a high-quality first-party contact dataset.

Responsibilities

  • Build the enrichment platform - Design and scale pipelines that process 100M+ contact records, integrating with large-scale contact data vendors.
  • Own data quality - Build deduplication, entity resolution, and record matching systems that merge contacts from multiple sources into a single high-quality record.
  • Optimize vendor economics - Create waterfall enrichment logic that maximizes coverage and freshness while minimizing per-record cost across a portfolio of data vendors.
  • Ship freshness infrastructure - Build systems that detect job changes, flag stale records, and trigger re-enrichment to keep the dataset current.
  • Instrument and measure - Create quality scoring, coverage dashboards, and accuracy metrics that give the business visibility into dataset health.

Requirements

  • 5+ years of data engineering experience, including 2+ years working with contact data, enrichment systems, or data infrastructure.
  • Deep experience with data vendor APIs and the economics of contact data (coverage rates, accuracy tradeoffs, cost per record).
  • Expert-level SQL and data modeling skills, with experience designing schemas for large-scale entity datasets.
  • Track record building production data pipelines using modern tooling (dbt, Airflow, Dagster, Spark).
  • Experience with entity resolution, deduplication, and fuzzy matching at scale.
  • Strong understanding of data warehousing (Snowflake, ClickHouse, BigQuery) and performance optimization.
  • Business-minded: you understand that data quality directly impacts revenue and can articulate tradeoffs in terms the GTM team understands.

Benefits

  • comprehensive benefits (including medical, dental, vision, and 401(k) options)
