About the role

Founding, hands-on data engineering role focused on establishing Braintrust's data foundation, architecture, and self-serve analytics. You will define business entities, metrics, ingestion pipelines, and governance, partnering with executives across Product, Finance, GTM, and Engineering.

Responsibilities

  • Define the business entities, metrics, and semantics that Product, Finance, and GTM all build on
  • Design and build the core data models in SQL and dbt
  • Build and own ingestion from product events, CRM, and other business systems, including vendor APIs, webhooks, and sync gaps
  • Make architectural decisions by determining how storage, orchestration, and transformation evolve from here
  • Stand up self-serve analytics that includes building semantic models and trusted metrics that stakeholders can query without filing a ticket
  • Partner with Engineering and Product on usage data and event schemas as the product surface grows
  • Treat governance and reliability as part of the data model
  • Use AI to accelerate your own build, and keep the foundation clean and well-described enough that AI tooling on top of it has something reliable to stand on.

Qualifications

  • You've defined business entities and metrics, and built the models behind them
  • Strong command of SQL and dbt, and experience with a cloud warehouse (Snowflake or equivalent) and an orchestrator (Dagster, Airflow, or similar)
  • Enough engineering depth to own pipelines end to end. You can write and maintain production code, not only transformation models.
  • Clear judgment about data modeling, schema evolution, contracts, and lineage
  • Strong debugging instincts across a multi-system path, and the patience to trace a wrong number to its source
  • Ability to work directly with executives and functional leaders: clarifying vague requests, explaining how the data works, and negotiating priorities and tradeoffs
  • Comfort operating as the only data hire, balancing foundational architecture against urgent business needs
