  • Hands-on experience building and maintaining evaluation suites and guardrails that prevent regressions

  • Make business and product metrics easily accessible for leadership via reliable pipelines and dashboards
  • Build internal tooling for robust experimentation
  • Create systems that make accidental regressions hard, such as pre-merge evaluation suites and automated guardrails
  • Set up pipelines for ongoing quality monitoring and reporting

  • 5+ years of professional experience as a Data scientist or in a similar role
