Requirements

  • Experience designing evaluation metrics and harnesses that reflect real user experience.
  • Familiarity with the ML lifecycle: dataset operations, training pipelines, evaluation frameworks, deployment, and monitoring.
  • Experience shipping complex projects to production, ideally user-facing or online ML systems, and adapting as requirements change.
  • Good judgment about when to work independently and when to bring in teammates.
  • Experience contributing to technical direction, building consensus, and working well with product, infrastructure, and research partners.

Benefits

  • 401 (k) max employer match: 3.5% of compensation
  • 100% employer-paid health, vision, and dental benefits for you and your dependents
