Required qualifications: 10+ years building large-scale products for sophisticated audiences; experience designing interfaces and supporting technology platforms in enterprise applications; technical leadership skills including setting direction, writing specs, and influencing across teams; BA/BS in mathematics, statistics, data science, or related field (graduate degree preferred).
Desired experience includes: Go, Python, or similar languages; event-driven architectures and large-scale data processing; cloud environments (AWS, GCP) and data stores (ClickHouse, Redis, DynamoDB, Kafka); experiment lifecycle tooling and flag-experiment integration; familiarity with competitive products (Statsig, Eppo, GrowthBook, Optimizely); funnel analysis, causal inference, or Bayesian experimentation.
