Requisitos e responsabilidades
Conteúdo da vaga extraído em seções para revisão mais rápida.
Responsibilities:
- Build the experimentation statistical engine — hypothesis testing, sequential analysis, variance reduction (CUPED, Winsorization), power analysis. Ensure statistical correctness across all experiment types.
Responsibilities:
- Design warehouse-native experimentation that runs analysis inside customer warehouses (Snowflake, Databricks, Redshift, BigQuery). Build modular, warehouse-agnostic abstractions for rapid new backend support.
Responsibilities:
- Lead adaptive experimentation — contextual bandit systems, Bayesian optimization, automated allocation beyond simple A/B tests.
Responsibilities:
- Drive the platform roadmap with product, design, and data science. Shape what we build, not just how.
Responsibilities:
- Collaborate cross-functionally with Warehouse Integrations, SDK, Platform, and Data Science teams.
Responsibilities:
- Mentor engineers and raise the team's bar for statistical rigor and system design.
- Own operational excellence — monitoring, observability, incident response, on-call. Robust telemetry and alerting.
Qualifications:
- 10+ years building large-scale experimentation platforms, statistical analysis systems, or data-intensive backend services.
Qualifications:
- Applied-statistics knowledge: hypothesis testing, sequential analysis, variance reduction (CUPED), power analysis, experiment design. Comfortable with frequentist vs. Bayesian trade-offs.
Qualifications:
- Experience with adaptive experimentation ML — contextual bandits, Thompson sampling, Bayesian optimization, or RL-based allocation.
Qualifications:
- Track record designing warehouse-agnostic systems across Snowflake, Databricks, Redshift, BigQuery, or similar.
Qualifications:
- Expertise in Go, Python, or similar for backend services and statistical computation.
Qualifications:
- Experience with event-driven architectures, data pipelines, and large-scale data processing.
Qualifications:
- Cloud environments (AWS, GCP) with infrastructure-as-code.
Qualifications:
- Technical leadership: setting direction, breaking down complex problems, influencing across teams.
Qualifications:
- Ability to translate statistical concepts for product and engineering audiences.
