Data Scientist

Responsibilities

• Design rigorous experiments and quasi-experiments to measure the causal impact of CS product launches and drive data-informed launch decisions.
• Build causal ML models to optimize Make Goods budget allocation and maximize business impact.
• Conduct causal inference analyses to quantify the long-term effects of product changes and uncover heterogeneous treatment effects.
• Deliver strategic insights on quality-cost tradeoffs, empowering leadership to deliver the best possible support experience to our community.
• Design and implement causal inference frameworks and statistical models to measure the impact of interventions, evaluate system performance and uncover opportunities for improvement.
• Build, evaluate and iterate on causal ML models that power high-stakes decisions, applying best practices across the full model lifecycle from feature engineering to production deployment.
• Develop frameworks to analyze tradeoffs between competing objectives (accuracy, coverage, user experience and operational cost), and propose strategies to improve overall effectiveness.
• Collaborate cross-functionally with Product, Design, Engineering, Operations, and Analytics to drive collaboration and innovation.
• Communicate learnings to leaders and stakeholders in a clear, compelling manner that drives informed, data-driven decision-making.
• Think strategically about how to scale and evolve data science capabilities within your domain, contributing to the long-term vision for how science drives platform outcomes.

Requirements

• 2+ years of industry experience in a quantitative analysis role with a Master's degree in a quantitative field (statistics, economics, computer science, etc.), or PhD in relevant fields.
• Strong knowledge of causal inference and experimental design.
• Strong knowledge of Bayesian modeling and statistical inference.
• Hands-on experience building and deploying statistical or ML models in production environments.
• Skilled in statistical programming (Python/R) and database usage (SQL).
• Proven ability to communicate clearly and effectively to audiences of varying technical levels.
• Ability to translate complex findings into compelling narratives that drive impact.
• Excellent project management, communication and collaboration skills.

Nice-to-Haves

• Expertise in optimization and tradeoff analysis between competing objectives.
