## Description

My client is hiring a Senior Product Data Scientist to play a senior, highly strategic role within their product data organization. This is a rare opportunity to sit at the center of product strategy, experimentation, and causal inference, with real influence on how data drives decision-making at the executive level.

In this role, you'll lead the evolution of experimentation and measurement across the product, uncover non-obvious insights from complex datasets, and help leadership clearly understand true impact-not just correlation.

You'll act as a trusted thought partner to Product, Engineering, Design, Finance, Marketing, and exec leadership while mentoring and leveling up other data scientists.

Key focus areas include:

 * Owning and driving the experimentation roadmap across the product
 * Designing and analyzing advanced A/B tests, multivariate and Bayesian experiments
 * Applying causal inference techniques (DiD, synthetic controls, PSM, IVs) when RCTs aren't possible
 * Building KPI and measurement frameworks that connect product metrics to business outcomes
 * Translating complex statistical findings into clear, actionable narratives for senior leadership
 * Partnering with Data Engineering to scale experimentation tooling and self-serve analytics
