Senior Data Scientist, Causal Science (45539)

Overview

We are looking for a Senior Data Scientist to lead the evaluation strategy for our most dynamic personalization surfaces. Working closely with the Presentation Pod, you will ensure that visual optimizations for Artwork, Marquees, and Display items are spearheading true causal lift. You will be the primary scientific partner for validating high-velocity, Bandit-based systems. This is an Independent Contributor role, meaning you are trusted to solve ambiguous problems where standard A/B testing often fails. You will design and implement counterfactual analysis frameworks and off-policy evaluation methods to measure the performance of contextual bandits. You will raise the bar for the team by anticipating experimentation risks and mentoring junior analysts in the nuances of causal inference.

Why This Role Matters
Validating the Gateway: You ensure the Presentation pod's visual optimizations are statistically sound and causally effective.
Bandit Mastery: You solve the unique task of evaluating "always-on"learning systems where traditional group-based splits are insufficient.
Scientific Integrity: You protect the organization from "false wins" by applying rigorous counterfactual analysis and bias correction.

Responsibilities

Design Complex Experiments: Lead the design of experimentation frameworks for contextual bandits, focusing on reward definition and exploration strategies.
Counterfactual Evaluation: Develop and scale off-policy evaluation (OPE) methods to estimate model impact before live deployment.
Strategic Partnership: Act as the scientific consultant for the Presentation Pod, navigating the trade-offs between exploration and exploitation.
Risk Mitigation: Proactively identify and fix potential biases in experimentation pipelines (e.g., selection bias or feedback loops). Mentorship: Provide technical guidance to junior analysts, fostering a culture of scientific rigor.

Basic Qualifications:

Minimum: 5+ years in Data Science; expert knowledge of Causal Inference and counterfactual modeling.

Proficient in Python and SQL

Experience with Contextual Bandits

Additional Qualifications:

Off-Policy Evaluation (OPE); background in high-scale tech or AdTech.
