About this role

Role Overview

The Senior Staff Data Scientist - Consumer Experimentation position at Reddit is a senior technical leadership role focused on solving complex causal inference and experimentation challenges across the Consumer organization. This remote, United States-based position suits an expert statistician or quantitative researcher who wants to shape product strategy and experimentation rigor at a massive digital scale.

Key Responsibilities

Act as the main technical authority on experimentation methodology for the Consumer organization, setting rigorous standards for design and analysis.
Tackle advanced experimentation problems such as network interference, spillover effects, two-sided experimentation, and long-run effect estimation.
Create and improve causal inference methods in situations where standard assumptions fail, utilizing cluster-randomized designs, switchback experiments, and synthetic control strategies.
Design experimentation frameworks and guardrail metrics to measure true causal impact rather than biased local estimates.
Build and scale self-serve experimentation tools, platforms, and best-practice documentation to elevate experimentation velocity and literacy.
Influence long-term product strategy by turning experimental results into clear, actionable recommendations for senior company leadership.
Mentor other data scientists on experimentation best practices, causal reasoning, and advanced statistical rigor.

Requirements

Ph.D. in Statistics, Econometrics, Economics, Computer Science, or a related quantitative field with a strong focus on causal inference or experimentation methodology, along with 8+ years of industry experience; OR an M.S. degree with 12+ years of industry experience in applied science, data science, or experimentation roles.
Deep expertise in causal inference, including practical work with network interference, switchback designs, cluster randomization, or synthetic control methods.
Strong theoretical grounding in experimental design, power analysis, variance reduction, sequential testing, and multiple comparison corrections.
Direct experience building or significantly extending internal experimentation platforms at scale.
Expert knowledge of SQL and professional proficiency in R and/or Python for statistical computing.
Demonstrated ability to influence product strategy and translate ambiguous, complex technical problems into structured solutions.
Excellent communication skills tailored for technical and non-technical senior stakeholders.

Nice to Have

Published research or industry contributions regarding network experimentation, interference in experiments, or marketplace causal inference.
Familiarity with Bayesian experimental methods, adaptive experimental designs, or bandit algorithms.
Prior experience working with user-generated content platforms or social networks with complex community-level dynamics.
