Reddit is seeking a Senior Director of Consumer Data Science to lead a multi-team organization that partners across Consumer, Product, Engineering, and the broader business. You will set the strategy and operating model for consumer data science, strengthen the systems and standards that make scientific outputs reliable, actionable, and scalable, and guide high-impact decisions through measurement, experimentation, causal inference, and ML.

This leader will help define how Reddit measures and improves relevance across the consumer journey—from retrieval and ranking to feed, search, recommendations, and community discovery—and will shape the organizational capabilities required to advance these systems over the long term. Accordingly, the role requires the technical depth to evaluate architecture and analytical investments, guide state-of-the-art ML system improvements, and the leadership presence to align senior leaders around difficult tradeoffs.

What you’ll do

• Partner with senior leaders across Consumer, Product, Engineering, and business functions to define company-level bets, priorities, and tradeoffs.
• Set the data science strategy for Reddit’s feed, recommendation, search, retrieval, and ranking systems, including objective design, candidate generation, ranking quality, relevance evaluation, experimentation, and long-term optimization.
• Establish the measurement and experimentation framework for relevance optimization, including offline evaluation, online experimentation, counterfactual analysis, guardrail metrics, metric integrity, and the connection between model improvements and consumer and community outcomes.
• Translate complex user and community behavior into clear, impartial insights that improve product strategy and consumer outcomes.
• Establish durable standards for measurement, experimentation, causal inference, reproducibility, privacy, responsible AI use, and self-serve measurement, at scale.
• Build multi-team roadmaps, operating cadences, and clear accountability that turn company direction into durable delivery.
• Exercise strong technical judgment across architecture choices, analytical systems, hiring, and sponsorship of high-leverage programs.
• Build or rebuild systems and practices that make analytical work reliable, adoptable, and scalable rather than dependent on individual heroics.
• Recruit, retain, and develop exceptional Directors, managers, and IC5+ leaders across multiple teams or pillars.
• Set a high talent bar through succession planning, calibration, and clear expectations for coaching, performance, accountability, and growth.
• Create durable cross-org forums and operating mechanisms that improve coordination, culture, and decision quality.
• Align senior product, engineering, and business leaders on measurement strategy, difficult tradeoffs, and decisions with material multi-year impact.
• Represent Reddit externally and internally as an acknowledged thought leader and visible culture shaper for rigor.
• Partner with teams advancing ML and analytical systems that deepen understanding of Reddit’s UGC and community ecosystem.

Skills and Qualifications

• Deep data science expertise in measurement, experimentation, causal inference, ML, data platforms, and analytical systems, with the technical judgment to set company-scale standards.
• Experience in UGC or community ecosystems and a strong point of view on how data science can improve consumer experiences while protecting analytical quality, privacy, and responsible AI practices.
• Proven ability to connect model and system improvements to consumer value, content quality, trust, diversity, healthy participation, and long-term business outcomes—not only short-term engagement metrics.
• Senior leadership experience leading multi-team or multi-pillar organizations and delivering attributable business impact through durable roadmaps, operating mechanisms, and long-range bets.
• Proven organization builder with a track record of recruiting and retaining exceptional senior leaders, developing Directors and managers, and creating a healthy, high-trust leadership bench.
• Exceptional communication and influence with experience aligning senior product, engineering, and business leaders; resolving conflict; and communicating uncertainty, risks, and tradeoffs with intellectual honesty.
