Senior Product Manager, ML Signals

Details

Reddit is a community of communities. It’s built on shared interests, passion, and trust, and is home to the most open and authentic conversations on the internet. Every day, Reddit users submit, vote, and comment on the topics they care most about. With 100,000+ active communities and approximately 126 million daily active unique visitors, Reddit is one of the internet’s largest sources of information.

As a Senior Product Manager for ML Signals, you will define and execute the team roadmap by partnering closely with ML Signals Machine Learning Engineers, other surface consumer product managers, data scientists, and policy experts. With a strong background in the latest ML/AI research, you will lead the expansion of content understanding signals across all modalities, including text, image, and video, to support a unified multimodal representation of Reddit content. You will define the goals and success metrics, identify initiatives to achieve the goals and collaborate with cross functional partners to deliver these initiatives. You will be able to prioritize projects by what will have the most downstream impact and help drive adoption of these signals across the org.

Responsibilities

• Signal Strategy & Vision: Define the long-term roadmap for foundational "content understanding" signals, including topicality (interest-based tagging), content maturity, and quality scores used across the platform.
• Platform Adoption: Act as the primary bridge between the MLE team and downstream consumers (e.g., Feed, Ads, Search, and Safety). Drive the integration of ML signals to improve personalization and brand safety.
• Signal Governance: Establish standardized definitions and success metrics for content quality and utility, ensuring a consistent understanding of "high quality" across different product surfaces.
• Data Strategy & Labeling: Lead the strategy for high-quality training data, including the use of "Human-in-the-Loop" (HITL) workflows and modern automated evaluation techniques (e.g., using Large Language Models to assist in data labeling).
• Performance Optimization: Partner with Data Science and MLEs to monitor signal health, coverage, and accuracy (Precision/Recall), and translate technical performance into business impact (e.g., retention, engagement, or revenue).
• Cross-Functional Leadership: Navigate complex tradeoffs between Policy, Engineering, and Product teams to ensure signals meet both user safety requirements and product growth goals.
