Two of our highest-leverage products live at the center of this: Product Recommendations and Audience Optimization. Both are ML-powered. Both exist for one reason: to help brands running autonomous marketing get a real, measurable lift in performance and revenue.</p> <p>Klaviyo runs like an ecosystem of startups. Every team owns real outcomes, and the people who succeed here are builders who pull in the partners they need, even when those partners don't report to them. This role is a clear example of that model in action.</p> <h2><strong>About the Role</strong></h2> <p>We're looking for a Senior Product Manager to own the product and model strategy for two connected feature areas: Product Recommendations and Message Prioritization, with room to take on additional ML-powered feature pods as the portfolio grows.</p> <p>Product Recommendations spans multiple model types, deep familiarity with product catalog data structures, and enterprise-grade customization: filters, guardrails, exclusions, and the business rules brands need layered on top of a model before they'll trust it in production.</p> <p>Message prioritization decides who receives a message, which message they receive, and when. Any given profile might be eligible for several messages in a short window. This feature caps how many they actually get and picks the ones most likely to convert, so the model has to optimize for revenue and conversion at the same time it respects frequency limits.</p> <p>Across both areas, this PM owns the full outcome: not just what ships, but whether it delivers positive lift for the brands using it. That means you're accountable for model performance the same way you're accountable for the product experience wrapped around it.</p> <h2><strong>How You'll Make a Difference</strong></h2> <ul> <li>Own the roadmap for Product Recommendations, including model type selection, catalog data structure decisions, and enterprise-grade customization such as filters, guardrails, and exclusions</li> <li>Own the roadmap for Message Prioritization, defining how the model balances message frequency limits against conversion and revenue outcomes</li> <li>Define what model success looks like for each feature area and build the frameworks to measure lift, conversion improvement, and revenue impact over time</li> <li>Partner closely with ML modeling teams and software engineering teams to translate model capability into features customers actually trust and adopt</li> <li>Design product experiences that make ML-driven decisions understa
