At Klaviyo, we value the unique backgrounds, experiences and perspectives each Klaviyo (we call ourselves Klaviyos) brings to our workplace each and every day. We believe everyone deserves a fair shot at success and appreciate the experiences each person brings beyond the traditional job requirements. If you’re a close but not exact match with the description, we hope you’ll still consider applying. Want to learn more about life at Klaviyo?

About the Team Klaviyo's AI & Analytics pillar is building the intelligence layer behind the product — models that optimize send times, predict churn, surface product recommendations, and power the agentic experiences that help marketers run their business autonomously. With over 200,000+ customers, billions of consumer profiles, and hundreds of billions of messages and conversion events, Klaviyo has the data and scale to build world-class AI and machine learning products. The ML Platform team is the engine that makes all of that possible. Every model that ships at Klaviyo — whether it's predicting the best moment to send an email or powering a Marketing Agent recommendation — runs on infrastructure this team owns. That includes training pipelines (built on Ray), experiment tracking and model registries (MLflow), inference serving infrastructure, feature pipelines, and emerging workflow orchestration tooling (Prefect). As Klaviyo leans harder into agentic products and generative AI, the demands on this infrastructure are accelerating — and so is the team's impact. This PM role is embedded in Palo Alto alongside our ML engineering org. You'll have the kind of proximity to your engineering team that most ML PMs only read about. About the Role We're looking for a Senior Product Manager to own both what Klaviyo's ML models do and the platform that makes building them possible. That's a deliberate pairing: the best ML PM at this stage isn't someone who
