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 thinks exclusively about model quality or exclusively about infrastructure tooling — it's someone who can reason across both, connecting platform investment to model outcomes and model outcomes to customer impact.
On the modeling side, you'll own the roadmap for Klaviyo's core predictive models — smart send time, audience optimization, product recommendations, and churn prediction — as well as the AI-assisted content and agent capabilities that are growing in importance. You'll define what quality means for each model family, set the evaluation frameworks, and work with ML engineers and data scientists to ensure improvements compound over time.
On the platform side, you'll own the roadmap for the internal infrastructure that every ML team at Klaviyo builds on: DART (our Ray-based offline ML job platform), MLflow, model serving, feature pipelines, and Prefect. Your job is to make Klaviyo's ML engineers faster, safer, and more confident shipping models to production
