About The Position

The Profiles Platform team at Klaviyo owns the core customer data system, which serves as the foundation for every product experience across the platform. This team is responsible for storing, managing, and serving customer profile data as the source of truth for downstream products such as segmentation, flows, reporting, and analytics, ensuring data accuracy, scalability, and usability. Their work is critical for making Klaviyo’s platform intelligent and reliable at scale, covering areas from data modeling and computed properties to enterprise-scale ingestion and global compliance. Klaviyo is seeking a Senior Product Manager to define the strategy and roadmap for this Profiles Platform. This role involves structuring, processing, and serving customer profile data, operating at the intersection of data infrastructure, computed data, and scalability. The Senior Product Manager will ensure profile data remains trustworthy and performant as Klaviyo expands into more complex enterprise and global use cases. This is a high-impact platform role that directly influences nearly every product team and customer experience. This is a hybrid role requiring 3 days/week in the Boston office, and fully remote candidates will not be considered.
