About The Position

Klaviyo’s platform is built on a foundation of secure, scalable account and identity systems that power every customer interaction. As Klaviyo continues to grow into more complex enterprise use cases and regulated environments, the importance of account integrity, abuse prevention, and flexible organization modeling is critical. This role sits at the intersection of Platform Integrity & Protection area (PAA) and the Accounts teams, partnering closely with Identity & Access Management (IAM), Security, Compliance, and Core Platform teams. Together, these teams define how accounts are created, structured, secured, and governed across Klaviyo. This is a high-impact, cross-functional role responsible for shaping how Klaviyo protects customer accounts and prevents abuse, models accounts and organizations at scale, supports enterprise, compliance, and multi-entity use cases, and builds platform tools that unlock self-serve capabilities and scalable workflows for stakeholders across the entire business. You will serve as the single-threaded product owner across these domains, ensuring that decisions around security, identity, and account structure are made cohesively, not in silos.
