About The Position

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. Klaviyo’s platform is built on a foundation of secure, scalable account and identity systems that power every customer interaction. As we continue 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 hybrid role that requires 3 days/week in our SF office. We’re hiring a Senior Product Manager to own the end-to-end strategy across Platform Integrity & Protection (PAA) and Accounts. 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.
