Klaviyo is seeking a Senior Product Manager to own end-to-end strategy for Platform Integrity & Protection (PAA) and Accounts. This is a high-impact, cross-functional role responsible for shaping how Klaviyo protects customer accounts, prevents abuse, models accounts and organizations at scale, and supports enterprise and compliance use cases.
You will serve as the single-threaded product owner across identity, access management, and account systems, ensuring decisions around security and account structure are made cohesively. Key responsibilities include:
• Own and drive product strategy and roadmap across Platform Integrity & Protection and Accounts
• Define and evolve Klaviyo's account and organization model to support enterprise scale and complexity
• Lead initiatives focused on account security, authentication abuse prevention, and risk mitigation
• Partner deeply with Identity & Access Management teams to align authentication, authorization, and identity systems with account modeling
• Collaborate with Security, Compliance, Legal, and GTM teams to meet regulatory and enterprise requirements
• Align multiple engineering teams around shared data models, platform capabilities, and security posture
• Define and track metrics for account security, abuse prevention, and platform health
• Enable other product teams by building shared frameworks (permissions, lifecycle hooks, settings systems)
• Drive clarity and alignment across stakeholders on tradeoffs between security, usability, and scalability
You will work on building a unified account model supporting multi-brand and multi-entity customers, developing a scalable anti-abuse platform with consistent enforcement across channels, improving account lifecycle management, strengthening platform security and risk detection, and reducing friction for customers and internal teams.
Required: 5+ years of product management experience, ideally in platform, infrastructure, or security domains. Experience with account systems, identity, permissions, or data models in B2B SaaS. Comfort operating in technical problem spaces and partnering closely with engineering. Experience driving cross-team alignment and influencing without direct authority. Ability to balance short-term execution with long-term platform strategy. Comfort navigating ambiguity and defining structure in complex environments. Clear communication skills for both technical and non-technical audiences.
Nice to have: IAM systems experience, familiarity with security/compliance/abuse prevention, experience supporting enterprise or regulated environments, experience building platform APIs or shared services, experience mentoring PMs or leading cross-functional initiatives.
Note: This role requires 5 days/week in the Boston office.
