Senior Product Manager, Platform Integrity

About the role

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
• 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.

How You’ll Make a Difference

• 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 IAM 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 (e.g., permissions, lifecycle hooks, settings systems)
• Drive clarity and alignment across stakeholders on tradeoffs between security, usability, and scalability

What You’ll Work On

• Building a unified account model that supports multi-brand, multi-entity customers
• Developing a scalable anti-abuse platform with consistent enforcement across channels
• Improving account lifecycle management, from creation through closure
• Strengthening platform security and risk detection capabilities
• Reducing friction for customers and internal teams through clearer account and org experiences

Who You Are

• You have 5+ years of product management experience, ideally in platform, infrastructure, or security domains
• You have experience working on account systems, identity, permissions, or data models in B2B SaaS
• You are comfortable operating in technical problem spaces and partnering closely with engineering
• You have experience driving cross-team alignment and influencing without direct authority
• You can balance short-term execution with long-term platform strategy
• You are comfortable navigating ambiguity and defining structure in complex environments
• You communicate clearly and can articulate tradeoffs to both technical and non-technical audiences

Nice to Have

• Experience with identity and access management (IAM) systems
• Familiarity with security, compliance, or abuse prevention
• Experience supporting enterprise or regulated environments
• Experience building platform APIs or shared services
• Experience mentoring PMs or leading cross-functional initiatives
