About the Team

This is a newly formed team responsible for data ingestion into Klaviyo’s core data objects. The team sits at a critical junction between our various integration teams and the core data platform, acting as the interface that ensures data flows cleanly, reliably, and at scale into foundational systems.

As Klaviyo continues to scale, the quality, reliability, and architecture of our ingestion systems are increasingly critical to product performance and customer trust. This team will define the next generation of how data enters and powers our platform.

About the Role

We are seeking a highly technical Senior Product Manager to lead the strategy and execution for our Data Ingestion Platform. This is a traditional platform PM role, ideal for someone comfortable operating in deep architectural discussions and experienced with large-scale data movement and distributed systems.

You will define the vision and roadmap for how large volumes of data from diverse sources are ingested, transformed, and made reliable within Klaviyo’s core systems. You’ll work closely with engineering, integration teams, and downstream stakeholders to modernize legacy pipelines and build a scalable, unified ingestion framework. This role requires strong product leadership, comfort with ambiguity, and the ability to operate at both strategic and highly technical levels. This is a hybrid role that requires 3 days/week in our Boston office. Fully remote candidates will not be considered at this time. 

Why This Role Matters

Data is foundational to everything Klaviyo delivers. This role sits at the heart of how that data enters and powers the platform. You’ll shape the architecture that enables reliable, scalable data ingestion for years to come, driving platform health, reducing complexity, and unlocking innovation across the company.

If you’re energized by building structure where it doesn’t yet exist, modernizing complex systems, and operating at the intersection of data architecture and product strategy, this is a high-impact opportunity to define a critical platform capability at scale.

What You’ll Do:

• Define the long-term mission, charter, and ownership boundaries for a newly formed team.


• Develop and maintain a coherent, high-impact roadmap that balances foundational investments with active initiatives.


• Refine prioritization and sequencing across multiple concurrent projects to ensure focus on the highest-value work.


• Own the strategy and roadmap for ingesting large volumes of data from numerous sources.


• Think holistically about data movement, transformation, and reliability at scale.


• Partner with engineering to design ingestion systems that are scalable, resilient, and maintainable.


• Navigate tradeoffs across performance, latency, cost, and reliability.


• Drive improvements in observability, monitoring, and operational excellence for ingestion systems.


• Identify and drive architectural simplifications that improve platform health over time.

What You Bring:

• Strong experience as a Platform Product Manager, ideally in data infrastructure or distributed systems environments.


• Deep understanding of data architecture and large-scale systems.


• Experience working with event-driven systems, high-volume ingestion pipelines, or complex data movement patterns.


• Comfortable engaging in highly technical discussions around pipelines, infrastructure, and system evolution.


• Proven ability to define structure and clarity in ambiguous, newly forming teams.


• Skilled at stakeholder management across multiple technical organizations.


• Able to think strategically while managing highly technical execution details.
