Sr. Product Manager - Self-Hosted Ecomm Integrations

At Klaviyo, Product Managers have mastered the craft of product management. They are highly skilled practitioners who have driven significant business outcomes, and they thrive in a high-growth environment that offers unlimited potential. As a Senior Product Manager, you’ll not only be responsible for delivering impact through your own work, but you’ll also mentor the next generation of product leaders. Please note that this is a hybrid role that requires 3 days/week in our Boston office. Fully remote candidates will not be considered at this time.

About the Team:

Klaviyo’s Data Infrastructure pillar is responsible for maintaining a centralized, scalable data store with flexible, low-latency reads for all of an organization’s customer and related data. As part of this team, you’ll play a critical role in ensuring our integrations empower merchants to grow faster and connect seamlessly across systems.

This role focuses on owning the product strategy, execution, and business results for Klaviyo’s first-party integrations with self-hosted eCommerce platforms — specifically Magento 2, Salesforce Commerce Cloud (SFCC), WooCommerce, and PrestaShop. You’ll build enterprise-grade, reliable integrations that directly impact revenue, upmarket growth, and merchant success.

Senior Product Managers at Klaviyo are measured by the outcomes they drive. In this role you’ll:

• Deliver business impact by setting and executing a roadmap that advances our integrations and drives measurable results.


• Champion customer needs by spending significant time with merchants and partners, building a deep understanding of their workflows and challenges.


• Think deeply and analytically to break down complex problems, explore multiple solutions, and ensure every edge case is addressed.


• Communicate exceptionally well in writing and verbally, ensuring clarity across all stakeholders.


• Lead by example as a mentor and coach, raising the bar for other PMs on the team.

What You’ll Do:

• Collaborate across product, engineering, research, design, sales, partnerships, and external stakeholders to deliver high-impact outcomes.


• Own and prioritize the roadmap for self-hosted integrations, focusing on the projects with the greatest business impact.


• Write detailed specifications that anticipate use cases, solve problems elegantly, and leave no ambiguity.


• Ship features quickly and iteratively, getting value into customers’ hands while continuing to improve.


• Mentor other product managers, sharing your experience and raising the overall standard of product excellence.


• Continuously learn and dive deep into new areas, becoming an expert in self-hosted eCommerce platforms and extensibility.

Who You Are:

• 5-7+ years of product management experience, ideally with technical products or infrastructure.


• Proven track record of owning products end-to-end and delivering measurable business outcomes.


• Strong technical expertise in system integrations (REST APIs, webhooks, authentication, data pipelines, cloud architecture).


• Experience with products where extensibility is a core requirement, enabling customization and integrations across ecosystems.


• Background working with enterprise/upmarket merchants, mapping technical and business requirements across multi-system environments.


• Experience collaborating with external partners and aligning on joint strategic priorities.


• Passionate about building B2B SaaS products, with a hustler mindset, resourcefulness, and bias toward action.


• Exceptional written and verbal communication skills.

Nice to Have:

• Familiarity with extensions and plugins, especially in the eCommerce space.


• Experience with internationalization and how it affects integrations and content.
