Engineering Manager, Integrations

Team Overview

The Integrations team is responsible for building and maintaining Klaviyo’s integrations to a variety of 3rd party vendors. These vendors can be grouped across a number of industries such as ecommerce, point of sale, payment processing, advertising, and fundraising. In order to enable our customers to integrate with these different vendors we provide easy-to-use interfaces that guide our customers through the setup and management of an integration. Behind the scenes, we use a variety of pipelines to process data flowing to and from these vendors at a petabyte scale. We collaborate closely with internal stakeholders and have substantial exposure to Klaviyo's customers, including businesses, partners, and third-party developers.

How you’ll make an impact

The Integrations team operates at the intersection of distributed systems, software architecture, data mapping & pipelining, scalability, and reliability. As an Engineer Manager, you will own and drive the technical vision of our existing integrations as well as help build new integrations across various verticals in a fast, flexible, efficient, and maintainable way, resulting in world class customer and developer experiences. Critical components of the Integrations space include Klaviyo’s V3 APIs, 3rd party vendor’s APIs, inbound and outbound data pipelines, and data mapping and transformation. You will have an opportunity to learn our existing end-to-end integration workflow and help scale it up to support the next evolution of Klaivyo’s growth into several verticals. You’ll work closely with a team of talented software engineers, data scientists, product managers, and UX/UI designers who are eager to make the process of integrating with Klaviyo fast, efficient, and seamless. Your technical leadership, outside-the-box thinking, and execution will help shape Klaviyo’s trajectory for the next decade.
