Software Engineer II - Editors

Why You Should Join the Editors Team :

The Editors team is responsible for building common reusable components for the message editor. This team powers all the editors at Klaviyo. This team focuses on building intuitive and powerful interfaces to create highly customizable and dynamic content ranging from product feeds, real time event data, and more. This product area is core to Klaviyo’s continued success.

As a Software Engineer II on the team, you’ll play a key role in designing and building scalable systems that power our editor experiences across all the editors. Partnering closely with product managers and technical product owners, you’ll help define scope, translate ideas into practical implementations, and build intuitive editing tools that delight our users. This role leans frontend, with a strong focus on crafting thoughtful, reusable components and seamless user experiences using technologies like TypeScript, React, Python, and Django. There are ample opportunities for growth given the scope of this role and the team’s central role in Klaviyo’s product.

Over the past year, our team has enhanced the editor interfaces with impactful features that our customers love—and they’re eager to see that same power brought to other mobile experiences. Looking ahead, we’ll be investing in new editor blocks, a personalization builder, in-canvas editing, and content generation powered by AI. You’ll contribute directly to these efforts, helping Klaviyo extend its best-in-class editing tools across platforms.
