Sr. Partner Marketing Technology Alliances Manager

Are you passionate about building ecosystems and turning partnerships into real, measurable growth?

As Sr. Partner Marketing Technology Alliances Manager at Klaviyo, you’ll play a critical role in activating our technology partner ecosystem through joint marketing, joint demand generation, and high-impact partner moments. You’ll work closely with ecommerce platforms, ISVs, and technology partners to bring integrated solutions to market and accelerate adoption of the Klaviyo platform.

You’ll collaborate with a wide range of technology partners across the commerce ecosystem — including leading platforms and ISVs such as Shopify, WooCommerce, TikTok, Google, and others — to bring integrated solutions to market and create meaningful value for shared customers.

This role sits at the intersection of partner marketing, ecosystem activation, and go-to-market execution. You’ll design and execute co-marketing programs that help technology partners show up meaningfully across Klaviyo’s ecosystem — from the App Marketplace to flagship global events like K:Boston, K:Sydney, and K:London.

You’ll collaborate closely with Partnerships, Field Marketing, Events, Product Marketing, and Sales to ensure partner marketing initiatives are aligned with business priorities and deliver tangible outcomes. Your work will directly influence partner-led demand, product adoption, and Klaviyo’s growth across the commerce technology ecosystem.

This is a highly visible role for a forward-thinking, hands‑on marketer who thrives in fast‑paced environments and knows how to turn partnerships into scalable growth engines.
