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

As Senior Manager, Partner Marketing – Technology Alliances at Klaviyo, you will lead the strategy and execution of partner marketing initiatives that activate our technology ecosystem and drive meaningful business outcomes. This role sits at the intersection of ecosystem strategy, go-to-market execution, and team leadership, with ownership across multiple technology partner initiatives and flagship moments.
