Sr. Manager, Product Marketing (Posh Live)

The Sr. Manager, Product Marketing (Posh Live) sits at the intersection of Product, Growth, Community, and Content, working closely with the Director of Product Marketing and the GM of Posh Live. This role defines how Posh Live shows up to buyers and sellers - shaping positioning, messaging, and go-to-market strategies that drive adoption, engagement, and growth for Poshmark's live shopping product. Critically, this role starts from the buyer. You will build a deep, first-hand understanding of why and how buyers discover, watch, and purchase through live shows, and use that understanding to define what it takes for a brand or enterprise seller to actually succeed on Show. Seller-facing value propositions, enablement content, and playbooks should all be grounded in real buyer behavior and demand - not written from the seller side in. This role is both strategic and highly hands-on, with day-to-day cross-functional execution.
