ABOUT THE ROLE 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. RESPONSIBILITIES Buyer Insight as the Foundation for Seller Success - Build a deep, data-informed understanding of buyer behavior on Show: discovery and viewing patterns, what drives watch time and purchase, category and price sensitivity, and trust/loyalty drivers. - Translate buyer insight into a clear point of view on what makes a show, host, or category successful - and use that to define what "good" looks like for brand and enterprise sellers. - Continuously feed buyer-side learnings back into seller-facing strategy, content, and product requirements. Brand and Enterprise Seller Value Proposition and Playbooks - Define the value proposition for brand and enterprise sellers hosting on Show, anchored in demonstrated buyer demand rather than assumptions. - Build and maintain playbooks that help brand and enterprise hosts plan, run, and optimize shows - grounded in what actually drives buyer engagement and conversion. - Partner with Supply/Partnerships and Merchandising to ensure onboarding, enablement, and success materials for brand/enterprise sellers reflect current buyer insight. - Define success metrics for brand/enterprise sellers on Show and identify the levers that most reliably improve them. - Establish comprehensive seller educational programs and trust guidelines that teach enterprise brands how to maintain compliance, protect their reputation, and build long-term buyer loyalty during live broadcasts. Product Narrative, Positioning, and Messaging - Define value propositions and messaging frameworks for buyers and sellers across the Show experience — discovery, live interactions, hosting tools, and checkout. - Develop clear, compelling narratives that translate the mechanics of live shopping into simple, user-centric benefits for both sides of the marketplace. - Ensure consistent storytelling across in-product, lifecycle, marketing, and external channels. GTM Strategy for Launches and Enhancements - Lead GTM strategy for new Show features and enhancements, including: - Feature positioning and differentiation - Target segmentation across buyer segments and host tiers (including brand/enterprise) - Rollout plans, pilots, and experimentation frameworks - Launch KPIs, adoption goals, and success measurement - Partner closely with Product, Growth, and Analytics to execute launches with impact. 6-MONTH ACCOMPLISHMENTS Built a rigorous, buyer-first understanding of Show - Synthesized quali…
