ThredUp is transforming the way people buy and sell secondhand fashion. As a mission-driven company, we're passionate about inspiring a new generation of conscious consumers and we need a smart, resourceful marketer who can meet the business wherever it needs them.

We're looking for a Swiss Army knife: someone who brings deep marketing craft to whatever challenge is in front of them, whether that's building a product launch GTM plan, standing up a seller nurture email campaign, putting on a growth and performance marketing hat, running customer research, or digging into data to understand behavioral patterns. You'll be the voice of the seller and a key driver of supply growth, but the work will shift with the business, and you'll need to shift with it.

You'll partner closely with Product, Revenue, Merchandising, and Brand. As our founding PMM, you'll also help define how product marketing supports both seller and buyer initiatives over time.

In This Role You'll Get To:

Own the Seller Growth Mandate

• Diagnose the seller funnel end-to-end and identify the highest-leverage opportunities whether that's a messaging overhaul, a new lifecycle program, or a feature launch.
• Move fluidly between strategic and executional work: one week you might be building a GTM plan for a new seller feature, the next you might be standing up a supply nurture email campaign or running research to understand why sellers lapse.
• Define seller segmentation, positioning, and messaging, then work closely with channel owners to make sure those strategies land.
• Guide CRM, paid, and organic channel owners to develop seller-focused campaigns and lifecycle programs tied to supply goals.
• Partner with Brand Marketing to integrate seller stories into broader brand moments.

Turn Data and Insights into Action

• Run qualitative and quantitative research to understand seller behavior, inform positioning, and surface lifecycle opportunities.
• Dig into performance data to understand what's working, where sellers are dropping off, and what to test next across channels, creative, messaging
• Maintain a competitive picture of supply-side experiences; translate findings into risks, opportunities, and prioritized tests.

Bring New Seller Features to Market

• Partner with Product to shape feature direction with clear, seller-oriented value props; lead naming, packaging, launch tiering, and GTM plans.
• Support copy and creative development for concept and message testing.
• Orchestrate cross-functional readiness product experience, notification strategies, measurement to ensure a high-quality seller experience at launch and beyond.

Build the PMM Function

• Establish ways of working with Product, Merchandising, and Marketing; set standards for briefs, launch tiers, and measurement
• Own and drive strategic marketing initiatives and special projects as business priorities evolve

What We're Looking For:

• 7+ years in product marketing, growth & performance marketing within consumer marketplaces or e-commerce with genuine breadth across the marketing mix.
• Channel fluency: you understand how CRM, paid, organic, and in-product channels work and how to connect them to business outcomes. You may not be a specialist in all of them, but you're not intimidated by any of them.
• Revenue orientation: you think in terms of business impact, connect your work to metrics that matter (CAC, supply volume, repeat rate, conversion), and can size opportunities before investing in them.
• Analytical chops: comfortable pulling and interpreting data, designing research, and using both to prioritize and pivot.
• Positioning and messaging fluency: you know how to build a clear value prop from customer insight and translate it into crisp, channel-ready communication.
• Adaptive mentality: you thrive when the work shifts with the business, you're not precious about your lane, and you move fast without losing rigor.
• Builder's mindset: you've taken something from 0-1, you're comfortable in ambiguity, and you're excited about defining how PMM works here.
• Supply-side marketplace experience (e.g., driver, seller, host) is a strong plus.
