Marketing Manager, Paid Acquisition (Hybrid @ Bellevue, WA)

About OfferUp OfferUp believes all value starts local. Our marketplace makes it easier for people and businesses to find more of what they need, right where they are—from great deals and secondhand finds to local services, rentals, jobs, and new customers. We’re building the next chapter of OfferUp, and Consumer Marketing has an important job to do: create future demand, capture existing demand efficiently, reactivate people who already know us, and connect our investment to our strongest local marketplaces. The role We’re looking for a hands-on paid acquisition marketer to own the day-to-day operation of our consumer media channels across Meta, Google and YouTube, TikTok, Snap, and emerging paid tests. This is a role for someone who can build and QA a campaign themselves, spot a performance shift before it becomes a problem, and explain what changed without hiding behind a dashboard. You’ll turn our broader growth strategy into clean, consistent execution: media planning, campaign setup, trafficking, pacing, optimization, platform QA, testing, troubleshooting, and weekly channel diagnostics. The sweet spot is someone who can live inside the platforms without getting trapped at platform altitude—operationally rigorous, analytically sharp, and always aware of the role each channel plays in the larger growth system. What you’ll do Own daily and weekly paid-channel operations across Meta, Google/YouTube, TikTok, Snap, and new platform tests. Translate growth strategy and budget allocations into executable media plans by channel, market tier, objective, audience, and campaign type. Build, traffic, and maintain campaigns, including targeting, bidding, budgets, naming conventions, UTMs, placements, creative mapping, and launch QA. Monitor and optimize performance across CPI, CPM, CTR, CVR, install volume, reach, frequency, geo performance, and creative fatigue. Deliver first-pass channel diagnostics: what changed, why we believe it changed, and what action should follow. Keep budgets pacing cleanly and surface risks, opportunities, and material variances early. Design disciplined tests across creative, audience, geography, placement, bidding strategy, and campaign objective. Partner with creative and growth leads to traffic new assets quickly and translate performance signals into useful creative feedback. Manage relationships with platform partners, troubleshoot account and delivery issues, and stay current on meaningful platform changes. Maintain clear campaign documentation and operating standards so our work is consistent, auditable, and easier to learn from. Contribute to weekly performance reporting and make clear recommendations about what to scale, adjust, pause, or investigate. What you’ll bring 8+ years of hands-on paid acquisition, performance marketing, or media-buying experience, ideally for a consumer app, paid media agency, or digital marketplace.
