Sr. B2B Marketing Manager - Growth (Hybrid @ Bellevue/Seattle (Preferred) / Remote @ California, Texas, Florida

OfferUp for Business gives local businesses and service providers an easy way to reach more customers, build their reputation, and grow their customer base through a vibrant marketplace their community already trusts.

Our team has been building a new self-serve SaaS product to better serve this growing business audience, and it’s almost ready for prime time. We’re looking for a growth-minded B2B marketer who can take a launch and turn it into a lead and revenue engine. You’ll plan, build, and optimize full-funnel campaigns that bring small and medium-sized businesses, service providers, and auto dealerships onto the OfferUp for Business platform—and help them succeed once they’re there.

Your super power? You know how to move seamlessly between strategy and execution: from crafting product positioning and GTM plans to briefing creative, pacing spend, and sharing performance insights, you drive smarter decisions and relentless optimization week over week.

Why this role

• From launch to lift-off: You’ll own go-to-market for OfferUp’s self-serve SaaS offering, working closely with Product, Sales, Ops, and Creative to bring our next growth engine to life.

• Big impact, small team: You’ll get the freedom to experiment, prove what works, and shape how we drive B2B demand at scale.

What you’ll do

• Lead integrated go-to-market planning for OfferUp for Business SaaS products from pre-launch positioning through paid and owned activation

• Run and refine full-funnel campaigns and activations (paid social, search, retargeting, content syndication, field marketing) that drive trials, leads, and conversions

• Build media and creative testing frameworks with the goal of benchmarking and improving CAC:LTV over time

• Design and maintain the B2B attribution model, connecting media spend to lead quality, conversion, and revenue to track performance through the funnel

• Partner collaboratively with Sales, Creative, and Marketing teammates to develop launch materials and sales enablements assets (case studies, pitch decks, FAQs, one-pagers)

• Track competitive landscape, synthesize customer feedback, and apply insights to optimize campaigns, messaging, and collateral

• Report progress through dashboards and concise exec updates that connect effort to ROI

What you bring

• 7–10 years in B2B SaaS or marketplace marketing with hands-on demand gen, performance marketing, and GTM experience

• Proven ability to own a launch and scale it through disciplined experimentation

• Fluency in performance channels (search, social, display, email) and CRM automation

• Strong analytical instincts; you connect spend to outcomes and know how to course-correct fast

• A builder’s mindset that’s most at home working scrappy and fast
