Platform Marketing Lead

At Affirm, we exist for the moments that matter—giving people a clear, predictable way to pay over time, with no hidden fees, no surprises, and no tradeoffs on what matters most. About the Team The Revenue team drives Affirm's top-line growth through strategic partnerships, growth initiatives, and go-to-market execution. We acquire, retain, and expand merchant relationships across eCommerce, in-store, telesales, and the Affirm app. The team leads onboarding, relationship management, and performance optimization to help partners succeed. We deliver value-added solutions, drive adoption, and support long-term business growth by connecting merchants and consumers through Affirm's products. Within the Revenue organization, Platform Growth Marketing acquires merchants through platforms and partners. We work with PSPs and ISVs to build joint go-to-market programs, activate partner ecosystems, and drive measurable pipeline, GMV, and revenue. As our partner portfolio grows, we’re building reusable programs, assets, and measurement that help multiple partners go to market at once. The team works closely with Partnerships, Sales, Product Marketing, Brand, Legal, and Revenue Intelligence.

This is a hands-on role. You’ll move between channel strategy, campaign development, partner collaboration, asset creation, execution, and measurement.
