Affirm is reinventing credit to make it more honest and friendly, giving consumers the flexibility to buy now and pay later without any hidden fees or compounding interest. The Marketplace Experience team sits within Affirm’s Direct-to-Consumer organization and owns the core discovery and evaluation surfaces that help shoppers find the right merchant and financing option for their needs. Our scope includes search, deals, and merchant detail experiences, which are high-traffic, highly visible entry points that directly influence shopper trust, engagement, and downstream conversion. We work at the intersection of consumer experience, merchant strategy, and platform capabilities, partnering closely with Product, Design, Analytics, and dependent platform teams. We are seeking a Staff Software Engineer to provide technical leadership across Marketplace Experience. This is a senior individual contributor role for an engineer who can define and drive long-term technical strategy while remaining deeply hands-on. You will shape the evolution of our systems as we scale the Marketplace to support new discovery paradigms, personalization, and experimentation, while maintaining high standards for performance, reliability, and quality. In this role, you will operate as a force multiplier by setting architectural direction, leading cross-team initiatives, and raising the bar for engineering excellence across the team. You’ll be expected to navigate ambiguity, balance product velocity with technical sustainability, and mentor engineers through example and feedback. If you’re motivated by owning critical customer-facing systems and influencing how teams build and operate software, this role offers broad scope and impact. ##
