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. As we build Affirm's advertising platform and evolve Marketplace into a best in class shopping destination, the ability to route and discover is one of the greatest levers for consumer experiences. Search is one of the highest impact surfaces, and we are building a new team that will own not just the recommendations and search experiences, but also explore opportunities to improve customer experience, monetization, and merchant value. This team will help make Affirm the definitive destination consumers turn to for discovery, understanding, comparing, and shopping through Affirm, and will also lay the foundation for an agentic platform.

You write high quality code that is easily understood and used by others. · You thrive in ambiguity, and are comfortable moving from low level language idioms all the way to the architecture of large systems to understand how they work. · Your growth and impact trajectory demonstrates that you have mastered gathering and iterating on feedback from your engineering and cross-functional peers. · You have strong verbal and written communication skills that support effective collaboration with our global engineering team. · This position requires either equivalent practical experience or a Bachelor’s degree in a related field.
