Software Engineer, Frontend (Upfunnel Messaging)

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 Upfunnel Messaging team at Affirm builds and maintains the platform for serving promotional messaging on partner merchant sites and affirm.js, our javascript library for merchant site integration. Our consumer artifacts are heavily used and represent the highest trafficked systems at Affirm; O(10k) merchants use it daily, with O(100M) requests every day.

The goal of the team is two-fold:

1. Improve the consumer experience by surfacing timely, relevant and personalized messaging during their shopping journey.
2. Reduce complexity of merchant integration and improve merchants’ underwriting and monitoring capabilities through high quality tooling and useful, delightful features.

We aim to turn Upfunnel Messaging into a turnkey service, and to empower merchants to optimize and customize all aspects of their messaging strategy, enabling them to grow their business through a data centric approach.
