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 Communications Platform team is responsible for Affirm’s consumer messaging systems. We provide a scalable, fault-tolerant abstraction on-top of messaging vendors that enable teams to focus on their core product experience. Our stakeholders rely on us to process billions of messages across SMS, Email and Push with strict regulatory and deliverability constraints.

Affirm is growing rapidly and so is the need for reliable, highly available platform capabilities. As a Senior Software Engineer on this team, you’ll help define the next evolution of our platform. If solving challenges at scale excites you, come join us!

What You’ll Do

  • Drive project planning, system design, cross-functional alignment, in addition to delivery, monitoring, and continuous iteration
  • Consistently generate simple and elegant designs, write high-quality, testable, peer-reviewed code which will be a model for the team
  • Adhere to and advocate for engineering best practices across the team, such as robust automated testing and observability
