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. Affirm, Inc. proudly includes Affirm, PayBright, and Returnly.

Our mission is to take responsibility for the tools, frameworks, and artifacts that empower product teams to seamlessly create and deliver transactional communications to borrowers and merchants. As a dedicated platform team, we are committed to enabling product owners to concentrate on crafting exceptional user experiences, free from the complexities of implementation, transport, and measurement of communications.

We are seeking an experienced Senior Software Engineer to join our dynamic team. In this role, you will play a pivotal part in developing and maintaining a critical messaging service that handles high volumes of emails, SMS, and push notifications. Your expertise will be crucial in ensuring the reliability, scalability, and efficiency of our messaging infrastructure.

We are only just getting started! Come join us as we build a beloved, lasting financial services brand predicated on integrity and trust.

What You'll Do

  • Work with product and engineering managers to identify and plan projects based on the team goals and resources.
  • Consistently generate simple and sophisticated designs and write high-quality code that can be easily understood and used by others.
  • Build relationships with people across engineering and other organizations for the design, implementation, roll-out and maintenance of projects.
  • Drive detailed project definition, design, cross-functional alignment, estimation, in addition to task break-down, delivery, monitoring, and maintenance.

  • Experience with AWS and/or other cloud providers like Azure, GCP etc;.
  • Prior experience in architecting, building, launching and maintaining complex systems.
  • Product-centric thinking -- we care just as much about the product experience — ours, our stakeholders', and our company's — as we do the design of our engineering systems.
  • You are not dogmatic and believe in solving problems with the right tool for the job.
  • Experience providing reviews on teammates code and designs, providing constructive feedback to meet a high bar of quality and help others grow.
  • Well-developed interpersonal, written and verbal communication.
