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 Repayment UX Engineering team is growing and looking for a Senior Software Engineer specializing in Backend development. We’re a full-stack engineering team located entirely in Poland. We build and own user flows that enable tens of millions of consumers to repay loans worth over $20B each year. We continuously innovate to make the flow more user-friendly, more effective, and adapt to the needs of our rapidly expanding business. Our work is agile and fast-paced, shipping new code to production almost every two-week sprint, and rigorously measuring the impact it has on the behavior of our users.

This role requires a high level of technical capability, strong cross-functional communication, and a creative mindset. There’s a very high degree of ownership in the role: you will know precisely what your objectives are, you’ll get everything you need to achieve those objectives, and you’ll be free to choose your own path to reach them. You’ll have the opportunity to share your knowledge with others, and learn from very experienced teammates and collaborators. Come join us!
