Senior Software Engineer, Back-end, (Repayment Scheduling)

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.

The Repayment Scheduling engineering team is growing rapidly, and we're looking for a Senior Software Engineer specializing in Backend development. We're a Backend team located entirely in Europe within the same time zone, but culturally rooted in Silicon Valley. We build and own the system that enables our users to automate their payments, at a scale of up to $40B each year. We directly own the configuration and orchestration of those payments. We directly improve the financial lives of over 20 million people, giving them peace of mind that their payments will be made on time.

Our work is agile and fast-paced, shipping new code to production every two-week sprint, and rigorously measuring the impact it has on our users' lives and company financials. This role rewards curiosity, ownership, and a builder's mindset. You'll know exactly what your objectives are, you'll have what you need to hit them, and you'll choose your own path to get there. You'll learn quickly from experienced teammates and grow your craft on problems that matter at scale.
