About the job

5 min read13 sections

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 UX Engineering team is growing, and we're looking for a Senior Software Engineer specializing in React Native development. We're a full-stack team located entirely in Europe within the same time zone, but culturally rooted in Silicon Valley. We directly improve the financial lives of over 20 million people. We build and own user journeys that enable them to pay back loans worth collectively over $40B each year. Our team exists to make these moments the most reliable and transparent in world-class consumer finance.

Our work is agile and fast-paced, shipping new code to production every two-week sprint, and rigorously measuring the impact it has on the behavior of our users. 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.

If you want to build something new and operate it at scale – come join us!

You write high quality code that is easily understood and used by others. · You are proficient at making significant changes in a large code base, and have developed a suite of tools and practices that enable you and your team to do so safely. · Your experience demonstrates that you take ownership of your growth, proactively seeking feedback from your team, your manager, and your stakeholders. · You have strong verbal and written communication skills that support effective collaboration with our global engineering team.
