Senior Software Engineer, Backend (Repayment UX)

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 over 15 million 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!

What You'll Do

• Contribute to the design and implementation of large scale and low latency services, elegant abstractions, shareable libraries, and robust APIs.
• Influence strategic and tactical decisions related to our product, platform and success metrics.
• Identify stakeholders, gather their needs and opinions, advocate for ideas and initiatives, and create a common understanding where all voices are heard.
• Partner with engineers, other engineering teams and third-party vendors to develop reliable and scalable solutions to a wide range of problems.
• Collaborate with cross-functional partners like product managers, designers and analysts to deliver an outstanding, high quality experience to our users. The vast majority of people you’ll interact with day to day are located in a compatible timezone.
• Lead and mentor engineers to help them succeed and grow. Provide them with the right context and train them to take ownership of their respective pieces of our initiatives.
• Review others’ work and provide reinforcing and constructive feedback to meet our high quality standards.
• Write high-quality code that can be easily understood and leveraged by others.
• Rigorously test the code we write as a team and support it as part of a sustainable on-call rotation.
