Salary: $190,000 – $240,000/yr
Type: Full-time
This role is ideal for a seasoned backend engineer with at least 5 years of experience who enjoys building the "connective tissue" between a major fintech platform and its enterprise partners. You should be highly proficient in either **Python or Kotlin** and have a solid grasp of distributed systems using AWS, MySQL, and Kubernetes. This is a "builder" role focused on the full API lifecycle—from initial design to high-stakes maintenance. The compensation is a major highlight, reaching up to **$240k base**, plus equity and a fully remote-first culture. Affirm offers exceptional benefits, including **100% company-paid medical premiums** for you and your family, and unique monthly stipends (Flexible Spending Wallets) for tech, food, and lifestyle needs. It’s a stable yet fast-paced environment where you’ll have significant ownership over how enterprise merchants integrate with the service. **You might be a good fit if you:** * Have 5+ years of experience and can confidently navigate and debug large, complex codebases. * Excel at translating vague business requirements into scalable, well-tested technical solutions. * Are comfortable with "keep the lights on" responsibilities, including metrics monitoring and on-call rotations. * Prioritize clear communication and enjoy collaborating with product and design teams in a remote setting.
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 Partner Merchant Interface (PMI) team builds the APIs and solutions that powers Affirm’s integrations with Enterprise Merchants and Partners.
