Analyst II, Full Stack (Core Analytics)

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.

We’re looking for a driven, analytically-minded professional to join the Core Analytics team within the Risk & Analytics organization! Our team improves the developer experience across Affirm by building scalable data infrastructure, streamlining workflows, and fostering a culture of learning and documentation. This role sits at the intersection of data and engineering, while staying focused on turning developer workflows and system reliability into clear, actionable signals that accelerate delivery.

We take ownership of the entire analytical lifecycle, from initial question to final business decision, ensuring Affirm grows efficiently and intelligently.

The ideal candidate will have strong technical and problem-solving skills, an eagerness to collaborate with different teams, curiosity to learn more every day, and patience to work through difficult problems.
