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 Ledger Engineering team maintains Affirm’s financial source of truth through the loans ledger system. We design and operate critical accounting infrastructure that tracks all financial events from authorization through settlement. Our team maintains core ledger systems that serve as Affirm’s financial backbone, runs daily processing pipelines with strict SLAs, ensures data integrity for financial reporting, audits, and compliance, creates ETLs that deliver reconciled accounting data to downstream teams, and supports cross-functional financial modeling and accounting needs. We work closely with Finance, Accounting, Capital Markets, and other engineering teams to ensure accuracy in Affirm’s financial systems.
