Overview
Instacart’s Fraud, Appeasement & Identity (FAI) team protects the marketplace and everyone who depends on it—customers, shoppers, retailers, and brand partners. We build the systems that detect and prevent fraud across payments, accounts, and promotions; ensure that refunds and appeasements are fair, accurate, and resistant to abuse; and verify identity so that every transaction can be trusted. Our mission is to safeguard revenue and customer trust while keeping friction low, so the business can scale with confidence.
We’re looking for a Senior Software Engineer to serve as a technical leader across FAI. In this role, you’ll define the technical strategy and architecture for critical trust surfaces real-time fraud detection, risk decisioning, appeasement and refund-abuse controls, and identity and account-verification workflows. You’ll partner closely with Product, Data Science and ML, Design, Fraud Operations, Legal, and external identity and risk vendors to deliver fast, safe, and scalable solutions.
This is a high-impact role where your work directly influences fraud losses, customer trust, marketplace integrity, and our ability to scale sustainably while meeting regulatory and privacy standards. If you thrive in fast-moving, highly cross-functional environments and enjoy rolling up your sleeves to solve adversarial problems at scale, you’ll feel right at home here. We go far together, communicate with candor, and prioritize solutions where everyone can win.
