Senior
Own the iOS roadmap for Instacart's shopper checkout, payments, and OCR-driven order-discrepancy experience
This Senior iOS role sits on Instacart's Transaction Platform team, owning the shopper-facing checkout and payments experience plus OCR-based point-of-sale discrepancy detection. It requires deep production Swift (UIKit + SwiftUI, Swift Concurrency, reactive programming) and technical leadership steering iOS strategy, not just executing tickets.
