About you Strong development experience in Swift and a solid understanding of the iOS SDK , including UIKit, SwiftUI, and Combine.

Experience building features that support recommendations, discovery, search, or personalization is a strong plus. Comfortable working with data-driven features , understanding how to capture and leverage signals to improve user experience. You write clean, maintainable code with a focus on testing, reliability, and scalability.

Have worked on marketplace consumer apps: recommendation engines, feeds, or AI-driven personalization in a consumer app. Have experience with analytics, feature flags, or experimentation frameworks on mobile. Have contributed to high-traffic, data-heavy apps where performance and scalability are critical.
