• Partner closely with Product, Design, Backend Engineering, Data, and leadership

• Build polished, fast, reliable, consumer-facing mobile experiences

• Improve app performance, stability, navigation, rendering, networking, error handling, and release quality

• Help shape mobile product strategy and future iOS team development

Must Have

• 5+ years of production iOS engineering experience

• Strong Swift experience

• Experience with SwiftUI, UIKit, or modern iOS architecture patterns

• Experience building high-quality consumer-facing mobile applications

• Ability to own or heavily influence architecture decisions for an iOS codebase

• Strong product sense and attention to mobile UX, performance, polish, and edge cases

• CS degree or strong computer science fundamentals

• Experience with top-tier consumer products, engineering-driven companies, or elite startup environments

• Interest in helping build and mentor a future mobile engineering team
