The Card team builds Coinbase's credit and debit card products. We're rebuilding the Card app from React Native to native iOS and Android, and building every new feature natively. We're looking for a senior native engineer to lead that transition: set the architecture and patterns the team will scale on, raise our quality bar to match the best premium consumer apps, and help a team of strong React Native engineers become confident native contributors.

What you’ll do:

Lead the architecture and execution of the Card app's rewrite from React Native to native iOS and Android, including module structure, navigation, state management, design-system integration, and testing.

Define and champion native patterns and standards in Swift/SwiftUI and Kotlin/Jetpack Compose that the team can learn from and scale on.

Build flagship card experiences natively with the polish, performance, and attention to detail of best-in-class consumer apps.

Drive an incremental migration plan so the rewrite lands without stalling feature delivery.

Mentor React Native engineers into confident native contributors through design reviews, pairing, and code review.

Partner with design and product to raise the quality of the experience, not just ship the spec.

Required Skills and Experience:

7+ years building production native mobile apps, with deep expertise in iOS (Swift/SwiftUI) or Android (Kotlin/Jetpack Compose) and strong working knowledge of the other.

A track record of shipping delightful, premium consumer apps known for polish, performance, and craft.

Strong, well-reasoned views on mobile architecture and design patterns, and experience laying out an app structure a team can scale on.

Demonstrated technical leadership: setting standards, driving large migrations or rewrites, and growing other engineers' skills.

Experience partnering closely with design and product on consumer-facing experiences.

Utilizes generative AI responsibly, maintaining human oversight to deliver business-ready outputs and drive measurable improvements in workflow efficiency, cost, and quality.
