We're hiring a native mobile engineer to join Coinbase's Financial Services and Loyalty product group. The team owns our Credit Card, Debit Card, payments, cash, and loyalty products (Coinbase One), along with our onchain products for borrowing and lending. This role sits at the center of a significant transition: the product group is moving from React Native to native Swift and Kotlin in a greenfield app rewrite. That rewrite is built inside an AI-assisted code generation workflow, with the goal of delivering a dramatically faster, higher-quality experience to millions of users. As an engineer on this team, you'll bring deep iOS or Android expertise to the core foundation of the new native app — setting design and development standards and acting as a technical leader for the broader organization. What you’ll do: Own the development of core app surfaces in Swift and Kotlin, translating existing React Native flows into performant native implementations that meet strict performance budgets, and setting the project-level quality bar through code and design reviews. Work within the AI-assisted code generation loop, using LLMs as a force multiplier for translation while applying native mobile judgment to validate architecture, catch edge cases, and ensure production-quality output. Act as a mobile community lead within the business unit: contributing to engineering onboarding, reviewing pull requests, challenging suboptimal patterns, and fixing slow paths the team has learned to live with — flaky tests, painful deploys, ambiguous handoffs between the native and React Native codebases. Support the product group's dual-app parity strategy during the transition, identifying and removing the technical debt that matters while keeping features and bug fixes synchronized across both codebases. Required skills and experience: 5+ years of iOS or Android software engineering experience in Swift or Kotlin. A track record of building and shipping performant mobile applications, with attention to frame stability, cold start optimization, and responsive UI across a diverse device population. Proficiency in Swift or Kotlin with working knowledge of the other, and genuine willingness to build cross-platform fluency — engineers on this team own both iOS and Android. A strong point of view on design and user experience, with real investment in product polish and interaction detail. Responsible use of generative AI: human oversight on AI-generated output, with measurable gains in workflow efficiency, cost, and quality.
