The team owns our Credit Card, Debit Card, payments, cash, and loyalty products (Coinbase One), along with our onchain products for borrowing and lending.</p> </div> <div class="md-block"> <p>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.</p> </div> <p><strong>What you’ll do:&nbsp;</strong></p> <ul> <li>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.</li> <li>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.</li> <li>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.</li> <li>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.</li> </ul> <p><strong>Required skills and experience:</strong></p> <ul> <li>5+ years of iOS or Android software engineering experience in Swift or Kotlin.</li> <li>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.</li> <li>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.</li> <li>A strong point of view on design and user experience, with real investment in product polish and interaction detail.</li> <li>Responsible use of generative AI: human oversight on AI-generated output, with measurable gains in workflow efficiency, cost, and quality.</li> </ul> <p>P77525</p> <p>#LI-Remote</p><div class="content-pay-transparency"><div class="pay-input"><div class="description"><p><strong>Pay Transparency Notice:</strong><strong><em> </em></strong>Base salary varies by location (see range below).
