We're hiring a Staff Software Engineer, Native Mobile to join the App Infra team within the Consumer & Business group and help lead Coinbase's greenfield native mobile app rewrite. This team is replacing the existing React Native app with native Swift and Kotlin builds, using AI-driven agentic workflows to translate and rebuild every core surface for millions of customers. Your direction will determine how the team works: you'll bring deep iOS or Android expertise to set the technical bar, own quality outcomes, and translate org strategy into the team's technical execution as product teams onboard to native.

What you'll do:

• Own end-to-end architecture and delivery of core native app surfaces in Swift and Kotlin, operating at depth across the team's codebases and establishing the constrained architecture and compile-time boundaries that enforce strict quality standards.
• Lead the agentic code translation workflow, implementing high-quality automated systems for the team's recurring migration work before asking for headcount, and setting what gets automated versus what stays human across the translation pipeline.
• Own developer experience for the native codebase, accelerating every engineer who onboards by improving build speeds, local development workflows, and CI/CD reliability, and by defining the architectural patterns and documentation that make native mobile development at Coinbase a world-class experience.
• Shape the dual-app agentic synchronization strategy during the transition, prioritizing the highest-impact outcomes and designing the daily agent automations and human review processes that keep native and React Native codebases in sync.
• Become a leader throughout the entire mobile community at Coinbase, defining best practices, mentoring L3-L5 mobile engineers across all teams, and fostering connection and support between all mobile engineers.

Required Skills and Experience:

• 8+ years of iOS or Android mobile software engineering experience (Swift/iOS or Kotlin/Android), with working proficiency in the other platform and willingness to develop cross-platform fluency, as engineers on this team own both iOS and Android.
• Track record of shipping high-quality mobile applications at scale with ownership of architecture decisions, performance budgets, and release quality, with outcomes that would not have happened without your direct involvement.
• Deep understanding of mobile performance optimization, including cold start, frame stability, scroll jank, and time to interaction, with experience profiling and tuning across device tiers including low-end Android.
• Demonstrated ability to translate org strategy into team-level technical execution, build alignment across cross-team and cross-functional partners, and secure commitment on migration timelines and quality standards.
• Experience with AI-assisted code generation or LLM-driven development workflows, with demonstrated judgment on what to automate and what requires human review.
• Experience improving developer experience through build systems, CI/CD pipelines, and release tooling, with improvements adopted beyond your immediate team.
• Uses generative AI responsibly, maintaining human oversight to deliver business-ready outputs and measurable gains in workflow efficiency, cost, and quality.
