Mobile App Developer

About the Role

Build and scale Silvia's mobile application - the primary way independent investors interact with their personal AI CFO on the go. You'll own the native mobile experience end to end, delivering fast, secure, and intuitive financial tools across iOS and Android.

Our values are simple and the lifeblood of our company:

• How you do one thing is how you do everything
• The team you build is the company you build.
• Compete, don't complain.
• Think in decades, act in days.
• Unleash your child-like curiosity.

Our culture is unique, but if you want to build the future alongside other A+ colleagues in a highly entrepreneurial environment, there's no better place to be.

What You'll Do

• Architect, build, and ship Silvia's mobile app end-to-end using React Native/Expo - from architecture to App Store
• Implement real-time financial dashboards, account aggregation views, push notifications, and AI chat interfaces
• Integrate with 10,000+ financial institution connections, financial data APIs, and crypto data providers
• Build secure authentication flows with biometric support (Face ID, fingerprint) and ensure financial data is handled with the highest security standards
• Optimize for performance - smooth scrolling through thousands of transactions, real-time portfolio charts, instant load times
• Share code and patterns with the web team where it makes sense, while ensuring the mobile experience feels truly native
• Collaborate with backend, design, and product to define mobile-specific features and UX patterns

What You Bring

• 7+ years of mobile engineering experience with at least 4+ years building production React Native or Expo apps
• Strong TypeScript skills and comfort working in a shared codebase with web engineers
• Experience shipping apps in regulated or high-trust domains (fintech, healthtech, banking) - you understand what it means when users trust you with sensitive data
• Strong proficiency in React Native, Swift, Kotlin; experience shipping to both App Store and Google Play
• Deep knowledge of mobile-specific concerns: push notifications (APNs/FCM), biometric auth, secure storage, deep linking, and app review processes
• Strong sense of mobile UX - you care about performance, responsiveness, and polish. If something feels slow, you fix it before being asked
• Comfort owning the full mobile lifecycle: architecture, CI/CD, TestFlight/beta distribution, App Store submissions, crash monitoring
• Experience with financial data APIs, OAuth integrations, and real-time data synchronization
• Track record of building high-performance, polished mobile experiences used by thousands of users
• Bonus: Experience with crypto/blockchain integrations (wallet connectivity, on-chain data, token tracking) or real-time financial data visualization on mobile
