· Own mobile features from design through App Store and Play Store releases, ensuring top-notch performance and backend service integration.

· Partner with product and design to transform user needs into mobile experiences that nail both UX and technical constraints.

· Embed with feature teams post-MVP to drive mobile development and mentor engineers on mobile best practices.

· Champion mobile-first thinking across the organization, guiding teams on platform opportunities and limitations.

· 7+ years of professional experience building production mobile apps with proven impact.

· Deep React Native expertise, including navigation (React Navigation), state management (Redux, Zustand, Context), native module integration, and performance optimization.

· Solid TypeScript and modern JavaScript skills, with deep knowledge of React patterns, hooks, component composition, and functional programming.

· Track record of shipping cross-platform mobile apps for iOS and Android, understanding platform-specific nuances.

· GraphQL client integration chops (Apollo Client or similar), including cache management, optimistic updates, and error handling.

· Mobile performance optimization skills: bundle size reduction, faster startup times, memory management, list virtualization, and image optimization.

· Experience with mobile testing frameworks (unit, integration, E2E), crash reporting, analytics integration, and production debugging.

· Understanding of mobile CI/CD, automated builds, code signing, TestFlight/Play Store distribution, and release management.

· Stellar communication and leadership skills, capable of influencing technical decisions and mentoring team members.

· Preferred: fintech background, real-time data integration, complex mobile UI patterns, or native iOS/Android development experience.

· Competitive base salary: $200,000 – $250,000 USD.

· Performance-based bonus eligibility.

· Fully remote work flexibility.

· Health, dental, and vision insurance.
