Accountabilities

You will own the development, architecture, and release of high-quality mobile applications, ensuring reliable performance across devices and connectivity conditions. Your responsibilities will include:

Design, develop, and maintain cross-platform iOS and Android applications using React Native, TypeScript, and Expo.

Architect and implement offline-first capabilities, including local data persistence, caching, background synchronization, conflict resolution, and retry/backoff strategies.

Work with local storage and database technologies such as SQLite, MMKV, and WatermelonDB to support dependable field operations.

Lead architectural decisions for new greenfield mobile projects while improving design patterns and maintainability across existing applications.

Use agentic AI development tools to accelerate implementation, carefully reviewing and validating generated code before deployment.

Integrate mobile applications with Supabase, including Postgres, Row-Level Security policies, and Realtime subscriptions, as well as custom production systems and third-party APIs such as HubSpot CRM.

Collaborate with backend engineers and product leads to define efficient data models and type-safe API contracts.

Manage the complete mobile release lifecycle, including provisioning profiles, certificates, build channels, TestFlight, and Google Play Console releases.

Configure and maintain crash monitoring, performance tracing, and release-health telemetry using tools such as Sentry and Firebase Crashlytics.

Investigate issues below the React Native abstraction layer by analyzing native crash logs in Xcode and Android Studio, and developing or modifying native modules when necessary.

Write and maintain unit, component, and end-to-end tests to ensure application reliability and quality.

Requirements

The ideal candidate brings extensive professional mobile engineering experience, strong architectural judgment, and the ability to work independently in a fast-paced, AI-enabled development environment. The following qualifications are required:

At least 7 years of professional mobile development experience, including 4+ years working with React Native in production environments.

Advanced proficiency in TypeScript, React hooks, and modern ES6+ JavaScript.

Experience with state management and data-fetching libraries; TanStack Query is strongly preferred.

Hands-on expertise with Expo across application development, builds, deployment, device management, and release channels.

Proven experience designing and delivering offline-first mobile architectures, including local databases, background synchronization, and data conflict resolution.

Production experience with Supabase or other Postgres-backed platforms, particularly Row-Level Security policies and Realtime subscriptions.

Strong knowledge of native mobile development environments, including Xcode, Android Studio, native crash logs, and App Store and Google Play submissions.

Experience managing application reviews and resolving App Store or Google Play submission rejections.

Demonstrated ability to use AI coding tools effectively while rigorously validating generated code.

Experience writing unit, component, and end-to-end tests using tools such as Vitest, React Testing Library, and Detox.

Excellent written and spoken English, with the ability to contribute actively to technical architecture reviews and product discussions.

Availability for a 40-hour workweek, Monday through Friday, with at least six hours of daily overlap with US Pacific Time business hours and the ability to work until at least 2:00 PM PT. Collaboration with US Eastern Time schedules is also required.

A high-performance macOS development computer capable of running iOS simulators and Android emulators concurrently.

A professional remote workspace with an HD webcam, noise-canceling headset, and enterprise-grade high-speed internet connection.

Additional experience that would be advantageous includes:

Expo Application Services (EAS), Expo Router, expo-updates, over-the-air deployments, and React Native's New Architecture, including Fabric and TurboModules.
