• Participate in technical discussions to align development work with business objectives.
• Communicate effectively across distributed teams.

Architecture & Design

• Design and implement scalable application architecture for React Native mobile apps with a focus on maintainability, performance, and developer experience.
• Lead architectural decisions around shared code strategies between React web and React Native mobile platforms.
• Establish and enforce coding standards, design patterns, and best practices across the mobile development team.
• Create technical specifications and architecture documentation for complex features and systems.
• Build and maintain a robust monorepo infrastructure using tools like Nx, Turborepo, or similar.
• Configure and optimize build pipelines, dependency management, and workspace configurations.
• Implement efficient caching strategies and incremental builds to optimize CI/CD performance.
• Manage versioning, publishing, and dependency relationships between packages.
• Design and develop a comprehensive shared component library that works seamlessly across React and React Native.
• Create platform-agnostic business logic, utilities, and services that can be consumed by both web and mobile.
• Build tooling and documentation to enable other developers to easily leverage shared code.
• Implement adaptive components with platform-specific implementations where necessary while maintaining a unified API.
• Establish patterns for sharing type definitions, hooks, contexts, and state management across platforms.

Qualifications & Skills:

• 5+ years of experience in mobile application development with a strong focus on React Native.
• Bachelor's degree in Computer Science, Engineering, or a related field (or equivalent experience).
• Proven track record of delivering commercial mobile applications from concept to launch.
• Proficiency in React Native and JavaScript/TypeScript, with knowledge of native modules (Swift/Kotlin) as a plus.
• Strong understanding of mobile architecture patterns and state management.
• Experience with third-party integrations and APIs.
