About the Role

We are looking for an experienced React Native Developer to join our team and help build high-quality mobile applications. The ideal candidate has strong expertise in modern React Native development, including the New Architecture, and is passionate about delivering scalable, performant, and user-focused mobile experiences.
 

You will work in a remote-first environment, collaborating closely with product, design, and engineering teams to deliver features quickly while maintaining high standards of code quality and reliability.
 

Requirements

Experience & Expertise

• Proven experience with React Native for mobile app development, including the New Architecture (Fabric, JSI, TurboModules).
• Strong portfolio demonstrating development of complex, large-scale apps.
• In-depth understanding of client-server architectures with RESTful APIs.
• Experience with Expo and the managed/bare workflow ecosystem.
• Familiarity with multimedia processing (audio/video handling) is a plus.
   

Technical Skills

• Proficient in TypeScript and modern front-end technologies.
• Experience with state management (Redux Toolkit, Zustand, or similar) and navigation frameworks (React Navigation, Expo Router).
• Knowledge of native module integration and performance optimization, including profiling with Hermes and identifying render bottlenecks.
• Performs meaningful unit and integration tests. Experience with Jest and React Native Testing Library is a plus.
   

AI-Assisted Development

• Actively uses AI coding tools (e.g., Cursor, Claude) to accelerate development.
• Critically reviews and tests AI-generated code before committing.

Delivery Speed

• Demonstrates a bias toward shipping: breaks work into small, reviewable increments and moves features from spec to working code quickly.
• Comfortable making pragmatic tradeoffs; knows when “good enough now” beats “perfect later.”

Communication & Collaboration

• Strong written English; comfortable in async, remote-first environments.
• Proactively surfaces blockers: communicates problems clearly and early, proposes solutions or asks a specific question. Never goes silent on a problem for hours.
• Experience in agile environments; comfortable with short feedback loops and scope changes.

Additional Attributes

• Problem-solving mindset with attention to detail and code quality.
• Self-directed and organized; manages priorities without needing close supervision.
• Proficient with Git, including branching strategies and code review practices.
