• Establish strong observability practices, including crash reporting, structured logging, analytics, feature flags, and A/B experimentation.

• Lead architecture design reviews and RFCs, providing technical direction and long-term scalability guidance.

• Mentor engineers, conduct code reviews, and drive knowledge-sharing across the mobile engineering team.

• Collaborate closely with product, design, backend, and QA teams to deliver high-quality mobile experiences.

• 5–6 years of professional experience in mobile application development, with strong expertise in React Native.

• Deep understanding of React Native architecture, rendering pipeline, and performance characteristics.

• Strong proficiency in TypeScript, modern JavaScript, and React fundamentals.

• Hands-on experience with state management solutions, navigation libraries, and modular application design.

• Proven experience working with native modules, including Bridges, TurboModules, and JSI.

• Strong understanding of mobile performance optimization, profiling tools, and debugging techniques on iOS and Android.

• Experience setting up and maintaining mobile CI/CD pipelines, including build automation and release workflows.

• Solid understanding of app distribution, code signing, build variants, and OTA update mechanisms.

• Ability to take ownership of features and systems from design through production.

• Strong communication skills and experience working in cross-functional teams.**Desired Skills -**

• Experience with CodePush or similar OTA update solutions.

• Familiarity with mobile analytics, experimentation frameworks, and feature flag systems.

• Exposure to monorepo setups and shared codebases across web and mobile.

• Experience contributing to or maintaining internal mobile libraries or design systems.

• Understanding of Agile development methodologies and iterative delivery.

• Best in class compensation: We hire only the best, and we pay accordingly.

• Proximity Talks: Learn from experienced engineers, designers, and product leaders across the organization.

• Work with a world-class team: Build scalable mobile products, push technical boundaries, and learn something new every day.
