Responsibilities

Lead the design, development, and delivery of high-quality React Native applications that are scalable, secure, maintainable, and optimized for performance across iOS and Android.
Define and apply modern mobile architecture patterns, reusable component approaches, testing practices, and coding standards that improve quality, consistency, and developer productivity.
Use your experience in native iOS and/or Android development to guide platform-specific design decisions, integrate native capabilities, and resolve complex technical issues when React Native alone is not sufficient.
Help build and strengthen our development team by mentoring engineers, supporting hiring and technical evaluation, conducting code reviews, and coaching others on React Native best practices.
Foster a strong community of React Native developers by sharing knowledge, improving team practices, contributing to standards, and helping create an environment of continuous learning and technical excellence.
