Key Responsibilities Lead and support a team of mobile engineers building React Native applications across iOS and Android. Remain deeply hands-on in development, contributing directly to architecture, implementation, code reviews, debugging, and releases. Partner with product, design, and other engineering teams to deliver high-quality mobile experiences aligned with business priorities. Help establish scalable mobile engineering practices including component patterns, testing strategies, release processes, and code quality standards.
