• 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.

• 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.
