• Integrate mobile applications with backend REST APIs, implementing offline-first behavior, local persistence, and reliable data synchronization.
• Own the mobile release process end to end (build pipelines, code signing, provisioning profiles, submissions to App Store Connect and Google Play Console, and beta distribution and staged rollouts via TestFlight and Play Console release tracks), working with our DevOps team to ensure all processes are automated and repeatable.
• Instrument applications for crash reporting, performance monitoring, and usage analytics; diagnose and resolve platform-specific issues including memory pressure, threading and concurrency defects, battery consumption, and device fragmentation.
• Conduct comprehensive testing, debugging, and code reviews; collaborate with Quality Assurance to ensure software quality across the supported device matrix, and participate in incident response and root cause analysis for mobile-related issues.
• Provide technical leadership and mentorship to the development team while collaborating with product, architecture, and scrum teams to scope work, provide accurate estimates, translate business needs into technical solutions, document architecture and release procedures, demo functionality during Sprint Review, and stay current on emerging mobile technologies, platform releases, and store policy changes.
