• Integrate with backend APIs, caching layers, and real-time services.
• Debug production issues, investigate edge cases, and ship fixes quickly.
• Implement crash reporting and performance observability (Sentry, tracing, logs, metrics).
• Optimize app performance across rendering, navigation, memory usage, latency, and offline behavior.
• Write clean, maintainable code with a strong understanding of software fundamentals.
• Contribute to technical discussions, planning, documentation, and delivery decisions.
• Support improvements to builds, releases, testing, and app store deployments.

Requirements

• Experience working with native modules and iOS/Android bridging when needed.
• Experience shipping and maintaining apps on the App Store and Google Play.
• Experience with mobile builds, releases, CI/CD, or OTA update flows (EAS, CodePush, or similar).
• Experience with crash reporting and observability tools (e.g., Sentry, performance tracing, logs).
• Strong grasp of software development fundamentals and best practices.
• Ability to debug and fix issues confidently in production.

Nice to Have

• Experience working in startup or high-ownership product teams.
• Experience improving performance, automating releases, or enhancing mobile reliability at scale.
• Familiarity with backend services (Node.js, AWS, Redis, Cloudflare) to enable seamless API integration.
• Experience contributing to or building mobile design systems or shared component libraries.
• Experience with real-time mobile data flows (WebSockets, streaming, event ingestion).
