  • Ability to independently diagnose common React Native production issues such as rendering, navigation, networking, and lifecycle problems.
  • Track record of owning mobile initiatives from requirements through store release, including related backend and web frontend changes.
  • Experience designing mobile application architecture with performance, reliability, and observability trade-offs across iOS and Android.
  • Experience designing or integrating native modules and SDKs, including Swift/Kotlin changes and debugging across JavaScript and native layers.
  • Experience owning the release process, including app signing, store submission, and staged rollouts.
  • Experience establishing mobile engineering practices such as standards, CI/CD, and release processes across inherited and greenfield codebases.
  • Experience designing resilient asynchronous and event-driven backend interactions, such as messaging and queues.
  • Experience with mobile production operations, including monitoring, crash reporting, incident response, and rollback policy.
  • Demonstrated ability to mentor and develop less experienced engineers.
  • English proficiency sufficient for daily written and verbal communication.
  • Fluent in Russian and English at B2 level.
