  • Demonstrated ability to build and ship performant mobile applications with a focus on frame stability, cold start optimization, and responsive UI across diverse device populations.
  • Proficiency in Swift or Kotlin with working knowledge of the other, and willingness to develop cross-platform fluency, as engineers on this team own both iOS and Android.
  • Experience with mobile CI/CD pipelines, build systems, and release processes, with a track record of delivering project-level outcomes that compound beyond the immediate cycle.
  • Uses generative AI responsibly, maintaining human oversight to deliver business-ready outputs and measurable gains in workflow efficiency, cost, and quality.
