  • We bring the best people, holding high quality standards, and an environment of speed and ambition.
  • You will get to push your boundaries and learn from the best.

    • Results Expected

  • Drive production-quality releases to the App Store weekly, maintaining a ≥98% on-time release rate, zero critical regressions, and ≥99.99% crash-free sessions across all supported iOS versions and devices.
  • Lead performance initiatives across the app, identifying systemic UI, network, and memory optimizations each quarter, with quantifiable improvements in load times, rendering, and responsiveness.
  • Define and enforce testing strategy — ensuring full coverage of logic, UI, and integration flows with zero critical gaps at release.
  • Own and deliver complex, cross-functional mobile features end-to-end — consistently shipping high-impact, high-quality features on schedule, unblocking teams across design, backend, and product.

  • Collaborates fluidly across teams; communicates clearly, with empathy and precision.

    • Technical Competencies

  • Architects and builds scalable, modular iOS systems using Swift, SwiftUI, UIKit, Combine, and modern architecture patterns (MVVM, Clean, VIPER, Composable Architecture).
  • Deeply optimizes performance across cold start, rendering pipelines, concurrency, memory, and network usage — profiling with Instruments and system-level debugging.
  • Shapes technical direction — proactively decomposes legacy systems, establishes reusable design systems, and drives reduction of technical debt with long-term maintainability in mind.
  • Evaluates and introduces new technologies from first principles — selecting frameworks, SDKs, and tools based on measurable impact, stability, and scalability.
  • Owns and evolves CI/CD infrastructure (Xcode Cloud, GitHub Actions, GitLab CI/CD, Bitrise) — enabling parallelized builds, automated testing, and one-tap production deployment.
  • Champions best practices in code quality, testability, accessibility, and security throughout the mobile engineering organization.
