About the role

  • Develop and iterate native iOS applications using Swift, building modular UI components with SwiftUI while maintaining and refactoring critical flows in UIKit.
  • Architect experimentation-ready solutions using feature flags and A/B testing systems (e.g., LaunchDarkly or internal tools).
  • Leverage AI-native tools (Claude Code, Cursor, GitHub Copilot) to automate repetitive tasks such as unit tests, documentation, and scaffolding experimental features.
  • Manage complex application state using scalable architectures such as RIBs, MVVM+C, or The Composable Architecture, ensuring isolation of experimental features.
  • Integrate with high-performance APIs using GraphQL (Apollo) and REST, maintaining low latency in data-heavy flows.
  • Collaborate with Product and Data Science to define success metrics and instrument experiments using tools like Mixpanel or Segment.
  • Optimize and maintain CI/CD pipelines, enabling fast, confident releases to beta and production environments.
  • Ensure code quality, observability, and long-term maintainability while supporting high-velocity experimentation.

  • Nice to have: Experience working in fintech, payments, or social platforms with high security and performance requirements.
  • Deep understanding of Swift Concurrency (async/await, Actors, structured concurrency).
  • Experience with Snapshot Testing and advanced testing strategies.
  • Knowledge of performance profiling using Instruments (Time Profiler, Leaks, etc.).
  • Experience with on-device ML using CoreML or experimentation with Kotlin Multiplatform (KMP).
