Senior Mobile Developer

• Create realistic, interesting, and extremely challenging mobile coding tasks for frontier AI models using your preferred repositories
• Design problems that require strong mobile engineering skills, such as tracking down subtle bugs, building non-trivial features, handling application state and lifecycle, or improving performance
• Develop tasks relevant to your expertise: cross-platform applications using Type Script, JavaScript, or Dart; iOS applications using Swift; or Android applications using Kotlin
• For each task, define the problem, build a reproducible environment, and write deterministic verifiers that accept correct solutions across different valid implementations while rejecting incorrect, incomplete, or hard-coded approaches
• Provide a reference solution showing how the task can be solved

• Significant hands-on expertise in at least one of the following mobile development tracks:
• Cross-platform:
  Type Script or JavaScript with React Native, or Dart with Flutter
• iOS:
  Swift with SwiftUI or UIKit
• Android:
  Kotlin with Jetpack Compose or the Android View system
• Deep understanding of mobile application architecture, state management, asynchronous programming, and application lifecycle
• Proven ability to debug complex mobile applications, resolve bugs, and deliver effective performance improvements

Compensation is output-based; experts are paid per task that meets the project specifications. The time required to complete work may vary depending on the expert s experience and workflow. Minimum weekly submission requirements apply and will be communicated during onboarding.
