Senior Mobile Developer

Micro Ai is hiring a Senior Mobile Software Engineer (contract, ~15 hrs/week) to help build reinforcement learning environments and deterministic verification tasks for training AI models on complex mobile software engineering challenges.

Responsibilities

• Create realistic, interesting, and extremely challenging mobile coding tasks for frontier AI models using repositories you prefer.
• Design problems that require strong mobile engineering skills, including subtle bug discovery, non-trivial feature development, application state and lifecycle handling, and performance improvements.
• For each task, define the problem statement, build a reproducible environment, and implement deterministic verifiers that:
  • Accept correct solutions across different valid implementations
  • Reject incorrect, incomplete, or hard-coded approaches
• Deliver a golden reference solution that demonstrates how the task can be solved.

Requirements

• Significant hands-on expertise in at least one mobile development track:
  • Cross-platform: TypeScript 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.

Technologies

• TypeScript, JavaScript, React Native
• Dart, Flutter
• Swift, SwiftUI, UIKit
• Kotlin, Jetpack Compose, Android View system

Scope of Work

• Develop realistic, interesting, and extremely challenging mobile coding tasks for frontier AI models using your preferred repositories.
• Create tasks that test strong mobile engineering capabilities, including subtle bug tracking, non-trivial features, state and lifecycle management, and performance work.
• Develop tasks aligned to your expertise:
  • Cross-platform applications using TypeScript, JavaScript, or Dart
  • iOS applications using Swift
  • Android applications using Kotlin
• Define the problem, build a reproducible environment, and write deterministic verifiers that generalize across valid solutions while rejecting incorrect or hard-coded attempts.
• Provide a reference solution that shows how the task can be solved.

Benefits
