[Hiring] Senior Mobile Developer @Your Software Supplier

Role Description

This job is with our partner Micro1.

In this role, you'll apply your expertise to help train next-generation AI systems. Your work will shape how models learn, reason, and perform through high-quality, real-world input.

• Role Type: Contractor (~15 hrs a week)
• Location: Remote

As an expert, you will create Reinforcement Learning Environments that test an AI model’s ability to solve complex mobile software engineering problems related to:

• Fixing code
• Creating features
• Refactoring code
• Optimizing performance

You will be tasked with creating a reproducible environment and a golden reference solution for each problem.

Scope of Work

• 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
  • Improving performance
• Develop tasks relevant to your expertise:
  • Cross-platform applications using TypeScript, JavaScript, or Dart
  • iOS applications using Swift
  • 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.

Qualifications

• Significant hands-on expertise in at least one of the following mobile development tracks:
  • 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.
