Role Title: Senior Mobile Software Engineer
Role Type: Contractor (~15 hrs a week)
Location: Remote
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.
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, and 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, or improving performance.
- Develop tasks relevant to your expertise: cross-platform applications using TypeScript, 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.
Preferred 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.
Compensation Structure
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.
Start Timeline & Availability
- We typically fill roles within 48 hours and are looking for experts ready to jump in right away. If selected, we expect you to start your first tasks within 24-48 hours of completing onboarding.

Pay and terms
The listing does not state a rate for this role. It describes pay this way: output-based, paid per approved task. micro1's expert guide describes pay in bands by type of work rather than per role, so treat any figure you see elsewhere as unconfirmed until it appears in your contract.
micro1 engages experts as contractors. Its help library says payments are made in USD twice a month and that contracts and payroll run through Deel. Payments cannot be processed until identity verification there is complete. Read our micro1 review for what workers say about project availability and support.
Before you apply
Engineering listings usually ask for years of professional experience, and some ask for a public code history such as open-source commits. Have your profile or repositories ready to link.
Applying starts with an AI interview, then certification, then matching to projects by recruiters. micro1 says certification does not guarantee a project, so treat this as flexible work and not as a job offer. The how to become an AI trainer guide walks through each step.
