About this role, in micro1's words
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.
What you'll do
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.

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.
Working with micro1Pay, getting started and work, from micro1's own pages
What the platform publishes in general. These are not extra terms confirmed for this particular role.
- Getting paid
- Paid in US dollars twice a month through Deel, usually landing around the 5th and the 20th. Nothing is paid until Deel's identity check is done. library.micro1.ai/working/faqs, library.micro1.ai/working/payroll-policy
- Before your first paid task
- An AI interview with micro1's recruiter Zara, then your profile, ID verification, a KarmaCheck background check and the Deel contract. Some pipelines add a quiz or test task. micro1.ai/experts, micro1.ai/ai-interview-guide, library.micro1.ai/getting-started/next-steps-after-certif..., library.micro1.ai/working/faqs, library.micro1.ai/working/what-to-expect
- How much work
- Certification makes you eligible but does not guarantee placement. micro1's FAQ puts the usual commitment at about 15 to 20 hours a week, depending on the client. micro1.ai/experts, library.micro1.ai/working/faqs
- Contract
- Independent contractor, with the contract issued through Deel. library.micro1.ai/policies/understanding-your-expert-agre..., library.micro1.ai/working/deel

Alex's experience on micro1A personal account, not a promise about your project
Alexruns this site and has worked on micro1 himself. Written 31 Aug 2026.
- Every interview I took used an AI interviewer, and some included a timed business exercise of around 25 minutes.
- On later applications, interview reuse on micro1 was often partial, and I still answered questions about one to three additional skills.
- I entered a requested rate for the job. One listing showed about $180 an hour. I requested about $160 and received the rate I entered. Those amounts are approximate, and this describes my application, not proof that a lower request caused acceptance.
- Onboarding and setup came to about 2 hours, with clear materials. Of the three platforms I worked on, it was the easiest transition into work. That is an estimate from my projects, not a platform average.
- On my micro1 project, Hubstaff showed time and mouse or keyboard activity, not screenshots, app names or website history. That describes what I saw, not every possible setup.
- I was paid for hours logged, once every 14 days, and I have not experienced late or incorrect payments. That was my arrangement.

Platforms sometimes change a rate after posting. Every listing here is re-read at least once a day and corrected when its source moves, so a difference you see on the platform is usually a change made since the last read. How freshness works.
