Senior Mobile Developer

$50–$100/h

Remote

Role overview

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

  1. Create realistic, interesting, and extremely challenging mobile coding tasks for frontier AI models using your preferred repositories.
  2. 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.
  3. Develop tasks relevant to your expertise: cross-platform applications using TypeScript, JavaScript, or Dart; iOS applications using Swift; or Android applications using Kotlin.
  4. 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.
  5. Provide a reference solution showing how the task can be solved.

Preferred Qualifications

  1. Significant hands-on expertise in at least one of the following mobile development tracks:
  2. Cross-platform: TypeScript or JavaScript with React Native, or Dart with Flutter.
  3. iOS: Swift with SwiftUI or UIKit.
  4. Android: Kotlin with Jetpack Compose or the Android View system.
  5. Deep understanding of mobile application architecture, state management, asynchronous programming, and application lifecycle.
  6. 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

  1. 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.

How big is the remote / hybrid opportunity?

Remote work is already huge — but the bigger story may be the hundreds of millions of jobs that could still move beyond geography.

Global remote and hybrid work opportunity infographic

Remote work already connects millions of people with companies they would never have been able to work for a decade ago. But compared with the size of the global labour market, it may still be early.

The interesting number is not only how many people work remotely today — it is how many roles could plausibly become remote or hybrid next.

The chart above starts with roughly 3.3 billion people employed worldwide. Around 300 million jobs are already remote or hybrid, while an additional pool of roughly 250 million roles could potentially move in that direction as technology, workflows and company culture continue to change.

Skills are becoming more portable

This matters because more work can increasingly be matched to expertise rather than location. AI training and evaluation are a good example: companies need lawyers, engineers, designers, editors, researchers, finance professionals and many other specialists to help improve AI systems.

For workers, that creates access to projects outside their local market. For companies, it expands the talent pool from one city or country to the world.
