Job description

Mobile Software Engineers, iOS, Android & Cross-Platform Developers. Remote AI Project

We are seeking experienced Mobile Software Engineers, iOS Developers, Android Developers, React Engineers, and Flutter Developers to contribute to a remote AI project focused on advanced mobile software engineering.

You will create challenging coding environments that test an AI model’s ability to debug mobile applications, build non-trivial features, refactor complex code, manage application state and lifecycle, and optimize performance.

What You’ll Do

• Create realistic and technically challenging mobile software engineering tasks using real or representative codebases.
• Design problems involving bug fixing, feature development, application state, lifecycle behavior, asynchronous workflows, refactoring, and performance optimization.
• Build tasks for React, Flutter, iOS, or Android applications based on your expertise.
• Create reproducible development environments that allow each task to be evaluated consistently.
• Write deterministic verifiers and automated checks that recognize correct solutions while rejecting incomplete, incorrect, or hard-coded implementations.
• Develop golden reference solutions demonstrating one valid way to solve each engineering problem.
• Identify edge cases and ensure tasks require genuine mobile engineering reasoning rather than superficial code changes.
• Document task requirements, expected behavior, verification logic, and implementation assumptions clearly.

Who Can Apply

Relevant backgrounds include Mobile Software Engineers, Mobile Application Developers, Senior Mobile Engineers, Mobile App Developers, and Mobile Platform Engineers.

We also welcome iOS Engineers, iOS Developers, Swift Developers, SwiftUI Developers, UIKit Developers, and Apple Platform Engineers.

Android backgrounds may include Android Engineers, Android Developers, Kotlin Developers, Jetpack Compose Developers, and Android Application Engineers.

Cross-platform backgrounds may include React Developers, React Engineers, Flutter Developers, Flutter Engineers, Dart Developers, and Cross-Platform Mobile Engineers.

Software engineering backgrounds may include Frontend Engineers, Full-Stack Engineers, Product Engineers, and Software Developers with substantial production mobile application experience.

Additional relevant backgrounds include Mobile Architects, Staff Mobile Engineers, Principal Mobile Engineers, Mobile SDK Engineers, and Application Performance Engineers.

Requirements

• Significant professional experience building mobile applications.
• Strong hands-on expertise in at least one mobile development track: React, Flutter, iOS, or Android.
• Deep understanding of mobile architecture, state management, asynchronous programming, and application lifecycle.
• Strong debugging and problem-solving skills across complex mobile codebases.
• Experience building non-trivial application features.
• Ability to refactor code while preserving functionality and improving maintainability.
• Experience identifying and resolving mobile application performance issues.
• Strong understanding of software testing and automated verification.
• Ability to communicate technical requirements and reasoning clearly.
• Comfortable working independently in a remote environment.

Preferred Background

• Professional experience with Dart and Flutter.
• Professional experience with Swift, SwiftUI, or UIKit.
• Professional experience with Kotlin, Jetpack Compose, or Android Views.
• Experience designing complex coding exercises, interview problems, benchmarks, or engineering assessments.
• Experience creating reproducible development environments and automated test suites.
• Experience with mobile CI/CD, build systems, release pipelines, or platform tooling.
• Experience working in large or mature mobile codebases.

This opportunity is ideal for experienced mobile engineers who can look at a real application, identify subtle bugs or architectural problems, design challenging engineering tasks around them, create reliable automated verification, and provide a clean reference solution that demonstrates strong mobile engineering judgment.
