Mobile Developer

About the Role

We are seeking experienced Mobile Software Engineers 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.

Key Responsibilities

• 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.

Requirements & Tech Stack

• 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.

Qualifications

Relevant backgrounds include:

• Mobile Software Engineers
• Mobile Application Developers
• Senior Mobile Engineers
• Mobile App Developers
• Mobile Platform Engineers
• iOS Engineers, iOS Developers, Swift Developers, SwiftUI Developers, UIKit Developers, and Apple Platform Engineers.
• Android Engineers, Android Developers, Kotlin Developers, Jetpack Compose Developers, and Android Application Engineers.
• React Developers, React Engineers, Flutter Developers, Flutter Engineers, Dart Developers, and Cross-Platform Mobile Engineers.
• Frontend Engineers, Full-Stack Engineers, Product Engineers, and Software Developers with substantial production mobile application experience.
• Mobile Architects, Staff Mobile Engineers, Principal Mobile Engineers, Mobile SDK Engineers, and Application Performance Engineers.

Preferred Background

• Professional experience with TypeScript or JavaScript and React.
• 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.
