Description

Remote AI project seeking experienced Mobile Software Engineers across iOS, Android, React and Flutter tracks. Engineers create technically challenging coding tasks on real or representative codebases, build reproducible development environments, write deterministic verifiers and develop golden reference solutions. The work evaluates an AI model's ability to debug, refactor and optimize mobile applications.

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

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
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
