Ideal candidates have hands-on experience across mobile stacks, strong debugging skills, and a track record of building non-trivial features.

Qualifications

• 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.

• 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.
