Android Engineer (Kotlin and Java) Code Review

You will review AI-generated Android code, architecture choices, and technical explanations. You will also write reference implementations, create prompts and model answers, and compare responses for technical quality.

• Review Android code and architecture decisions involving Jetpack Compose, Views, lifecycle behavior, networking, persistence, memory, and performance.
• Evaluate concurrency, coroutines, Flow, threading, cancellation, race conditions, and application-not-responding risks.
• Rate AI responses for correctness, reasoning quality, security, performance, clarity, maintainability, and prompt adherence.
• Write clear reference implementations and step-by-step explanations for complex Android problems.
• Create Android prompts and reference answers to support AI training.
• Identify inaccurate, unsafe, or subtly flawed Android recommendations.
• Check technical content across testing, dependency injection, modularization, CI/CD, and release workflows.

This is an intermediate-level, remote contractor role for Android engineers who want to apply their technical judgment to AI evaluation and training work.

• Time: 20+ hours per week.
• Language: Clear written English is required.
• Experience: Strong production Android experience with Kotlin is required; Java experience is preferred.
• Android knowledge: App lifecycle, Activities and Fragments, state restoration, background execution limits, Jetpack Compose or Views, recomposition, state hoisting, and UI performance.
• Concurrency: Coroutines, Flow, threading practices, cancellation, race-condition prevention, and avoiding application-not-responding issues.
• Architecture and data: MVVM, Clean Architecture, dependency injection, modularization, Retrofit, OkHttp, Room, SQLite, and DataStore.
• Quality and security: Unit, instrumentation, and UI testing; CI/CD and release workflows; secure storage, authentication flows, certificate pinning, and privacy permissions.
