Android Engineer (Kotlin and Java)

Skills

About this role

As an Android Engineer (Kotlin / Java), you will work remotely on an hourly paid basis to review AI-generated Android code, mobile architectures, and technical explanations, as well as produce high-quality reference implementations and step-by-step reasoning for complex engineering problems. You will assess solutions for correctness, clarity, security, performance, reliability, and adherence to the prompt; identify issues in Jetpack Compose/UI, concurrency, threading, memory/performance, app lifecycle, networking, persistence, and build/release practices; fact-check technical information; write high-quality explanations and model solutions; and rate and compare multiple AI responses.

Android, Kotlin, Jetpack Compose

Responsibilities

• Develop AI Training Content: Create detailed prompts across Android topics and write high-quality reference answers to guide AI learning.
• Optimize AI Performance: Evaluate and rank AI responses to enhance correctness, security, performance, and maintainability.
• Ensure Model Integrity: Test AI outputs for inaccuracies or unsafe recommendations, validating reliability across real-world Android use cases.

Qualifications

• Bachelor's degree or higher in Computer Science, Software Engineering, or a closely related technical field.
• 4+ years of professional experience building production Android apps, including work in Kotlin and (ideally) Java codebases.
• Expert-level proficiency in Kotlin (Kotlin 1.6+): null-safety, coroutines/flows, sealed types, generics, and idiomatic patterns.
• Strong Android fundamentals: app lifecycle, Activities/Fragments, state restoration, background execution limits, and permissions.
• Modern UI experience with Jetpack Compose and/or Views; ability to reason about recomposition, state hoisting, and UI performance.
