Remote Android Engineer (Kotlin/Java) – AI Code Reviewer

SME Careers; Singapore; A distancia; SGD 55.000 - 110.000; Jornada completa

Descripción de la vacante

SME Careers is seeking an experienced Android Engineer (Kotlin/Java) for a fully remote, hourly contractor role. You will review AI-generated Android code, architectures, and explanations, and produce high-quality reference implementations with step-by-step reasoning for complex engineering problems.

You will assess solutions for correctness, performance, security, and reliability, addressing Jetpack Compose/UI, concurrency, memory, and build/release practices, while providing clear technical

Formación

• Bachelor’s degree in Computer Science, Software Engineering, or a closely related technical field (or equivalent practical experience).
• 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.
• Concurrency expertise: coroutines, Flow, threading best practices, cancellation, and avoiding race conditions/ANRs.
• Strong knowledge of architecture patterns: MVVM, Clean Architecture concepts, dependency injection (Hilt/Dagger/Koin), and modularization.
• Experience with networking and data: Retrofit/OkHttp, serialization, caching, offline strategies, and persistence (Room/SQLite/DataStore).
• Experience with testing and quality: JUnit, instrumentation tests, Compose UI tests/Espresso, mocking strategies, CI/CD (Gradle, Play Console workflow).
• Security awareness: secure storage (Keystore/EncryptedSharedPreferences), auth flows, certificate pinning awareness, privacy permissions, and sensitive data handling.
• Minimum C1 English proficiency (written and spoken), with the ability to write clear technical explanations and follow detailed English-language guidelines.
• Previous experience with AI data training, annotation, or evaluating AI-generated technical content is a strong plus.
• Highly detail-oriented and systematic, with a methodical approach to evaluating reasoning quality and identifying subtle issues in complex Android code.

Responsabilidades

• 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.
