Full job description

Are you a Kotlin expert eager to shape the future of AI? Large-scale language models are evolving from chatbots into powerful developer assistants capable of reasoning about complex software systems. With high-quality engineering data, tomorrow's AI can support developers in solving real-world problems faster and more accurately. That training data begins with you—your coding expertise will help power the next generation of AI.

We're looking for Kotlin specialists who can take real-world engineering scenarios—such as bug reports or feature requests in a Git repository—and produce clean, efficient, and idiomatic solutions using the Kotlin programming language. You'll create high-quality code patches that reflect modern Android development practices and ensure technical correctness, maintainability, and clarity.

You should have hands-on experience with modern Android and Kotlin development, including Jetpack Compose, Kotlin Coroutines, and Jetpack libraries such as Room, WorkManager, Datastore, ViewModel, and Hilt. Familiarity with build.gradle configuration, dependency management, and networking libraries such as OkHttp, Retrofit, and Coil is also important. Experience with Android multimedia tools (CameraX, ExoPlayer, Media3) is a plus.

On a typical day, you'll evaluate AI-generated code, correct errors, implement optimized Kotlin solutions, and document best practices that demonstrate modern Android design patterns and coding conventions.

A strong background in Android software development is required, with demonstrable experience building and maintaining production-level Kotlin applications. Clear, structured communication and the ability to explain technical decisions are essential.

We offer a pay range of $35+ per hour, with the exact rate determined after evaluating your experience, expertise, and geographic location. Final offer amounts may vary from the pay range listed above. As a contractor, you'll supply a secure computer and high-speed internet; company-sponsored benefits such as health insurance and PTO do not apply.
