In this hourly, remote contractor role, you will serve as the Kotlin Quality Assurance Lead, responsible for ensuring quality, consistency, and trainer performance across Kotlin AI training projects. You will review AI-generated Kotlin code and evaluate the output quality against project guidelines, providing precise written feedback and ensuring adherence to expected standards. Your assessments will cover code correctness, type safety, coroutine behavior, Android/JVM awareness, debugging accuracy, readability, maintainability, performance, security, test coverage, formatting, instruction-following, and rubric adherence. This role is part of a rapidly growing AI Data Services company that delivers training data for some of the world's largest AI companies and foundation-model labs. Your leadership in Kotlin quality will help guarantee that training data is accurate, executable, idiomatic, clearly explained, and aligned with client expectations. The selection process includes an AI interview, a domain-specific task, and an interview with a recruiter. Please note that there is no immediate project for this role; however, if qualified, you will be among the first experts we contact when relevant opportunities arise, granting you access to future projects available through our expert network.
