    Mindrift connects specialists with project-based AI opportunities for leading tech companies, focused on testing, evaluating, and improving AI systems. Participation is project-based, not permanent employment.

    What This Opportunity Involves

    While each project involves unique tasks, contributors may:

    • Design and maintain automated tests to ensure the quality, performance, and reliability of Kotlin and Android applications.
    • Collaborate with developers to identify, reproduce, and resolve functional, performance, and UI issues across multiple environments.
    • Define and improve quality standards across build pipelines, ensuring smooth CI/CD integrations and release stability.
    • Monitor app behavior in production and use data‑driven insights to guide testing priorities and improvements.
    • Apply professional judgment to assess AI responses

    What We Look For

    This opportunity is a good fit for Senior Kotlin software developers open to part-time, non-permanent projects. Ideally, contributors will have:

    • Degree in Computer Science, Software Engineering or related fields
    • 5+ years of Kotlin including coroutines, extension functions, and sealed classes.
    • 3+ years of Android/JVM development experience
    • Familiarity with JUnit 5, Kotest, MockK, and Android testing (Espresso, Robolectric).
    • English proficiency - B2
    • Stable internet connection

    How It Works

    Apply → Pass qualification(s) → Join a project → Complete tasks → Get paid

    Project time expectations

    Tasks for this project are estimated to take 6-10 hours to complete, depending on complexity. This is an estimate and not a schedule requirement; you choose when and how to work. Tasks must be submitted by the deadline and meet the listed acceptance criteria to be accepted.

    Payment

    • Paid contributions, with rates up to $80/hour*
    • Fixed project rate or individual rates, depending on the project
    • Some projects include incentive payments
    • Note: Rates vary based on expertise, skills assessment, location, project needs, and other factors. Higher rates may be offered to highly specialized experts. Lower rates may apply during onboarding or non-core project phases. Payment details are shared per project
