About The Position

This is a fully remote, project-based contract role focused on creating challenging coding tasks from visual materials such as screenshots, UI mockups, diagrams, and screen recordings of real workflows. The work involves specifying the code and artifacts involved, expected behavior, and objective success criteria that make it possible to verify whether a task was completed correctly. You will also provide working reference implementations, review tasks created by other contributors for technical accuracy and verifiability, and flag tasks that are ambiguous or cannot be graded reliably. The engagement is paid per approved task. Each task takes approximately eight hours and pays approximately $640–$800, equivalent to $80–$100 per hour.

Requirements

• Have a public GitHub profile with substantial, verifiable contributions, such as commits, merged pull requests, or maintained repositories; this is essential.
• Have strong frontend engineering skills in React, TypeScript, or similar technologies, with experience shipping complex interfaces and interactions.
• Be able to read, modify, debug, and validate real application code.
• Have strong written English and the ability to explain expected behavior and reproducible verification steps.

Nice To Haves

• Experience with UI, graphics, SVG, or Canvas work.
• Product or UI designers with hands-on frontend implementation experience and public code contributions are also a fit.
• Prior data labeling, AI evaluation, or rubric-based review experience.

Responsibilities

• Design multi-step coding tasks grounded in screenshots, UI mockups, diagrams, or screen recordings of real workflows.
• Specify the code and artifacts involved in each task and define expected behavior.
• Define objective success criteria for verifying task completion.
• Provide a working reference implementation.
• Review tasks created by other contributors for technical accuracy and verifiability.
• Flag tasks that are ambiguous or ungradable rather than submitting them.
