About the role

Build rigorous, visually grounded coding tasks that test real frontend engineering ability. You will turn screenshots, UI mockups, diagrams, and recordings of real workflows into multi-step implementation challenges with clear, reproducible ways to verify success.
Key Responsibilities: Create coding tasks based on visual source material, defining the required code, artifacts, and expected behavior. Establish objective completion criteria so work can be verified for correctness, not merely plausibility. Develop a working reference implementation for each task. Review tasks created by other contributors for technical accuracy and verifiability. Identify and flag tasks that are ambiguous or cannot be reliably graded.
Qualifications: Public GitHub profile with substantial, verifiable contributions, such as commits, merged pull requests, or maintained repositories. Strong frontend engineering experience with React, TypeScript, or comparable technologies, including shipping complex interfaces and interactions. Ability to read, modify, debug, and validate real application code. UI, graphics, SVG, or Canvas experience is especially valuable. Product or UI designers with hands-on frontend implementation experience and public code contributions are encouraged to apply. Strong written English and the ability to document expected behavior and reproducible verification steps. Experience in data labeling, AI evaluation, or rubric-based review is helpful but not required. Work Terms Remote independent contractor engagement. Project-based work, paid per approved task. Each task typically requires about 8 hours. Compensation Hourly compensation is listed at $70 to $100 per hour. Task compensation is approximately $640 to $800 per approved task, equivalent to roughly $80 to $100 per hour.
Application Process: Submit an application and complete the screening questions. Complete an AI interview so your relevant expertise can be evaluated for the role. Your profile will be reviewed, followed by setup for accepted candidates.

Before you apply

Applying takes about a minute. These four things decide how fast it moves after that.

Your profile is current

It's what we read first. Occupations, seniority and locations matter more than a long history.

Two examples you can talk through

Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.

A number in mind

What you're on now and what would make you move. We negotiate better when we know both.

Your notice period

Employers plan around it, and it's the question that stalls offers most often.

Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
