Frontend / UI Engineer

Job Description

Role Title: Frontend / UI Engineer

Role Type: Contractor

Location: Remote

Opportunity Snapshot

Pay: $80–100/hour equivalent (approximately $640–800 per task)

Time per task: ~8 hours

Engagement: Project-based — paid per approved task

Location: Fully remote

You’ll need: A public GitHub profile with substantial, verifiable contributions

Your tasks: Turn screenshots, diagrams and videos into challenging coding tasks with objective success criteria

What you’ll do

Design multi-step coding tasks grounded in visual material: screenshots, UI mockups, diagrams, or screen recordings of real workflows.

Specify which code and artifacts the task involves, and what the expected behavior is.

Define objective success criteria — how someone would verify the task was completed correctly, not just plausibly.

Provide a working reference implementation.

Review tasks built by other contributors for technical accuracy and verifiability.

Flag tasks that turn out to be ambiguous or ungradable rather than submitting them.

What we’re looking for

A public GitHub profile with substantial, verifiable contributions — commits, merged PRs, or repositories you maintain. This is essential.

Strong frontend engineering: React, TypeScript, or similar, with experience shipping complex interfaces and interactions.

Able to read, modify, debug and validate real application code.

Experience with UI, graphics, SVG, or Canvas work is especially valuable.

Product or UI designers with hands-on frontend implementation and public code contributions are also a fit.

Strong written English, and the ability to explain expected behavior and reproducible verification steps.

Prior data labeling, AI evaluation, or rubric-based review experience is a plus, not a requirement.
