We are looking for Frontend / UI Engineer candidates for a project delivered through the hiring partner.
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 you need
- A public GitHub profile with substantial, verifiable contributions — commits, merged PRs, or repositories you maintain.
- Strong frontend engineering: React, TypeScript, or similar, with experience shipping complex interfaces and interactions.
- Able to read, modify, debug and validate real application code.
- Strong written English, and the ability to explain expected behavior and reproducible verification steps.
Nice to have
- Experience with UI, graphics, SVG, or Canvas work.
- Product or UI designers with hands-on frontend implementation and public code contributions.
- Prior data labeling, AI evaluation, or rubric-based review experience.
