Note: The job is a remote job and is open to candidates in USA. JobHub by NeonLabs, in partnership with Mercor, is seeking experienced frontend and full-stack software developers to support leading AI labs in training frontier models on frontend code evaluation. The role involves evaluating AI-generated frontend code against reference web pages, assessing visual fidelity and code quality, testing responsiveness, and providing evidence-based justifications while collaborating remotely with AI researchers.
Responsibilities
- Render reference web pages and candidate replications at a 1920×1080 viewport to judge closer reproductions state-by-state
- Diff visual fidelity in detail: box model and spacing, typography, color and borders, asset handling, z-order, and overflow
- Read source code of model attempts to grade construction quality—distinguishing genuine correctness from superficial rendering (spotting hardcoded offsets, absolute positioning standing in for layout, inline style soup, etc.)
- Test responsiveness and write specific, evidence-cited justifications for every preference
- Collaborate remotely with leading AI researchers to shape code-generation AI systems without utilizing confidential or proprietary employer information
- Submit your application via the link above
- Qualified candidates with prior completed Mercor engagements may move through the selection process
- Conduct quick AI interview
- Projects can be extended, shortened, or concluded early depending on needs and performance
Skills
- 3–8 years of professional web development experience, shipping web interfaces for a living (frontend or full-stack)
- Fluency across web eras: command of hand-written HTML/CSS, semantic markup, modern layout (flexbox, grid), and legacy float- and table-based layouts
- Browser DevTools as muscle memory and command-line comfort for standing up local static servers and unzipping site trees
- At least one completed Mercor engagement, delivered in full (net-new experts are not onboarded to this project)
- Access to a desktop or laptop with a 1920×1080 viewport and administrator rights to run a local server
- Professional written English for drafting clear, evidence-based task justifications
- Location Requirement: Open across eligible regions (including United States, Canada, United Kingdom, EU member states, and Latin America)
- Schedule: Flexible schedule requiring contiguous multi-hour blocks (~2–3 hours per unit)
Benefits
- Fully remote role
- Can be completed on your own schedule
- Weekly payouts via Stripe or Wise
- Work directly alongside leading AI labs on frontier code-evaluation and model training
- Opportunity to shape the next generation of AI coding assistants and code evaluation benchmarks
- Flexible schedule
