Location: Remote
Commitment: 10–40 hours/week
What You'll Do
- Review and evaluate AI-generated JavaScript code for correctness, efficiency, and adherence to modern ES6+ standards.

- Identify bugs, edge cases, and failure modes in AI-generated web and backend code.
- Craft clear, human-readable explanations of code logic and problem-solving approaches.
- Provide structured, detailed feedback that helps AI models produce better, more reliable code.
- Work independently and asynchronously — fully on your own schedule.
Who You Are

- 3+ years of hands-on experience with modern JavaScript frameworks such as React, Node.js, or Vue.
- Strong instincts for clean, readable, maintainable code — you know the difference between code that works and code that's well written.
- Naturally detail-oriented with a methodical approach to evaluating quality.
- Able to articulate technical reasoning clearly in writing.
- A degree in Computer Science or a related field is preferred, but demonstrated experience matters most.
Nice to Have
- Experience with data labeling, RLHF, or other AI training workflows.
- Familiarity with TypeScript or modern JavaScript toolchains (Webpack, Vite, ESLint, etc.).
- Background in code review, technical writing, or software quality assurance.
- Experience working across both frontend and backend JavaScript environments.
